The Effects of Priority Forestry Programs on China’s Rural 25
Household Income 26
27
Abstract: the paper use 2070 balanced panel dataset, and cluster-specific fixed effect model is 28
used. We find the PFPs have mixed effects on China’s rural household income, and also these 29
impacts of the PFPs on rural household total income, land-based income and off-farm income 30
have been changing with the year. 31
Key words: Priority Forestry Programs, rural household, income, impact, China 32

1. Introduction 34
With an eightfold increase of per capita gross domestic product (GDP) since 1978, China has 35
witnessed tremendous economic growth over the past three decades (Zheng et al. 20081). 36
Accordingly, Chinese population living in absolute poverty (below a per capita annual income of 37
637 Yuan in 1995 real price) was over 250 million in 1978, but it reduced to 21.5 million by the 38

end of 2006 (China National Statistics Bureau 2 , or CNSB, 2007). Despite these great 39
achievements, poverty, especially in the rural areas of western China, remains a troublesome 40
phenomenon. Residents living below the World Bank poverty line of $1 per capita per day 41
amounted to 135 million in 2004 (Chen and Ravillion 20043). In its “Human Development Report 42
2005,” the United Nations Development Program (UNDP4) noted that the pace of poverty 43
alleviation in China has slowed down markedly over the past decade (UNDP 2005). Obviously, 44
how to further reduce rural poverty and increase farmer’s income still is a top policy priority to the 45
Government of China. 46
Forests often play a crucial role in the lives of many poor people. Worldwide, almost 70 million 47
people – many indigenous – live in remote areas of closed tropical forests and another 735 million 48
rural people live in or near tropical forests and savannas (FAO 20065, World Bank 20006). In 49
China, most of its 592 poverty counties are found in areas that are far away from urban centers 50
and have poor traffic access; meanwhile, they tend to possess relatively plentiful forests (State 51
Forestry Administration, 20037). In numerous impoverished places, forestry has indeed been a 52
main source of income for farmers (Liu and Lv 20088). 53

A crisis-response model offers a more credible explanation, the perception of crises, for example, 54
wood scarcity in the early 19th and Alpine floods in mid-century in France, the occurrence of 55
floods and avalanches in mid-19th century in Switzerland, floods and mudslides in Thailand in 56
1988, and the devastating floods in 1991 in Philippines (Mather et al. 19999; Hirsch and Lohmann 57
198910) was significant active factors with favorable circumstances, policies of these countries 58
have changed, some of them have increased forest resources and some of them are still in the stage 59
of deforestation. Cultural and political climates were highly significant in facilitating effective 60
intervention. The crisis resulting from destructive exploitation was the stimulus for the 61
introduction of new regimes of resource management (Friedrich 1904)11. The serious natural 62
disasters that China suffered in 1997 and 1998 spurred new efforts to protect the country‘s fragile 63
and fragmented environment. Due to severe droughts in 1997, the lower reaches of the Yellow 64
River dried up for 267 days, putting industrial, agricultural and residential water uses in the north 65
plains in great jeopardy (Xu and Cao 2001)12. In 1998, massive floods along the Yangtze River, 66
Songhua River and Nei River claimed that the lives of over 3000 people and led to more than 67
US$ 12 billion in property damages and production loss (State Forestry Administration 2001)13. 68
Serious soil erosion and sandstorm occurred in the later 1990s in the northern China (Liu and 69
Zhang 200614). In the meantime, Chinese grain production reached to historical high, grain price 70

has reached a low level (Liu and Wu 201015). The Southeast Asian crisis affected Chinese 71
economic development; the Government of China took measures to stimulus economic recovery 72
with its abundant financial revenue. Under these circumstances, the Government of China 73
launched six Forestry Priority programs (PFPs) for environmental restoration and pushing 74
economic growth and adjustment of rural economic structures and poverty reduction since 1998. 75
These contexts triggered the government to initiate the Natural Forest Protection Program (NFPP) 76
in 1998 and the Sloping Land Conversion Program (SLCP) in 1999. The U.S Department of 77
Agriculture’s Conservation Reserve Program has many features in common with the SLCP 78
(Uchida et al. 200516; Johnson and Maxwell 200117; Wang and Maclaren 201118). And some forest 79
transition countries have abandon their least productive lands which then revert to forest 80
(Meyfrodt Rudel and Lambin 2010)19 Following successful experimenting during 1998-1999, the 81
NFPP was formally launched in 2000 with an initial investment of 96.4 billion Yuan for the 82
decade (This is equivalent to roughly US$14.1 billion given the current exchange of $1 = 6.85 83
yuan in 2000). A key component of the NFPP was commercially logging bans over 30 million 84
hectares of natural forests in the upper reaches of the Yangtze River and the upper/middle 85
reaches of the Yellow River. In other areas (such as the Northeast, northwest of China and Hainan 86
Province), harvest restrictions were tightly imposed. The SLCP was piloted in Sichuan, Shaanxi, 87
and Gansu provinces in 1999 and 2000 (also known as the ‘Grain for Green’ program in the 88

