中部6省人力资本投入对农民收入的影响力研究

农民收入是区域农村发展水平的重要指标,农村人力资本投入对农民收入增长有明显的促进作用。我国区域农村发展存在东中西差异。中部6省(山西、湖南、湖北、安徽、河南及江西)农民收入水平处于全国中上水平。深入分析中部6省人力资本对农民收入增长的作用,具有重要的现实意义。研究基于1998~2014年的时间序列数据,建立面板数据回归模型,实证分析中部6省人力资本投资对农民人均可支配收入、工资性收入以及家庭经营收入的影响。研究表明:中部6省农村人力资本投资对农民人均可支配收入、工资性收入和家庭经营收入的影响都在1%的水平下影响显著,其中农村人力资本投资对工资性收入的影响效应最大,除山西省外,影响值都达到1.0以上;农村人力资本投资对农民人均可支配收入影响次之,中部6省之间的影响效应值在0.65~0.95之间,山西省影响效应最低;农村人力资本投资对农民家庭经营收入的影响效应值最小,中部6省除山西省外,其他5个省份的影响效应均大于0.5。并提出加大农村人力资本投资,制定人力资本投资向农村倾斜的政策,加大宣传力度鼓励农民进行自主性人力资本投资,以及加大农村医疗基础建设,完善农村医保体系等一系列提高农村居民收入,实现城乡均衡发展的对策建议。     

The impact of soil conservation and output diversification on farm income in Central American hillside farming

This article analyzes the determinants of farm income among hillside farmers participating in natural resource management projects in El Salvador and Honduras. The farm income function was evaluated using a system of equations in which income is determined simultaneously by the farmer's decision to adopt soil conservation technologies and by the level of diversification (number of agricultural activities) on the farm. The database used comes from surveys administered to 678 beneficiaries of these projects during 2002. The econometric results suggest that all the variables related directly to land use (i.e., output diversification, soil conservation practices and structures, and the adoption of forestry systems) have a positive and statistically significant association with farm income. Also, farmers who own land enjoy higher farm incomes than those who do not. The results indicate that when investing in natural resource management projects, governments and multilateral development agencies should pay close attention to output diversification, land tenure, and human capital formation as effective instruments in increasing farm income.     

Farm demand for quality potato seed in Indonesia

Seed is the one of the most costly components of potato production in developing countries. Since potato is a vegetatively reproduced crop, diseases such as viruses build up and yield declines as tubers are saved from one harvest for use as seed the next season. Replacing farm‐saved seed with clean seed is one means to increase yield, but information asymmetry between buyers and sellers on seed quality may restrict market supply of this input. In this article we develop a model of the seed market in which clean seed is treated as a capital good providing benefits over several seasons. To determine farm demand for clean seed, we conducted a survey of 182 potato farmers in the major potato growing areas of Indonesia to elicit their perceptions of seed quality from different sources, and derive farmers' “willingness‐to‐pay” for quality potato seed. Results indicate that the effects of information asymmetry on seed supply may be partially offset by the “reputation” of specialized seed producers. Nevertheless, marginal returns to disease‐free seed appear to significantly exceed marginal costs, indicating that improving supply of quality seed will contribute strongly to productivity growth in potato. We discuss several policy options to encourage supply and utilization of quality potato seed.     

The effect of nonfarm income on investment in Bulgarian family farming

This article documents a relationship between nonfarm income (primarily earnings and pensions) and agricultural investment in Bulgaria, specifically, expenditures on working capital (variable inputs such as feed, seed, and herbicides) and investment in livestock. Among those with positive spending on farm inputs, the estimated elasticity of these expenditures with respect to nonfarm income is 0.14. Nonfarm income also has an effect on the number of households that purchase farm animals, with an estimated elasticity of 0.35. The use of nonfarm income for farm investment is consistent with the presence of credit constraints, as is the fact that less than one percent of farmers report outstanding debts for agricultural purposes. Yet many farm households take out large unsecured loans for other purposes, primarily to cover consumption expenditures, implying that credit is available, but that farmers prefer not to use borrowed funds to finance agricultural investment. This would suggest that increases in the availability of agricultural credit may have little effect on farm outcomes, whereas increases in nondebt-financed sources of liquidity, such as subsidies or transfers, may better stimulate investment.     

