森林碳汇项目对欠发达地区农民收入的影响研究——来自四川省5 225个建档立卡户的实证证据

目的 实现欠发达地区农户稳定增收是“后小康”时代巩固脱贫攻坚成果的关键。从微观农户视角评估森林碳汇扶贫项目的增收效应,对于检验项目开发减贫成效、进一步优化项目实施方案具有重要现实意义。方法 文章利用2020年四川省4个森林碳汇项目试点县5 225个建档立卡户的实地调查数据,基于收入结构的视角厘清森林碳汇项目影响农户收入的作用机制,并采用工具变量法进行实证检验。结果 （1）森林碳汇项目对欠发达地区农民具有明显的增收效应;（2）相比建档立卡贫困户,森林碳汇项目对建档立卡脱贫户的增收效应更大,且主要来源于森林抚育环节;（3）森林碳汇项目主要通过林地投入和劳动力投入两种作用机制直接或间接降低建档立卡户财产性收入和经营性收入、增加转移性收入和工资性收入,进而影响其家庭经济收入,但此机制在建档立卡贫困户与建档立卡脱贫户中存在差异。结论 建档立卡脱贫户在森林碳汇项目中,除了能获取碳汇转移性收入,还可凭借劳动禀赋优势获得工资性收入以期弥补财产性和经营性收入损失,进而增加家庭收入;而建档立卡贫困户由于缺乏劳动能力和农业依赖性强,参与森林碳汇项目难以弥补收入损失,最终导致福利受损。这表明后脱贫阶段,森林碳汇项目能够有效促进欠发达地区脱贫户实现稳定增收,充当巩固脱贫攻坚成果的重要工具。     

Poverty decline, agricultural wages, and nonfarm employment in rural India: 1983–2004

We analyze five rounds of National Sample Survey data covering 1983, 1987/1988, 1993/1994, 1999/2000, and 2004/2005 to explore the relationship between rural diversification and poverty. Poverty in rural India has declined at a modest rate during this time period. We provide region-level estimates that illustrate considerable geographic heterogeneity in this progress. Poverty estimates correlate well with region-level NSS data on changes in agricultural wage rates. Agricultural labor remains the preserve of the uneducated and also to a large extent of the scheduled castes and scheduled tribes. We show that while agricultural labor grew as a share of total economic activity over the first four rounds, it had fallen back to the levels observed at the beginning of our survey period by 2004. This all-India trajectory also masks widely varying trends across states. During this period, the rural nonfarm sector has grown modestly, mainly between the last two survey rounds. Regular nonfarm employment remains largely associated with education levels and social status that are rare among the poor. However, casual labor and self-employment in the nonfarm sector reveals greater involvement by disadvantaged groups in 2004 than in the preceding rounds. The implication of this for poverty is not immediately clear—the poor may be pushed into low-return casual nonfarm activities due to lack of opportunities in the agricultural sector rather than being pulled by high returns offered by the nonfarm sector. Econometric estimates reveal that expansion of the nonfarm sector is associated with falling poverty via two routes: a direct impact on poverty that is likely due to a pro-poor marginal incidence of nonfarm employment expansion; and an indirect impact attributable to the positive effect of nonfarm employment growth on agricultural wages. The analysis also confirms the important contribution to rural poverty reduction from agricultural productivity, availability of land, and consumption levels in proximate urban areas.     

Shadow Wages and Shadow Income in Farmers' Labor Supply Functions

This article extends the current literature on estimating the labor supply function in agriculture by providing a different method to derive the shadow wage and shadow income. The method is based on the observation that the shadow wage is the marginal product of labor at the optimal point of both farm and household production functions. Thus, under certain assumptions on the functional form of the production functions, both the shadow wage and shadow income can be derived without estimating the production function. Using a sample of Vietnamese farmers, the results from the new method are shown to be consistent with the theory.     