international literature). The SLCP was formally implemented in 2001. Its primary goal was to 89
convert 14.6 million hetares of sloping and desertified farmland into forest and grass coverage 90
from 2001 to 2010. When it was formally launched, the SLCP extended to and covered 25 91
provinces, with a budget of 225 billion Yuan. In addition to the above two mega programs, a 92
number of other efforts of ecological restoration and forest expansion have been consolidated into 93
the following four programs: the Desertification Combating Program around Beijing and Tianjin 94
(DCBT), the Shelterbelt Development Program in the Three-Norths (the northwestern, 95
north-central, and northeastern regions of China) and the Yangtze River Basin (SBDP), the 96
Wildlife Conservation and Nature Reserve Program (WCNR), and the Industrial Timber 97
Plantation Program (ITPP) (See table 1). Together with the NFPP and the SLCP, these programs 98
comprise the six PFPs (SFA, 2005). From 1998 to 2009, the afforestation area of NFPP, SLCP, 99
DCBP, SBFP and ITDP is 7957.3 thousand hectares, 21633.4 thousand hectares, 4160.3 thousand 100
hectares thousand hectares, 13872.6 thousand hectares and 846.3 thousand hectares (State Forestry 101
Administration 201020). Rural households have been involved in the implementation of these PFPs, 102
for instance, by the end of 2008, 26.84 million rural households have been involved in SLCP in 25 103
provinces, and 2.52 million rural households have been involved in DCBT in 75 program counties 104
of 5 provinces (Beijing, Tianjin, Hebei, Shanxi and Inner Mongolia). Household forestlands in 105
NFPP area have been coved for NFPP, SBDP, ITPP and WCNR; in the meantime, some of rural 106
households have inputted their labors and capitals in SBDP, ITPP and WCNR. 107

Ecosystem services are increasingly recognized by governments as natural capital assets that 109
provide benefits to society (Millennium Ecosystem Assessment 2005). The U.S Department of 110
Agriculture’s Conservation Reserve Program has many features in common with the SLCP 111
(Uchida et al. 200521; Johnson and Maxwell 200122). And some forest transition countries have 112
abandoned their least productive lands which then revert to forest (Rudel and Lambin 2010)23. At 113
a time when ecological restoration has become a common cause and payment for ecosystem 114
services has been widely promoted in pursuant of sustainable development (FAO 200924, 115
Millennium Ecosystem Assessment 2005, Li, Feldman, Li and Daily 201125), Thailand, Indonesia 116
and other countries have launched Logging Ban programs similar to NFPP (FAO 2009), and Wild 117
life and natural reserve programs, timber plantation programs have been widely adopted 118
worldwide, scrutinizing China’s recent experience in general and its implementation of the PFPs 119
in particular is interesting. This is because evaluating the program impacts on participating 120
households’ welfare is essential to determine the directions toward which public funding and 121
policy should be mobilized. Lessons learned from China can thus benefit many other countries, 122
especially developing counties that face challenges of both environmental protection and poverty 123
reduction. 124
From the perspective of rural households, the direct effects of these PFPs are reflected mainly in: 125
(1) the government subsidies they receive for retiring and converting the sloping and desertified 126

cropland or rehabilitating grassland (under the SLCP or the DPBT); (2) the government 127
restrictions imposed on their logging, collecting, and even managing practices in case their forests 128
are put under protection for providing more important ecosystems services (under the NFPP or the 129
WCNR); and (3) the government incentives offered for them to engage in plantation and 130
shelterbelt establishment and other related activities (under the ITPP or the SBDP) (see table 1). 131
There exist numerous tradeoffs, most of which can result in changed patterns of land use and 132
production. Induced by the land reallocation and production shift, farmers have to intensify 133
farming and commercial forestry activities on their remaining lands, switch animal husbandry 134
from open gazing to pen raising, or search for off-farm jobs and others in order to sustain their 135
income growth. Therefore, it is expected that following their participation in the PFPs, farmers’ 136
income sources and employment structure, production technology will undergo major 137
transformation. To be sure, in addition to farmers’ own initiatives, efforts, and inputs, the extent 138
and trend of their income and employment changes depend critically on the availability and 139
effectiveness of technical, financial, and personnel assistances provided by the local public 140
agencies. Finally, after the implementation of PFPs, the local ecological conditions have changed 141
which would or might benefit for local production, and further affect rural households’ income and 142
poverty reduction. 143
So far, implementing these PFPs has substantially altered the land use patterns in many upland 144
regions, where both a significant portion of the country’s primary forest ecosystems and a high 145
rate of poverty incidence are found. As a result, a large amount of sloping cropland has been 146
converted to forest and grass coverage and many existing forests, including quite some managed 147
ones, have been subject to strict regulation for commercial use. Thus, a question of broad interest 148
9 / 48
and major relevance is: How has implementing the PFPs affected the farmers’ income? And 149
what and how has affected on rural poverty reduction by these PFPs? And what and how has the 150
rural poor been affected by these PFPs? The key objective of the paper is to address this question 151
empirically. In the meantime, these PFPs will continue to implement in the 12th-Five-Year 152
National Plan (2011-2015) and the 13th-Five Year National Plan (2016-2020), based on our 153
empirical results, shall we find the alternatives for balancing rural household livelihood and 154
ecosystem restoration or not? 155
The impacts of the SLCP on farmers’ income and livelihood have received a great deal of attention 156
in the literature. Yao, Guo and Huo(2010) use panel dataset of 600 household in three counties in 157
the Loess Plateau region and find that the effect of SLCP on rural households’ crop production 158
income, animal husbandry income and off-farm income varied substantially26. With sample data 159
collected from four counties in Shaanxi Province and Qinghai Province, Xie and et al (2006) 160
demonstrate that SLCP could provide increased household net profits and claim that their result is 161
robust under a range of discount rate and output prices27. Liu and et al (2010) use the dataset of 162
10-year and 15 county-household in 6 province and their results show that the SLCP has 163
significant contribution to rural household income 28 . In addition to examining its cost 164
effectiveness and sustainability, Uchida et al. (2005) 29and Uchida et al. (2007) 30analyze its 165