SLA框架下生计资本影响山区农户分化的机理与实证研究以广西山区农户为例

目的 基于可持续生计分析（SLA）框架,对生计资本影响山区农户分化进行深入研究,为职业分化背景下促进农户多渠道创收以及实现山区乡村振兴提供参考。方法 文章运用比较分析法、多值选择模型,以广西山区的540家农户为研究对象,探讨农户职业分化的影响因素。结果 研究结果表明,社会资本有助于纯农户与非农农户向以农为主的兼业农户分化;自然资本丰裕更能吸引农户向纯农户或以农为主的兼业分化;增加金融资本有助于兼业农户专注于农业生产,也促使非农经营主体投身于农业经营;物质资本影响农户向纯农户或以非农为主的兼业农户转变;拥有自身务工经历的农民更易于选择以农为主的兼业形态,对农民进行农业技术培训因提升其农业生产经营能力从而有助于他们投身于农业生产;生计资本影响农户分化的程度因距离中心市场的远近而存在差异。结论 生计资本影响农户向不同类型的职业进行分化,应从鼓励农户兼业化实现收入多元化以及鼓励乡村精英返乡创业的视角,适应不同类型农户分化需要,为调整农户生计资本,维持生计可持续性提供必要的决策支持和政策保障。     

The Diversity of Farmers' Risk Management Strategies in a Deregulated New Zealand Environment

In this paper, the results of a nation-wide survey of New Zealand sheep and beef farmers are presented. Multivariate statistical techniques are used to identify groups of farmers who differ in their risk management practices. Five groups are identified. They are labelled income risk reducers, capital managers, part-timers, debt and market risk managers, and production managers. These groups differ in their perceptions of risk sources and in some farm and farmer characteristics. Reasons for these differences are identified and discussed in the context of deregulation.

Agricultural diversification and integrated pest management in Bangladesh

We study factors associated with a shift toward diversified, high‐valued vegetable crops and the incentives associated with the use of IPM methods for vegetable producers in Bangladesh. The primary objective is to measure how IPM technologies affect the crop and technology choices of low‐income rice farmers. A three‐season household optimisation model is used to study crop and technology choice under price and yield uncertainty. The model is parameterised using data from vegetable farms and experimental IPM trials conducted in Bangladesh. Simulation results show that access to IPM technology and IPM availability combined with access to credit increase household welfare and lead to higher rates of vegetable adoption. Off‐farm employment opportunities work against vegetable cultivation and IPM use by risk‐averse farmers. Implications for policy and extension efforts are highlighted.     

Effects of European Union agricultural policies on the sustainability of grazingland use in a typical Greek rural area

Recent changes in the Common Agricultural Policy (CAP) introduced different definitions regarding the eligibility of various types of land used by grazing animals. In particular, shrublands and other low-quality areas which have traditionally been used as grazinglands are now not eligible for European Union income support payments. Subject to these changes, a large part of livestock farms will be affected, being partially or fully deprived of EU income support. In addition to these policy-driven changes, pasture-fed livestock farms in Greece are faced with a unique system of grazingland allocation, as all grazing areas in the country are state-owned. These areas are allocated for a short period either directly to farmers who are permanent residents of the Municipalities or to other livestock farmers through an auction system, which does not take into account the grazing capacity thus bringing about environmental degradation. This paper investigates the effects of CAP changes and of this communal land allocation system based on the findings of a typological analysis. The study focuses on a typical Greek territory in terms of land uses, economic activities and sociodemographic developments. Data from a questionnaire survey are used to build a typology of local livestock farms in terms of their nutritional management and land use characteristics and then the profile of each type is investigated through the estimation of a Multinomial Logit Model where the dependent variable is the cluster participation. Three distinct types of farms (clusters) are determined. Cluster 1 includes traditional farms which rear sheep and goats and bovine for meat, which are highly dependent on grazingland uses and EU income support. Cluster 2 farms – mainly sheep and goat – have evolved a ‘double’ dependency on land in the form of grazingland but also of cropland for feedstuff production, which renders them more resilient to policy changes. Finally, Cluster 3 farms are intensive dairy cattle farms and use artificial (cultivated) privately-owned grazinglands and cropland for feedstuff production. Market-oriented measures are proposed for each type and suggestions for an integrated land use plan are made, including long-term leasing of land and the consideration of environmental criteria for land allocation, thus rendering farmers responsible for keeping their land in a good production state.     

