合作社成员资格对农民安全生产行为的影响：来自中国生猪行业的证据【转】

摘要：

本研究利用来自中国主要养猪省份的540名合作社农民和270名非合作农民的家庭调查数据，研究了养猪户参与农民合作社的决定因素、以及农民合作社对采用安全生产实践的养猪户行为的影响。中国养猪生产省份。文章采用倾向得分匹配（PSM）方法来处理由于可观察性而导致的、与农民参与合作社相关的可能的自我选择偏差，并通过敏感性分析进一步补充，以评估PSM结果在不可观测变量存在的情况下的稳健程度。 PSM结果表明，合作社成员对农民采用安全生产实践的倾向值具有显著的、积极的影响，这种影响在一些重要的合作社、农场和家户属性上的是异质的。具体而言，由投资者拥有的公司（IOF）和小规模生产农场领导的合作社的合作社会员效应往往更大。这种影响在以下家户中更大：（1）中等和高等教育水平的家庭（2）不到10年的养猪生产经验（3）没有非农业工作经验（4）专门从事猪的生产。敏感性分析进一步增加了我们对饲料用量和品种使用结果的信心，然而，疫苗接种、药物使用和废物处理结果受不可观察变量的影响更敏感，因此应谨慎解释。

Abstract

This research studies the determinants of pig farmers’ participation in farmers’ cooperatives and the effects of farmers’ cooperatives on pig farmers’ behaviors in adopting safe production practices using data from a household survey of 540 cooperative farmers and 270 non-cooperative farmers from four main pig production provinces in China. The propensity score matching (PSM) method was adopted to deal with possible self-selection bias associated with farmers’ participation in farmers’ cooperatives due to observables, which is further supplemented by a sensitivity analysis to assess the degree to which the PSM results are robust to the presence of unobservables. The PSM results show that the cooperative membership has significant and positive influence on farmers’ propensity to adopt safe production practices and the effects are heterogeneous across a number of key cooperative, farm and household attributes. Specifically, the membership effects tend to be bigger for cooperatives led by Investor-owned firms (IOFs) and farms of small production scale. And the effects tend to be greater for households (1) of medium and high level of education, (2) of less than 10 years of pig production experience, (3) of no off-farm job experience, and (4) that are specialized in pig production. The sensitivity analysis further increases our confidence in the results for the feed use and the breed use, however, the results for vaccination, drug use and waste disposable are more sensitive to the influence of unobservables, therefore should be interpreted with caution.