influence on eradicating poverty in the countryside. They find that the program has been 166
successful in poverty alleviation, even though poor households may not have benefited the most. 167
Further, their evidence suggests that households participating in the program have already begun 168
transferring their labor to non-farming sectors more rapidly than those not participating in the 169
program. In contrast, using data collected from Sichuan, Shaanxi, and Gansu for the first few 170
years of the program, Xu and Qin (2004)31 show that it made little difference in affecting farmers’ 171
income between. Their conclusion thus implies that the SLCP’s role in relieving poverty is limited; 172
the reduction of poverty is more likely driven by the overall economic development, which 173
provides greater opportunities to farmers, rather than the direct subsidies of the land conversion. 174
Wang and Maclaren (2011) uses a dichotomous logistic regression analysis and find that “the 175
farmers may be forced, by economic necessity, to return to their former practices when a project 176
such as SLCP does not provides them with ability to find a new way of life after the compensation 177
ends” in Dunhua County, China. 178
Observers also point out that in some cases, the goal of the program is not well understood by 179
farmers; and it may even be inconsistent with their aspirations, which have affected their 180
enthusiasm for participation (Du 200432). According to Xu (200333), the main reasons that some 181
farmers lack interest in the program are partly because the subsidies are not delivered on time and 182
in full, and partly because no appropriate remedies were put in place to address the restrictions on 183

intercropping in the forested fields and gathering fuelwood. These factors have led to an adverse 184
effect on the livelihoods of the farmers, who not only rely heavily on forest resources but also tend 185
to be among the poorest rural population. Based on case studies in the upper watersheds of the 186
Mekong and Salween Rivers in north-western Yunnan, Weyerhaeuser et al. (2005)34 also reveal 187
certain negative impacts of the SLCP and the NFPP on the livelihoods of highland communities. 188
The study by Zhi and Shao (2001) 35claims that the income of farm households would be 189
significantly improved during the time period of government subsidies. If the subsidies are 190
terminated after the program expires in 5-8 years and farmers are not allowed to utilize their 191
retired lands for economic purposes, they could suffer a loss. In their opinion, the policy that 192
mandates that the proportion of economic forest be no more than 20% has failed to consider the 193
regional disparity and the basic fact that the country has a large rural population but a relatively 194
small amount of cropland. Thus, the government must take steps to improve farmland quality and 195
increase farming productivity in order to address the issue of food supply following the land 196
conversion. In addition, Xu et al (2010) find that “SLCP has indeed induced a restructuring of 197
agricultural production, whereby participants have shifted relatively more of their inputs out of 198
cropping and into animal husbandry”.36 199
Compared to the SLCP, there have been fewer studies of the socioeconomic impacts of the NFPP 200
and other programs. Xu and et al (2002) found that NFPP caused income losses for households 201
dependent on the state and collective forest sectors37 . Shen and et al (2006) carried out 202

input-output analysis model and found that that combined impacts of logging ban and the 203
afforestation activities would likely increase output and employment in the economy as a whole38. 204
Using household data, Ni et al. (2002)39, Liu et al. (2005)40, Xu and et al (2006)41 demonstrate 205
that the NFPP had a negative effect on the income of farmers living close to the protected natural 206
forests. But some researchers have found the different impacts of NFPP on rural household. 207
Mullan and et al (2010) find that the NFPP has had a negative impact on income from timber 208
harvesting but has actually dad a positive impact on total household incomes from all sources42. 209
Liu and et al (2010) find the impact of NFPP on rural household income have experienced from 210
the negative to the positive. With data from 18 counties in Shanxi, Inner Mongolia, and Hebei, Liu 211
and Zhang (2006) show that the DCBT had a positive effect on farmers’ income, but the effect 212
varied from county to county, due in part to uneven program investments. However, they did not 213
consider all of the relevant factors affecting farmers’ income, including production inputs and 214
household characteristics. 215
To our knowledge, 1) little work has been conducted so far to make an integrated assessment of 216
the impacts of the PFPs except Liu and et al (2010) and Weyerhaeuser et al. (2005). In fact, most 217
of the existing studies have focused on a single PFP, with few studies dealing with two or more. 218
This is unfortunate given the fact that these overlapping PFPs have all somehow affected farmers’ 219

income and their impacts may interact (Yin and Yin 200943). 2) Most of these researchers used the 220
data of the early implementation period of these PFPs, and they did not update their data. 3) 221
Policies and institutional arrangements have been changed since the early period of these PFPs, 222
for example, the key and most important policies were issued by the central governmental 223
agencies for SLCP in 2005, 2007. Therefore, the impacts of these new policies and institutional 224
changes should be considered. 4) Rural policies have been changing since the implementation of 225
these PFPs, which have affected rural households’ income and production choices. 5) The reform 226
of the collective forestland tenure has been implemented since 2003, which has impacted farmers’ 227
forestland and forest resource management, and their production choices. And finally, 6) financial 228
crisis has been also affecting the implementation of PFPs and rural households’ production choices 229
and income and income sources generated. In conclusions, there is a great gap in this aspect. We 230
will use our data to analyze the impact of rural households’ income and poverty reduction and 231
narrow the gap. 232
We use the unique balanced panel dataset of 2070 household of 14years in 15 counties of six 233
provinces (Shandong, Jiangxi, Sichuan, Guangxi, Hebei and Shaanxi), with cluster-specific fixed 234
effect model, we estimate the effects of these five PFPs (due to limited samples of WCNR, we do 235
not estimate the effects) on rural household crop production income, forest income, animal 236
husbandry income, land-based income, off-farm income and total income in general, we also 237
estimate these effects of five PFPs on above income sources by year. We find that the effects on 238
these income sources are mixed, and change by year. 239