Taxation, life-time uncertainty and non-industrial private forest-owner's decision-making

The nonindustrial private forest (NIPF) owner's consumption and harvesting decisions are investigated under inheritance and capital income taxes using a two-period model. The impact of the forest-owner's age is introduced into the analysis through a parameter of perceived probability of surviving through a future period. This allows us to study the impacts of ageing on consumption and harvesting decisions as well as to see how the impact of taxes changes among different age groups of forest-owners. The results show that current consumption first decreases and then increases when moving from younger to older individuals regardless of whether non-timber assets are more or less heavily taxed through bequests than consumption. In general, we find that tax effects are dependent on the forest-owner's age. Age tends to intensify the increasing effect of the forest bequest tax on harvesting. The same is true with respect to the decreasing effect on harvesting of the inheritance tax imposed on non-forest assets. Furthermore, the forest-owner's age tends to intensify the effect on harvesting of the capital income tax imposed on forest assets, but diminishes the effect on harvesting of the capital income tax imposed on non-forest assets.     

EU Food Safety Standards,Pesticide Use and Farm‐level Productivity: The Case of High‐value Crops in Kenya

This article provides an empirical analysis of the impact of European Union (EU) private food safety standards on pesticide use and farm‐level productivity among small‐scale vegetable producers in Kenya. We apply an extended three‐stage damage control production framework, accounting for multiple endogeneity problems, to farm‐level data collected from a random cross‐sectional sample of 539 small‐scale producers. Estimation results show that farmers producing vegetables for the domestic market use significantly lower quantities of pesticides than do export farmers. However, contrary to findings elsewhere, the econometric evidence here shows that both domestic and export‐oriented vegetable farmers in Kenya use pesticides at levels below the economic optimum. The results also show that the adoption of standards by export farmers does not have any significant impact on total pesticide use. However, adopter categories are distinguishable in terms of types of pesticide used, i.e. adopters use safer pesticides based on World Health Organization (WHO) classification. The third‐stage structural revenue model results demonstrate that adoption of standards has a positive and significant impact on revenue raised in vegetable production. Nevertheless, farmers producing for the export market are indistinguishable from those producing for the domestic farmers in terms of the total revenue earned from producing vegetables during the rainy season, on a ‘per acre’ basis. Although standards can potentially prevent resource‐poor smallholders from maintaining their position in the lucrative export markets, they can also result in positive changes in the production systems of those small‐scale farmers who adopt it, as shown by these results.     