Did the commodity price spike increase rural poverty? Evidence from a long‐run panel in Bangladesh

We assess the effects of the dramatic rise in agricultural commodity prices during 2007–2008 on income dynamics and poverty among rural households in Bangladesh. A unique panel data set allows us to put the effects of recent events in the context of long‐run trends in income and poverty. We use data from a nationally representative longitudinal survey of rural households in Bangladesh collected in four waves in 1988, 2000, 2004, and 2008. Nargis and Hossain (Nargis, N., Hossain, M., 2006. Income dynamics and pathways out of rural poverty in Bangladesh, 1988–2004. Agric. Econ. 35, 425–435) analysed income dynamics and poverty incidence for the first three waves, finding a declining trend in both the incidence and severity of poverty, aided in particular by human capital development and off‐farm employment opportunities. We update and extend the analysis to include data collected in 2008, at the height of a spike in agricultural prices. We find that the price of a balanced food basket increased by more than 50% during 2000–2008, while household income rose only 15%. As a result the incidence and severity of rural poverty in Bangladesh sunk to pre‐2000 levels during 2004–2008. Thus, the price spikes in 2007–2008 helped push an additional 13 million people into poverty in rural Bangladesh. Moreover, we find that the determinants of poverty have not been time‐invariant. In particular, agricultural production, which had previously been associated with a higher incidence of poverty, served as a hedge against higher food prices during 2004–2008.     

新型城镇化对农民收入的影响效应研究基于30个省（市、自治区）面板数据的实证分析

目的 通过人口的城镇化率、土地的城镇化率、经济的城镇化率、就业的城镇化率这4个自变量综合考察新型城镇化对农民收入的直接影响效应和间接影响效应并提出推进新型城镇化建设促进农民增收的建议。方法 文章运用空间杜宾模型,收集近10年我国30个省（市、自治区,不含港澳台、西藏）的相关数据分析新型城镇化对农民收入的影响。结果 新型城镇化通过人口的城镇化、土地的城镇化、经济的城镇化对农民收入产生显著正向的直接效应,且通过经济的城镇化产生显著负向的间接效应,而就业的城镇化对农民收入影响效应不显著;新型城镇化对农民收入的直接效应主要还是由人口的城镇化产生,但也不能忽视土地城镇化和经济城镇化促进农民增收的作用;控制变量中农业经济水平、农村资本投入、对外开放程度、工业化率对农民收入具有显著正向的直接效应,且农村资本投入对农民收入具有显著正向的间接效应。结论 建议政府大力发展农业现代化,促进城乡一体化;盘活农村土地资源,加快农村城镇化;拓宽农民就业渠道,缩小城乡差别。     

Rising Food Prices and Household Welfare: Evidence from Brazil in 2008

Food price inflation in Brazil in the 12 months to June 2008 was 18%, whereas overall inflation was 7%. Using spatially disaggregated monthly data on consumer prices and two different household surveys, we estimate the welfare consequences of these food price increases, and their distribution across households. Because Brazil is a large food producer, with a predominantly wage‐earning agricultural labour force, our estimates include general equilibrium effects on market and transfer incomes, as well as the standard estimates of changes in consumer surplus. Although the expenditure (or consumer surplus) effects were large, negative and markedly regressive everywhere, estimates of the market‐income effect were positive and progressive, particularly in rural areas. Because of this effect on the rural poor, and of the partial protection afforded by increases in two large social assistance benefits, the overall impact of higher food prices in Brazil was U‐shaped, with middle‐income groups suffering larger proportional losses than the very poor. Nevertheless, as Brazil is 80% urban, higher food prices still led to a greater incidence and depth of poverty at the national level.     

中国农村减贫成效测度、分解及影响因素研究——基于分布动态学框架的CFPS数据分析

测算农村减贫成效并考察减贫成效的影响因素对我国打赢"脱贫攻坚战"具有重要的现实意义。本文基于覆盖我国东、中、西和东北四大地区的CFPS调查数据,在Quah(1997)的分布动态学(Distribution dynamics)基础上构建了完整的减贫成效分析框架。首先测算出各地区农村家庭贫困内部状态的Markov转移概率矩阵,并在此基础上构建了可分解的绝对、相对减贫指数,以综合考察各地区的农村减贫成效,随后本文通过首次构造的"条件Markov模型"进一步考察了减贫成效的影响因素。研究结果发现:(1)样本考察期内,我国各地区的农村贫困状况随着时间的积累逐渐变好,贫困发生率均有所下降;(2)减贫过程中仍存在着脱贫又返贫的现象,农村家庭的深度贫困固化问题比轻度贫困问题更加严重,意味着扶贫开发工作正式进入攻坚时期,扶贫难度加大;(3)家庭成年成员特征、家庭特征以及收入类型对农村减贫成效的影响显著性情况存在着时段和区域的异质性。其中,家庭成年成员受教育水平、家庭中是否有成员从事有薪酬的农业劳动、工资性和营业性收入对家庭的贫困状态变动具有更显著的影响。基于此,政府应贯彻落实精准扶贫,将扶贫重点放在中西部地区和处于深度贫困的家庭,另外应再调整和倾斜扶贫资源与扶贫政策,将提高农民受教育水平、增加非农业就业机会作为主要减贫途径,将促进农村工资性和营业性收入增长作为主要的政策倾斜方向。     