update these samples with the proposed financial aid (partial aid, we will use other research funds). 244
Broader cross sections and longer time series are two unique features of this dataset. That is, every 245
sample county has at least two PFPs and covers a period of 15 years from 1995, before they were 246
initiated or consolidated, to 2009, when their implementation was well underway. This large and 247
comprehensive dataset, allows us to control for many relevant covariates, including production 248
inputs and household and village characteristics.. 249
The objective of this paper is to quantify the impact of the PFPs on household incomes in affected 250
areas. In order to this, we need to deal with an identification problem: if there are two potential 251
outcomes, Y1, the outcome when the individual participates in a programme; and Y0, the outcome 252
when the individual does not participate, then the impact of participating in the programme is 253
given by: 254
01 YY −=Δ (1) 255
However, estimating this requires information on both Y1 and Y0 for each individual, which is not 256
obtainable because we cannot observe the outcome of participation for non-participants or the 257
outcome of non-participation for participants. Therefore, estimation of the causal effect of the 258
15 / 48
programme is equivalent to solving a missing data problem (Heckman et al. 199744), and requires 259
the use of techniques that allow the identification of the relevant impacts in the absence of the data. 260
In the case of the PFPs, we want to know the difference between the level of household income 261
when a household is in the programme and when they are not, but we only have data on one 262
situation or the other. 263
For any individual, the observed outcome (Y), following Roy (1951)45, Quandt (1972)46 and 264
Rubin (1978)47, is defined as: 265
01 )1( ititititit YDYDY −+= (2) 266
where D denotes participation in the program, and takes the values 1 (if the individual 267
participates/is treated) or 0 (if the individual does not participate/ is not treated). This can be 268
written as a function of observable characteristics of the individual (xit), unobservable, 269
time-invariant individual-specific effects (αi), and individual-specific disturbance terms (uit1, uit0,). 270

The estimated treatment effects may be biased if the individual-specific effect or the disturbance 275
term are correlated with participation in the program. The former may occur if unobserved 276
characteristics of the individual affect the probability that they will participate in a PFP. This is 277
likely in the case of voluntary (or semi-voluntary) programs such as the SLCP. It is less likely for 278
programs such as the NFPP in which partipation is decided at the county-level rather than by 279
individual households. The latter would be an example of what is referred to as ‘Ashenfelter’s dip’ 280
– if individuals experience unusually low or high incomes immediately prior to entering a program, 281
the estimated returns to treatment will be biased in a context of mean reversion. 282
There are various methods to estimate a counterfactual outcome against which the outcome for 283
treated individuals can be compared (e.g. Heckman and Robb, 1984; Ashenfelter and Card, 198548; 284
Heckman et al., 1997). The available of panel data allows us to use a fixed-effect model to control 285
for individual-specific heterogeneity that could affect the outcomes of partipation as discussed 286
above. We can consistently estimate average treatment effects on the treated as long as the 287
treatment varies over time and is uncorrelated with time-varying unobservables that affect the 288
outcome of interest. It is also necessary to assume that time trends in the outcome variable among 289
program participants and non-participants are the same. We test these assumptions through 290
comparison of trends in income in the treatment and control groups prior to the introduction of the 291
PFPs. 292
We focus on the impacts of participation in a single PFP or more than one PFP on total income and 293 48 Ashenfelter O. & Card D. (1985) Using the Longitudinal Structure of Earnings to Estimate the Effect of Training Programs. The Review of Economics and Statistics. Vol. 67, No. 4 (Nov., 1985), pp. 648-660.