新疆农业资金投入与农民收入效应关系的实证研究

[目的]为清晰识别农业资金投入对新疆农民收入的影响程度,并给予地方政府进一步优化调整农业资金使用效能提供参考依据。[方法]文章选取1978~2013年新疆统计数据,采用协整分析、误差修正模型等方法对财政支农、农业贷款、农民自主投资与新疆农民人均纯收入进行了实证探究。[结果]新疆地区财政支农、农业信贷、农民自主投资与农民人均纯收入之间存在长期均衡关系;而短期内财政支农、农业信贷以及农户自主投资的促进效应不如长期明显,其中农业贷款的收入效应远低于财政支农和农民自主投资;财政支农、农民自主投资与农民人均纯收入在短期内具有格兰杰因果关系,长期则格兰杰因果关系解释力逐渐减弱,而农业贷款在短期内不是新疆农民人均纯收入增长的格兰杰原因,长期则互为格兰杰因果关系。[结论]该文提出加大财政支农投入力度,提高财政资金配置效率;推动农村金融改革,提高农村金融效率;提振农民自主积累资金投资的积极性等政策含义,以期为新疆"三农问题"有效解决提供坚实可靠的资本基础。     

Assessing the Impact of Alternative Water Pricing Schemes on Income Distribution

The reform of water pricing policies may represent an effective instrument for enhancing the efficient use of water resource. However, policy makers fear that a change in the pricing methods may cause income loss for some farmers, and that this income inequality may generate public discontent and policy inertia. The aim of this paper was to compare some pricing methods in order to measure their effects on income distribution. The analysis focuses on the income distribution among different types of farms, and the income distribution between different social groups (landowners, capitalists and workers) in the short term. A linear programing model based on expected utility theory is used to take into account the effect of commodity prices and rainfall variability, which are among the most relevant factors affecting farmers’ income. According to the findings, water pricing schemes do not affect the income distribution among farm types, although a significant impact emerges on the distribution among social groups, and in particular on the wages of temporary workers.     

Farmers’ Income and Production Responses to Rural Taxation Reform in Three Regions in China

The relationship between agricultural taxation and production efficiency has been thoroughly explored for many countries. Recently, China has taken various measures including the rural taxation reform (RTR) to promote grain production and to increase farmer incomes. In this study, we investigate whether the Chinese policy of abolishing rural taxation has improved farm households’ incomes and affected their production decisions. Using household survey data obtained from three regions in China, we estimate the effect of the RTR on farmers’ income. Results show that the RTR has significantly improved farmers’ post‐tax net income by 9.2% in Shandong, 16.9% in Shanxi and 16.8% in Zhejiang. These increments, mostly from farm income rather than from off‐farm income, are much higher than the direct income increase from the tax savings. In addition, we examine the dynamic impact of farmers’ net income, and find that the RTR has a sustained positive income effect in Shandong and Shanxi, whereas its positive effect in Zhejiang appears temporary. We also examine farmers’ production responses to the RTR. Results show that farmers in the three regions respond in different ways: farmers in Shandong significantly increase their labour input, farmers in Zhejiang increase intermediate inputs, whereas Shanxi farmers augment their intermediate inputs and enlarge their crop acreage. It appears that the farmers’ responses to the taxation reform vary due to the agronomic and economic factors in these three regions, suggesting that diverse post‐RTR supplemental policies should be implemented in different regions.     

气候变化对农户的经济影响研究——基于南疆红枣主产区农户收入安全视角

气候对农户的影响存在于以农户为中心的两阶段价值链(生产和产后环节)中,农户收入是气候直接影响和农户为规避气候风险调整生产经营行为的结果。基于阿克苏地区2011~2014年316户枣农微观面板数据,在Ricardian模型理论基础上提出气候-两阶段影响模型,运用考虑气候影响的随机系数模型,构建全要素适应性生产函数模型。研究表明:4~8月生长期和9~10月成熟期气温升高对农户增加收入有利,但农户对极端高温的适应能力不足;4~8月主产区降水增加对农户的影响利大于弊,9~10月成熟期降水增加使农户不可避免陷入由气候导致的市场风险;生产阶段气温升高使肥料的产出弹性下降,降水增加使肥料的产出弹性上升,农药的产出弹性下降,气候变化导致农业成本增加,农户适应气候变化的农业调整行为不科学。为保证农户收入安全,农户在生产和产后阶段气候适应能力亟待提高,尤其应充分考虑产后阶段的气候适应性措施。     