Sectoral and poverty impacts of agricultural policy adjustments in Colombia

We aim to assess the sectoral and poverty impacts of changes in agricultural policy in Colombia. For this, we use an agriculture specialized static computable general equilibrium model, together with a microsimulation model that allows employment to shift between sectors. Results indicate that the sectoral impact from policy changes tends to be small and that it considerably varies across crops. The macro model yields some gains in wages and capital rents, a relatively larger increase in land rents, and limited labor reallocation, together leading to small poverty impacts as calculated through the microsimulation model. The incidence of rural poverty decreases by less than 1% and the same happens to the poverty gap. In addition, poverty reductions are concentrated among households near the middle of the income distribution.     

Are agro-clusters pro-poor? Evidence from Ethiopia

Governments and development agencies increasingly promote agro-clusters as a pathway to improving smallholder incomes and ensuring inclusive rural development through mitigating production and market risks. However, there is very limited empirical evidence to support this promise. We use a large farm household survey of about 4000 smallholder farmers in Ethiopia growing cereals like teff, maize, wheat, maltbarley and sesame to examine the relationship between agro-clusters and smallholder welfare and poverty. Using instrumental variable estimators, we establish a positive association between agro-clusters, household income and per capita income. Agro-clusters are also shown to reduce poverty and poverty gaps. Our results are robust over different agro-cluster proxies and alternative estimators, such as the augmented inverse probability weighting estimator. We also show that our findings are unlikely to be driven by omitted variable bias. Moving beyond average effects and in the interest of understanding heterogeneous effects, we use quantile regressions at different income levels. We find that agro-clusters are associated with welfare gains for all households. However, the most significant gains are observed for the wealthier households. Despite this regressive association, our findings suggest that agro-clusters may be useful in making farming more profitable with significant welfare implications.     

Poverty analysis using small area estimation: an application to conservation agriculture in Uganda

This article demonstrates the utility of small area estimation of poverty (SAEp) methods for researchers wishing to conduct a detailed welfare analysis as part of a larger survey of a small geographic area. This study applies SAEp methods as part of an impact assessment of a conservation agriculture production system in Eastern Uganda. Using SAEp, we estimate Foster–Greer–Thorbecke rural poverty indices, estimate the effects of per‐acre farm profit increases to poor households on the indices, and compare the findings to estimates of net returns from a field‐level evaluation of conservation agriculture for maize farmers. Results suggest that increasing the farm profits of the bottom 30% of households by $1.60 per‐acre per‐season would reduce rural poverty incidence by 1 percentage point. Available data on the net returns to conservation agriculture indicate that even these modest increases are achievable for few adopting households.     

农村金融对减少贫困的作用研究

本文运用2000—2008年我国省级面板数据,检验了农村金融发展对减少农民贫困的作用。研究表明,我国农村金融发展对减少农民贫困的作用,既存在直接效应,也存在间接效应,而间接效应的作用明显高于直接效应。因此,政府在未来制定发展农村金融的政策过程中,应该将重点放在农村金融作用的间接效应上,而不是简单片面地强调直接效应,从而保证农村金融发展能够更加有效地实现减少农村贫困的战略目标。     

China’s Agricultural Policy Transition: Impacts of Recent Reforms and Future Scenarios

This article reviews recent developments in China’s agricultural domestic support policy, especially the transition from taxing farmers and agriculture to providing direct subsidies to grain production and purchased inputs. A model‐based quantitative analysis on the effects of these policy changes is presented. Simulation results suggest that recent policy changes have achieved the declared policy goals of increasing grain production and boosting farm income. Much of the increase in grain production and farm income can be attributed to higher per unit return to arable land, land reallocation to grain production and extra agricultural employment triggered by the policy changes. Based on the assumption that China’s public assistance to agriculture and farmers will continue and rise, two hypothetical future scenarios are simulated. Using all the support permitted under WTO de minimis limits with existing instruments, China’s policy will increase grain production, change trade patterns seemingly contrary to China’s comparative advantage, increase rural employment and significantly increase farm income (by more than 12%). If, however, decoupled instruments are applied to raise China’s agricultural domestic support to the same level, China’s agricultural production and trade will remain unchanged, rural employment remain stable, but farm income will be increased by nearly 15%.     