income from different sources. The impacts on total income are expected to differ because of 294
differences in the characteristics of the individual programs. Each of the programs involve 295
changes in the production activities or land uses of farm households. However, some, such as the 296
SLCP, provide compensation for those changes, while others, such as the NFPP, involve 297
restrictions on households’ resource use rights without compensation. As a result, there will be 298
direct and indirect impacts on household incomes, and these may be positive or negative. The 299
PFPs overlap, both spatially and temporally. We therefore include the interaction effects between 300
the most widespread policies in order to determine whether the combined impacts differ from the 301
individual impacts. Participation in a program is measured using a binary variable for program 302
participation, and using a continuous variable representing the area of land enrolled in each 303
program. 304
The extended production function and cluster fixed model is used. The definitions of these 305
variables are listed in table 2. 306
[Insert table 2 here] 307
3. Data 308
The strained random sample model was adopted in this study. In light of the distributions of the 309
rural households’ income and the PFPs as well as our discussions with officials of provincial 310
forestry and other departments and local experts, we first selected 15 counties for our surveys. 311
They are Zhangbei, Pingquan and Yixian in Hebei Province; Xiushui, Xingguo and Suichuan in 312
Jiangxi Province; Zhen’an and Yanchang in Shaanxi Province; and Nanbu, Nanjiang, Muchuan 313
18 / 48
and Mabian in Sichuan Province; Pingguo and Huanjiang in Guangxi Zhuang Nationality 314
Autonomous Region, and Pingyi in Shandong (see Fig. 1). Each of these counties has participated 315
in at least two of the PFPs with the exception of Pingyi County in Shandong Province being used 316
as the baseline county for comparison purpose. For instance, Zhangbei County has participated in 317
the DCBT and the SBDP, and Nanbu County has participated in the NFPP, the SLCP and the 318
SBDP (see Table 3 and Fig.1 ). 319
[Insert Fig. 1 and Table 3 here] 320
Sample villages and households were chosen randomly. Specifically, we chose the villages from 321
the village list of a county and households from the household list of a village. Except for 322
Zhangbei (of 270 sample households, we selected 90 households in each township) and Huanjiang, 323
Pingguo, Yixian, Muchuan and Pingyi (of 135 sample households, we selected 45 households in 324
each township) where three townships were selected, six townships were chosen in all other 325
counties. Overall, 15 households were chosen in each sample village except for Zhangbei County 326
(30 households were chosen). Altogether, we interviewed 3,375 households in 216 villages of 72 327
townships. Our initial survey was conducted in 2004 as part of our program monitoring and 328
assessment efforts supported by the Asian Development Bank and the Chinese Ministry of 329
Finance. To understand the microeconomic shifts over time, we asked interviewees to recall their 330
production activities and other relevant information back to 1995. Then, in 2005, 2006, 2007, 331
2008 and 2009, we repeated our surveys. As such, we were able to assemble a panel dataset 332
covering fourteen years (1995-2008), which has a longer and more continuous coverage than 333
almost any other datasets used by others to assess the impacts of the six PFPs. In order to help 334
19 / 48
interviewees to describe their production and consumption behaviors, we designed the 335
questionnaires in terms of specific production and consumption activities, and asked multiple 336
family members to recall their household activities in each year, and cross-checked the responses 337
by consulting with village resource persons and statistical data and information of case study 338
counties, townships and villages. All these steps served to ensure high quality of the data 339
collected. 340
However, our surveys did not contain complete information from some households. This is 341
because a few of them moved away from the sample villages, errors occurred to some interviews, 342
or certain families failed to clearly and exactly recall what had happened to them in the previous 343
year(s). These factors led to the outcome of a slightly unbalanced panel over time. To measure 344
rural households’ income mobility, we need a balanced panel dataset. We decided to remove those 345
observations with incomplete information and/or incomplete interviews, resulting in a balanced 346
panel of 2070 households for the study. 347
It is evident from Table 3 that, over the study period, more and more households were involved in 348
the PFPs. Since the launching of these PFPs in 1998, the number of households that were not 349
involved with the PFPs declined from 1507 in 1998 to 508 in 2008. While some participated in 350
multiple PFPs, others did not participate in any of them. While 33 households participated in both 351
the NFPP and the SLCP in 1999, the figure increased to 656 households by 2008. Meanwhile, 9 352
households were involved in the SLCP, NFPP and SBDP in 2008 (see Table 3). More specifically, 353
a large number of households took part in the NFPP and the SLCP, but only a few were involved 354
in the SBDP and even fewer in the ITPP. By the end of 2008, the sample households that 355
20 / 48
participated in the NFPP, SLCP, DCBT, ITPP, SBDP, SLCP&NFPP, SLCP&ITPP, DCBT&SBDP, 356
NFPP&SBDP, ITPP&SBDP and SLCP&NFPP&SBDP were 291, 236, 277, 12, 51, 656, 2, 19, 1, 6, 357
0, 2 and 9 household (s) respectively (see table 4). Table 3 also indicates that most of these 358
sampling households participated in the NFPP and the SLCP. Only few households participated in 359
ITPP. There are 508 households that did not participate in any PFPs until 2008; these households 360
are allocated both PFP areas and non-PFP area. 361
[Insert Table 4 here] 362
The NFPP and the SLCP were initiated in Sichuan and Shaanxi provinces in 1998 and 1999, 363
respectively; and Jiangxi Province and the Guangxi Zhuang Autonomous Region were included in 364
the SLCP in 2001 and 2002, respectively. Both the SLCP and the DCBT were launched in Hebei 365
Province in 2000. 366
We could find that these counties are located in the east, west, north and south of China, although 367
rural households’ Total income in some counties is lower that of the national average (such as 368
Zhangbei County and Mabian County, some counties’ rural households’ income is the same as the 369
national average (such as Yi County) or higher than that of the national average (Pingyi County 370
and Muchuan County). It is to say, these samples of rural households are in fact representative of 371
the rural China and these PFP areas (see Fig. 1). 372
Included in the dataset are the following variables: (1) household demographics (household size, 373
educational achievement of the household head, and the like); (2) monetary outputs (total income, 374
off-farm income, and income from land-based enterprises) and inputs (labor, farmland, cash 375
21 / 48
expenditure, etc.) for land-based and off-farm activities; (3) the statuses of the PFP participation; 376