Evaluation of drought management in irrigated areas

This paper focuses on the economic consequences of droughts for the irrigation sector. We develop a dynamic‐recursive mathematical programming farm model that assumes imperfect mobility of capital and labour as well as rational expectations about future water availability. The model is calibrated to 12 representative farms belonging to three irrigation communities of the Guadalquivir Basin (south Spain) and used to simulate the 1991–1997 period, which included 3 years of intense drought. Results indicate that the drought imposed significant costs on farmers, but show also that water managers partly exacerbated these costs by allocating excessive amounts of water to irrigators in the abundant years. The model is also used to evaluate the benefits of a perfect water supply forecast and to simulate the economic gains of a voluntary water banking scheme. Results show that the benefits resulting from the perfect forecast of water supply 1 year ahead would represent a relative gain of 5%. However, a voluntary banking system would allow farmers to increase their benefits by 32–82% depending on the supply system.     

The role of agricultural entrepreneurship in Dutch agriculture of today

It is thought that agricultural entrepreneurs have an important role to play in Dutch agriculture. They are currently being confronted with drastic changes and it is open to question whether or not they are willing and able to deal with such changes. A telephone survey was carried out in order to find an answer to this question. The data presented here are based on the answers from 752 farmers. The questions to be answered were: (1) Which strategies do agricultural entrepreneurs choose to keep up with business demands? (2) Which personal characteristics are related to these choices and to successful agricultural entrepreneurship in general? (3) Do agricultural entrepreneurs in the Netherlands meet the demands of “real” entrepreneurship according to economic theories? Agricultural entrepreneurship was conceptualized into the strategic orientations, social orientation, growth orientation, and financial conservatism. The data showed that five different types of farmers could be distinguished on the basis of their preferences for different strategic orientations. Social farmers had especially high scores for social orientation, traditional growers for growth orientation, prudent farmers for financial conservatism, new growers for both social orientation and growth orientation, and indecisive farmers for all strategic orientations. The latter group was eliminated from the data because farmers in this group had the highest scores for almost all items of the questionnaire, whether or not these concerned positive or negative aspects of entrepreneurship. Moreover, they gave contradictory answers to comparable questions. Based on future expectations and family income, it was concluded that social farmers and new growers were more successful than other farmers. According to economic theories, they also seemed to meet the “demands” of “real” entrepreneurship better than other farmers because they can be called “movers of the market,”“innovators,” and/or “discoverers of profit opportunities.” New growers and social farmers were also distinguishable from the other groups of farmers by their personal characteristics. In general, it could be concluded that positive personal characteristics (self‐criticism, leadership, creativity, perseverance, and initiative) affected agricultural entrepreneurship positively, and negative personal characteristics (love of ease and passivity) affected it negatively.     

The wealth of nature: economics as if survival mattered

Livestock play a key role in the lives of poor, rural people in developing countries, providing a major proportion of their cash income, capital assets, draught power, fuel and fertilizer. Rapid growth in demand for meat and dairy products in Asia presents both opportunities and challenges for livestock development and poverty alleviation. This paper explores the potential of livestock intensification to benefit the livelihoods of upland households and meet market demand in the Lao Peoples' Democratic Republic (Lao PDR), a South East Asian country undergoing significant economic change.

A review of the livestock sector in Asia shows increasing demand for live animals and meat in neighbouring Vietnam, Thailand and China. Lao PDR is well positioned to capitalize on the growing Asian livestock sector, however the extent livestock production in Lao PDR can reduce poverty, meet growing domestic meat demand and lift livestock exports is problematic. Findings from research in two upland northern provinces demonstrate how the introduction of forages for livestock has revolutionized the lives of some farmers and villages, but concludes that strategies are still needed to engage poorer households. The impacts of changing domestic and export markets are less certain, and are discussed within the context of environmental and public health, cultural traditions, economic development and sustainable livelihoods.
