摘要基于山东省果蔬种植户的实地调查数据,采用内生转换回归模型(ESR)与因果中介分析模型(CMA),从社会化服务供给异质性视角检验了参加合作社对农户家庭务农收入的影响效果及作用机理。结果表明:参加合作社具有明显的促农增收效应;合作社的社会化服务有效供给对成员家庭务农收入的提升存在显著的因果中介效应,其中金融信贷服务、技术培训服务和生产流程服务对成员家庭务农收入提升的平均因果中介效应依次递增;尚无证据表明产品销售服务对成员务农收入存在显著影响。因此,在引导和鼓励农户加入合作社的同时,应重视强化合作社的社会化服务功能,适度扩大合作社的社会化服务供给规模。 The participation of small farmers in cooperatives and how to increase their income effectively have always been the focus of debate among researchers of cooperative economy.Based on the field survey data of 1,127 fruit and vegetable growers in Shandong Province,the endogenous switching regression(ESR)model and the causal mediation analysis(CMA)model are adopted to empirically test the influential effect of participating in cooperatives on the farming income of farmers from the perspective of socialized service supply heterogeneity and the action mechanism.The empirical results indicate that participation in cooperatives has a significant effect of promoting increase in farmers’income,and the farmers who actually participate in cooperatives increase their household farming income compared to the estimated income if they did not participate in cooperatives;the effective supply of cooperative’s socialized services has significant causal mediation effect on the increase in the household farming income of members,wherein the average causal mediation effects of financial credit services,technical training services and production process services on the increase in the household farming income of members progressively ascend;and there is no evidence suggesting that product sales services have a significant impact on the farming income of members.Consequently,while guiding and encouraging farmers to join cooperatives,the socialized service functions of cooperatives should be valued,and the socialized service supply scale of cooperatives should be appropriately expanded.