and (4) natural and socioeconomic conditions (annual precipitation and average plot sizes of 377
forestland and farmland). We collected case study provincial and county statistics data for the 378
research. 379
Total income and cash outlay of sample households were deflated and converted to the 1994 380
constant yuan, using the rural consumer price index and rural industrial product price index from 381
the Chinese Statistical Yearbooks, published by the China National Statistical Bureau (2009). 382
Average annual household total income has been increasing since 1995, with the amount being 383
4282.06 yuan, 5045.84 yuan, 7229.39 yuan and 12505.30 yuanin 1995, 1999, 2004 and 2008 384
respectively (see Table 4). The weight of off-farm income was 69.09%, 58.90% and 62.96% in 385
1995, 1999, 2004 and 2008, respectively. The level of production expenditure for land-based 386
activities has been increasing, being 524.37 yuan, 613.85 yuan, 714.33yuan and 1526.62 yuan in 387
1995, 1999, 2004 and 2008, respectively. Among the land-based income included crop production 388
income, forest income and animal husbandry income and other land-based income, crop 389
production income does not change too much, while forest income and animal husbandry income 390
increase rapidly, i.e. from 1995 to 2008, rural household forest income increases from 355.08 yuan 391
to 1098.26 yuan; their animal husbandry income also be up from 947.77yuan to 2196.15 yuan. All 392
these data indicate that rural household income sources have greatly changed since 1995. Rural 393
housed average off-farm labor input has increased from 88.75 person-days in 1995 to 269.35 394
person-days in 2008, while land-based labor input has decreed 245.95 person-days in 1995 to 395
186.77 person-days in 2008. Road condition has somewhat improved especially in 2008 due to the 396
new rural construction in China. 397
22 / 48
With the implementation of the PFPs, rural household land structure has been changing. Farmland 398
area per household decreased from 8.27 mu49 in 1995 down to 7.97 mu in 1999, 5.77 mu in 2004 399
and to 5.66 mu in 2008; meanwhile forestland area per household rose from 9.90 mu in 1995, to 400
10.61 mu in 1999, 14.40 mu in 2004 and 18.64 mu in 2008 respectively. Area of other land and 401
grassland types per household fluctuated during the study period. The household forestland area 402
expand is the PFPs and the reform of the collective forest tenure in China, especially after 2003 403
when the reform was launched, the Government of China decided to allocate collective forestland 404
to individual management. 405
Acreage enrolled in the SLCP and the NFPP is largest among these PFPs; the percentage of 406
household enrolled in the SLCP increased from 15% in 1999, 44% in 2004, and 47% in 2008; 407
during the same period, the area enrolled in the NFPP increased from 27%in 1999 to 44% in 2008; 408
and the weight that enrolled in the DCBT also increased from 0.00% to14% in 2008; the 409
percentage that households have enrolled in the SBDP has been up from 0.00% in 1999 to 4% in 410
2008; and the percentage that enrolled in the ITPP did not show significant change, from 0.00% in 411
1999 to 1% in 2008 (see Table 4). 412
The income of the sample rural households grew gradually and the average income per household 413
was 4,442.23 yuan (in 1994 constant price) in 1995 and then increased to 12,109.45 yuan (in 1994 414
constant price). The structure of income has experienced significant changes. The income from 415
cropland was the main source of income before 2005, in that the ratio of the income from cropland 416
declined from 68.56% in 1995 to 40.79% by 2004; the off-farm income became the main source 417
49 15 mu=1 hectare
23 / 48
of income in 2005 and 2006, with the ratio being 50.3% and 50.01%, respectively. Furthermore, 418
the ratio of subsidy from the PFPs in total income increased, as the ratios rose from 0.3% to 2.9%, 419
8.9% and 8.34% in 1995, 2000, 2005 and 2006, respectively (see Table 5). 420
[Insert Table 5 here] 421
4. Empirical results 422
A couple of technical issues – choice of random-effects vs. fixed-effects estimation technique and 423
potential endogeneity bias – must be resolved before any formal empirical attempt. First, note that 424
equation (2) can be estimated as a fixed-effect or random-effect model. Whether we adopt the 425
random-effects or fixed-effects estimation technique hinges on the outcome of a Hausman test 426
(Woodridge, 1999). To that end, we ran the corresponding regressions of the total income of 427
sample households against the PFP dummies. It is found that in both cases the χ values are 428
greater than the critical values at the 1% confidence level. These results indicate that we should 429
estimate a fixed-effects model, rather than a random-effects one. One advantage of the 430
fixed-effects estimation is its control over unobserved fixed factors that could confound the 431
estimation (Pender 2005). 432
Another key issue is the potential endogeneity bias – whether or not households’ participation in 433
any of the PFPs is endogenously decided. If households have the freedom to select for 434
participation, then their participation becomes endogenous and an assessment of the program 435
impact must be made accordingly. Otherwise, ignoring the endogenous choice by households will 436
lead to biased estimates (Woodridge 199950, Uchida et al. 200751). In the current context, 437
50 Wooldridge, J. M. (1999) Introductory Econometrics: A Modern Approach, South-Western College Publishing
24 / 48
endogeneity is most pertinent to the SLCP, Liu and et al (2010) used the same sample household 438
dataset (1995-2004) and their result has rejected the endogeneity test. The dataset given that the 439
other programs were largely imposed on the rural households, who had little power to determine 440
whether and how they should participate. In the meantime, the SLCP subsidy is much higher than 441
that the net return generated from the converted cropland. Fig 2 and 3 show that net returns 442
generated from unconverted cropland in Yellow River Catchment and the Yangtze River 443
Catchment, which is two or three times higher than that of the converted cropland (State Forestry 444
Administration 199852, Liu and Wu 2010), higher economic returns encourage rural households to 445
participate in the SLCP and also help us to reject the endogeneity test. 446
[Insert Fig. 2 and Fig. 3 here] 447
By use of cluster-specific fixed effect model, we estimate the effects of these five PFPs (due to 448
limited samples of WCNR, we do not estimate the effects) on rural household crop production 449
income, forest income, animal husbandry income, land-based income, off-farm income and total 450
income in general, we also estimate these effects of five PFPs on above income sources by year. 451
We find that the effects on these income sources are mixed, and change by year. The empirical 452
results are presented in table 5 ~8. 453
The paper focuses on the effects of PFPs on rural household income, although other variables are 454
important to explain for rural household income change, we will mainly discuss about these effect 455