Pathways out of poverty in lagging regions: evidence from rural western China

How to reduce poverty in lagging regions remains much debated and underserved with solid empirical evidence. This study illustrates an empirical methodology to analyze the pathways households followed out of poverty and to explore their potential in the future using 2000–2004 rural household panel data from two lagging provinces of China, Inner Mongolia and Gansu. It finds that rising labor productivity in agriculture has been key in understanding poverty reduction in rural lagging areas of these provinces and that it still holds much promise. Circular migration has also been important in Gansu, though less so in Inner Mongolia. On average, rural diversification has not proven to contribute much to poverty reduction and income transfers and agricultural tax abolishment have only helped at the margin. The findings from these two case studies highlight that the scope for reducing poverty in rural lagging regions can still be substantial in agriculture, also when nonagriculture drives national growth.     

The effects of a large discrete maize price increase on the distribution of household welfare and poverty in rural Kenya1

This study estimates the effects of a large discrete maize price increase on the welfare of a sample of rural Kenyan households. The usual first‐order welfare approximation formula is extended to a second‐order formula that allows for supply and demand responses to the price change. Results show that many rural households are not affected greatly by the price change, and there are about as many gainers as losers. However, these full sample results mask important differences across regions. Welfare gains generally take place in major production areas while losses are in areas where most households are net buyers of maize. Semiparametric methods are used to investigate the relationship between income and the size of the welfare effect, and poverty dominance techniques are applied to study the impacts of the maize price increase on rural poverty.     

我国农村劳动力的就业意向选择分析——以统筹城乡综合配套改革试验区重庆市为例

农村劳动力的就业意向选择问题研究是对农村富余劳动力转移就业问题研究的进一步深化。该文以统筹城乡综合配套改革试验区重庆农村劳动力资源为主要研究对象,以其当前就业意向性选择为切入点,对影响农村劳动力当前就业意向的不同偏好因素进行分析,对其相关特征变量进行了详细的描述性统计分析,并采用多元Logit模型进行实证分析。研究结果表明,重庆山区农村劳动力当前就业意向存在着明显的性别差异,男性农村劳动力素质总体上优于农村女性劳动力,两者平均年龄仍较高,男性农村劳动力更倾向于外出务工或经商就业,但总体收入仍不理想。务农就业意向的农村劳动力与务工、自主创业或经商就业意向的农村劳动力相比,在年龄、耕地、收入等变量方面存在显著劣势差异。农村劳动力的人力资本、家庭禀赋和所在村劳动力人口数等变量对其不同的就业意向选择具有重要影响和显著差异。     

陕西省农民收入增长问题研究

当前,在我国经济下行压力下,陕西省农民收入增长出现趋缓,收入结构发生较大变化。如何确保农民增收取得新的突破是一个值得研究的重要问题。文章利用文献分析与统计的方法,对陕西农民收入增长情况进行分析,结果显示:2001~2007年农民收入持续增长,2008年后开始回落。而在对农民收入结构特征分析中表明,家庭经营性收入仍是陕西省农民家庭收入的主要来源,但2012年以后有所下降,取而代之的是工资性收入成为农民收入最重要动力因素,农民转移性净收入呈逐年上涨趋势,财产性收入增长幅度波动较大。同时分析目前新常态下影响陕西省农民增收的关键因素,并从大力发展特色农业,建立农业品牌优势;促进农民就业,推动工资性收入增长;加快城乡统筹建设,促进农民转移性收入;深化农村产权改革,推动财产性收入有序增长;提高农村经济质量,完善农民增收长效机制等方面提出了促进农民增收的对策措施。     

How poor are women in rural India?