of PFPs. With regard to rural household total income, from 1995-2008, the effects of the NFPP, 456
the SLCP, the SBDP and the DCBT on household total income are insignificant. The coefficient of 457
ITDP is -0.25 and significant at 0.10 level, the coefficients of interaction of NFPP and SLCP are 458
significant at 0.10 level and the coefficient is 0.08(see table 6). 459
The NFPP and the DCBT are insignificant to impact rural household total income, non-farm 460
income, land-based income, crop production income, forest income and animal husbandry income 461
(see table 6). The coefficient of the SLCP to land-based income, forest income is 0.23 and -1.93, 462
and significant at 0.05 level. The impact of the SLCP on off-farm income, crop production income, 463
animal husbandry and total income is insignificant. The impact of the interaction between the 464
NFPP and the SLCP is significant to total income (0.08 and significant at 0.10 level), land-based 465
income (0.24 and significant at 0.05 level), crop production income (-0.40 and significant at 0.05 466
level) and forest income (2.90 and significant at 0.01 level). The coefficient of the impact of the 467
ITPP on total income is -0.25 and significant at 0.10 level; on other income sources is not 468
significant. The SBDP has contributed to crop production income (0.68 and significant at 0.05 469
level), and has the negative impacts on land-based income (-0.21 and significant at 0.01 level) and 470
animal husbandry income (-3.83 and significant at 0.01 level) (see table 6). 471
Table 6 tells us the effects of the PFPs on rural household income from 1995-2008, the dynamic 472
effects of the PFPs on rural household total income, off-farm income and land-based income are 473
presented in table 7~9. Total income is used as the independent variable, the impacts of both the 474
NFPP and the DCBT on total income are not significant since their implementations. Since the 475
launch of SLCP, it has positively and significantly impacted the total income until 2005, but its 476
26 / 48
significant level has reduced from 0.01 level to 0.05 level, and the parameter has become smaller, 477
i.e. from 0.15 to 0.06; after 2005, the impact of the SLCP on total income is insignificant. The 478
coefficient of the impact of the interaction of both the SLCP and the NFPP on total income is 0.12 479
(from 1995 to 1999), 0.08 (from 1995-2007) and 0.08 (from 1995 to 2008) and significant at 0.10 480
level. The ITPP has a negative effect on total income except from 1995—2003 and significant at 481
0.01 level, 0.05 level or 0.10 level. The impact of SBDP on total income has been negative before 482
2005 and significant at 0.01 level, and it has been insignificant after 2005 (see table 7). 483
[Insert table 7 here] 484
With regard off-farm income, the NFPP, the DCBT, SLCP, the interaction of the NFPP and the 485
SLCP, ITDP have not affected rural household off-farm income since their implementations. The 486
impact of the SBDP on off-farm income is mixed (the coefficient is -1.16, -1.60 and 2.94 487
respectively and significant at 0.01 level or insignificant) (see table 8). 488
[Insert table 8 here] 489
When we consider the contributions of the PFPs to rural household land-based income, we find 490
that: (1) the effects of both the NFPP and DCBT on rural household land-based income are 491
insignificant since these two programs were launched. (2) The contribution of the SLCP is 492
positive and significant at 0.05 level or 0.01 level; and the coefficient changes from 0.23 to 0.42, 493
the coefficient increases from 0.26 in 1999 to 0.42 in 2001, and then gradually decreases from 494
0.42 to 0.23 in 2008. (3) The impact of the interaction of the NFPP and the SLCP is insignificant 495
before 2004, and after then is significant at 0.10 level or 0.05 level and the coefficient increases 496
27 / 48
from 0.17 to 0.24. (4) The contribution of the ITDP is -0.67 and -0.68 in 2005 and 2006, and 497
significant at 0.01 level, it is insignificant in the rest of years. (5) The impact of the SBDP is 498
negative and significant at 0.01 level, and the coefficient changes from -0.51 to -0.10 (see table 499
9). 500

5. Conclusions and discussions 502
Measuring the impact of these PFPs on rural household total income and different source incomes 503
is not a straightforward matter, mainly because the Chinese economy has undergone huge changes 504
since the programs have been in place. With introduction of the PFPs, as we discussed above, rural 505
household production endowments have been changing by year. Rural households participated in 506
the SLCP, their cropland was converted to forest or grass coverage, their cropland has been 507
decreased, while their forestland has been increased. Under the new context, as the rational 508
economic stakeholder, rural households allocate their production endowment to maximum their 509
benefits. 510
We use the unique balanced 2070 household panel dataset, the time span is 14 years. 511
Cluster-specific fixed effect model is used, observations within a cluster are thought to be 512
correlated as a result of an unobserved cluster effect (Wooldridge 200253). Cluster-specific fixed 513
effect model allows us to exclude coloration within the cluster the effects of PFPs on rural 514
household total income and other income sources are mixed. During the period from 1995 to 2008, 515

With regard to rural household total income, from 1995-2008, the effects of the NFPP, the SLCP, 516
the SBDP and the DCBT on household total income are insignificant. The impacts of ITDP and 517
the coefficients of interaction of NFPP and SLCP on total income are positive. In the Natural 518
Forest Protection Program area, both the SLCP and the NFPP are positive to rural household total 519
income (the contribution of the SLCP or NFPP=the coefficient of the SLCP or the NFPP + 520
the coefficient of the interaction coefficient of the SLCP or the NFPP * 0 or 1). The impacts of 521
PFPs on other sub-income are also mixed. If we consider the contribution(s) of the SLCP and the 522
NFPP to the total income, land-based income and forest income are positive, to crop production 523
income is negative, and to non-farm income and animal husbandry income are insignificant (see 524
table 6). 525
Our empirical results indicate that the impacts of PFPs on total income and sub-income sources 526
have been changing by year. Since the implementation of the SLCP, the contribution of the SLCP 527
to land-based income is positive and changing by year (see table 7) and to total income is positive 528
until 2006. If we consider the impact of the interaction of both of the SLCP and the NFPP, we will 529
find that the impact of the SLCP is positive in NFPP area until 2008 except 1995-2006. 530
As we find that not many sample rural households participate in the ITDP, we observed that rural 531
households rented their forestland to state forest farms or domestic and foreign forest enterprises, 532
and the forestland rent is lower compared to their productivity or profit, therefore, the impact of 533
the ITDP on household income is negative. 534
SBDP areas are allocated national wide, the governmental forest agencies required that these 535
participated households input their labors for afforestation or reforestation, and forest resource 536
29 / 48
management such as forest fire and pesticide control, governmental agencies did not pay subsidy 537
except 100 yuan per mu for afforestation or reforestation, after 2003, governmental agencies 538
annually paid 5 yuan per mu for the state sheltbelt forests. Therefore, the impacts of SBDP on 539
rural household total income and land-based income have experienced from the significantly 540
negative to the insignificant or negative coefficients have become smaller (see table 7 and 9). 541
The DCBT is composed of the SLCP, watershed management, and resettlement from the fragile 542
ecological sites and switch animal husbandry from open gazing to pen raising. The DCBT area is 543
located in the desertified area that covers 75 counties or banners of 5 province and municipalities, 544
in accordance with the policies for the SLCP (see table 1), if rural household conversed one mu 545
sloping or desertified cropland to forest or grass coverage, he or she has to plant one or more mu(s) 546
trees on the barren land, most of these rural households in the DCBT did not have the barren land 547
for afforestation, he or she has to use their desertified cropland for afforestation as the barren land, 548
which would reduce his or her net return after deducting the additional costs. Therefore, the effects 549
of the DCBT on rural household total income and land-based income are insignificant. 550
Among these five PFPs, more sample rural households participated in the NFPP and the SLCP. 551
After their participation, their behaviors have changed. With implementation of the SLCP, 552
cropland has converted to forest or grass coverage, it is easy for us to understand that the effect of 553
the SLCP on crop production income is negative. With strict control and conservation of 554
forestland, the impact of the SLCP on forest income is negative and significant within the period 555
from 1995 to 2008. The SLCP subsidy is much higher than that of net return generated from the 556
converted cropland, which increases land-based income, the SLCP is positive to total income and 557
30 / 48
land-based income of these sample rural households. These households who participated in the 558
SLCP also reallocate their production factors. To find the land-based activity intensity variations, 559
we calculated the indexes of production expenditure intensity and labor input for land-based 560
production intensity (see Table 9), their labor intensity index and the production expenditure 561
intensity index who participated in the SLCP is much higher that of those who did not participate 562
in the SLCP, for example, the labor intensity index increases from 1.00 in 1999 to 1.72 in 2003 563
and reduces to 1.43 for the SLCP participants, while for non-SLCP participants, the index is much 564
lower than that of the SLCP participants; the production expenditure intensity who participated in 565
the SLCP increased from 1.00 in 1999 to 11.54 in 2008, while for those whose did not 566
participate the SLCP, the index increased from 1.00 in 1999 to 4.59 in 2008 (see table 10). With 567
intensive land-based activities, the outputs of land-based activities are higher than that period 568
before the implementation of the SLCP. In accordance with the policy documents, the 569
governmental agencies have strengthened the technical extension, which are benefit to the 570
production transfer from the extensive to the intensive. We find that both off-farm labor weight 571
and off-farm labor index differences between these participants and non-participants are small, the 572
SLCP participants’ and non-participants’ off-farm labor weight increased 30 percentages and 29 573
percentages from 1999 to 2008 respectively; and off-farm labor index increased 1.40 times and 574
1.87 times, which caused the insignificant impact of the SLCP to rural household off-farm income. 575
With regard to the NFPP, table 10 indicates that both land-based intensity index and production 576
expenditure intensity index differences between the NFPP participants and non-NFPP participants 577
are smaller than those differences between the SLCP participants and non-SLCP participants, 578
these both indexes of the NFPP participants are smaller than those non-NFPP participants, for 579
31 / 48
example, the labor intensity index and production expenditure intensity of the NFPP participants 580
are 1.58 and 3.21 in 2008 respectively, these two indexes of non-NFPP participants are 1.93 and 581
4.36 in 2008 respectively (see table 11). These differences of off-farm labor indexes and off-farm 582
labor weights between the NFPP participants and non-NFPP participants are similar to the 583
difference between the SLCP participants and non-SLCP participants, for instance, the off-farm 584
labor weights of the NFPP participants and non-NFPP participants increased 31 percentages and 585
28 percentages from 1998 to 2008 respectively. 586
[Insert table 10 and table 11 here] 587
The impact of the interaction between the NFPP and the SLCP on total income and land-based 588
income has experienced from the insignificant to the significant and positive. The overlap of the 589
SLCP and the NFPP is located in Shaanxi and Sichuan provinces, i.e., Muchuan, Nanbu, Nanjing, 590
Mabian, Yanchang and Zhen’an counties. The government of China decided to permit rural 591
households to cut their trees in the NFPP area in the pilot counties in 2007, rural household could 592
generate some cash income from natural forests. As we discuss above, rural households input their 593
labors and cash for land-based activities. 594
Overall, the contributions of various production inputs and other control variables are in line with 595
our expectations. Notably, labor and production expenditure for land-based activities and off-farm 596
employments have contributed to income growth positively. The government of China has taken 597
some measures to raise rural household income, No. 1 Document of the State Council of China 598
and the Central Committee of Communist of China, to reduce taxation, subsidy and etc., table 5 599
indicates that the dummy variables of the year is positive and significant, and the coefficient has 600
32 / 48
become larger by year. 601