The assessment of poor women in India as dependent and exploited regardless of poverty focused strategies is reflected in this review of relevant literature. The scholarly approaches to the problems of poor women involve redirection and expansion of resources to women (increase bank credit) through policy and institutional changes, and involve improving women's welfare through changes in class and gender hierarchies; both pertain to restructuring power groups. A little ascribed to belief is that the organization of women's numbers will empower women; the constraints are stated. There is also some argument over whether to design women-specific programs or integrate women into existing programs; some examples are given of successes and difficulties. The regionalization of poverty in eastern and central India is discussed. The growth of the poor has been among the landless, wage-dependent households. 9.6% of households (7.5 million) are headed by women. Women work fewer hours and at lower wage scales and have fewer employment opportunities. Lower earnings are coupled with differentials in demand for female and male labor in agriculture and a crowded labor market. There is a concentration of women in less visible, nonmonetary subsistence production and domestic work. Women are undercounted in employment studies. Women predominate in agricultural activity. Women's status is influenced by economic status, caste, and ethnic background. Domestic work increases status for women and households. The poorer households have greater labor force participation, particularly as wage laborers rather than unpaid family workers. Regional factors affecting rural household strategies are factors affecting the economy (topography, rainfall, climate) and the degree of development, plus sociocultural variables (kinship and religious beliefs which affect the social domain of women), and the degree of dependence on hired vs. family labor. There are sharp contrasts in the value and survival of women regionally. Female labor force participation is low in all regions; the nature and distribution of agricultural laborers is discussed followed by examples from 3 different regions (east, south, and north). The gender inequalities in access to basic needs are reviewed for sex ratio, mortality, and nutrition, and education. The preference is for gender-based policies targeting women.     

The distributional effect of a large rice price increase on welfare and poverty in Bangladesh

This paper studies the distributional effect of a sharp rice price increase on welfare and poverty in Bangladesh. We employ household consumption data and include the indirect effect of price responses to estimate the welfare loss. Our findings suggest that the estimated welfare effect can be misleading if household responses to rice consumption and production are ignored. This study further supports the hypothesis that the poor are the main victims of such a shock. Our examination also indicates that a higher rice price may increase or decrease the poverty head‐count ratio, depending on the choice of the poverty line, but worsens the country's poverty situation when it is measured by the per capita consumption gap. Our analysis reveals that the government can play a central role to prevent and mitigate such shocks, particularly in the medium to long run. On the methodological side, we observe that consumption provides a more consistent outcome across different methods of analysis than household income.     

全面停伐政策对国有林区居民家庭收入的影响

基于2014—2017年对东北、内蒙古国有林区的调研数据,采用双重差分模型(DID)评估全面停伐政策对国有林区居民家庭的人均工资性收入和家庭人均收入的影响。研究结果表明:全面停伐政策的实施对林区居民家庭人均工资性收入和人均收入均存在消极影响;家中有人在其他企事业单位上班有利于促进国有林区居民家庭人均工资性收入和人均收入的增长;从事农林经营不利于国有林区居民家庭人均工资性收入增长,虽然通过获得农林经营收入可以在一定程度上填补工资性收入的减少,但是对家庭人均收入无显著消极影响。因此,建议国家林业与草原局对国有林区居民家庭进行专项资金扶持;转岗分流安排富余劳动力;改变国有林区居民保守的就业观念并鼓励自主创业等。     

Poverty targeting, resource degradation and heterogeneous endowments—a micro-simulation analysis of a less-favored Ethiopian village

Persistent and widespread poverty in less-favored areas (LFAs) is attributed to fragile natural resources and poor markets. Limited assets may keep households outside the reach of poverty policies targeted at LFAs. We explored in a stylized manner the role of heterogeneous household assets for (1) policies aimed at poverty reduction; (2) within-village income inequality; and (3) soil erosion. With a farm-household micro-simulation model we analyzed for each household in a remote Ethiopian village three sets of policies: technology improvement, infrastructure investment, and off-farm employment through migration or cash for work (CFW) programs. Combating poverty with a single policy, migratory off-farm employment reduces the poverty headcount most. Because of self-selection, CFW programs performed best in terms of reaching the poorest of the poor. CFW also reduced within-village income inequality most, while a price band reduction increased income inequality. Only technology improvements resulted in a trade-off between poverty and soil erosion. Price band and off-farm employment policies reduced erosion while outperforming technology improvements in terms of poverty reduction. We found that combining two policies was most helpful in assisting poorer households to overcome the limitations of their asset endowments. A CFW program combined with reduced price bands yielded most in terms of poverty reduction and income inequality. This policy complementarity is, however, less important for better-endowed households. Reducing the reliance of households on agriculture offered a win-win situation of reducing poverty and maintaining natural resources. Combining policies helped to overcome asset limitations, to target policies to the poorest households and to reduce income inequalities.
