基于北京大学国家发展研究院的"中国农村金融调查"专项入户调研数据,运用Biprobit模型和SEM模型,研究基于业缘、血缘和地缘的农民合作社形成的社会网络对农户正式与非正式融资的影响。结果发现,农民合作社对农户正规与非正规融资均有显著正向影响。说明农业合作社作为一种新型的农业组织制度,不仅在促进农业现代化方面发挥了重要作用,而且在村级社会网络的形成和村级信用体系建设方面也有一定的影响。这表明,充分发挥农民合作社形成的社会网络在农村金融市场中的作用,对进一步深化农村金融体系改革具有一定的意义。
Using data from rural China collected by National School of Development at Peking University( NSD),this paper examines the hypotheses that the higher probability of formal and informal finance for farmer household is due to the higher existence of farmer cooperatives' social network. With Bi-probit Model and Simultaneous Equation Model,our key finds are that cooperatives' social network has positive and significant effect on farmer household's formal and informal finance,and those finds are independent of endogenous effect. This indicates that without a sophisticated credit system in rural China,cooperatives' social network plays important role on informal and formal finance qualification for farmer household,meanwhile,farmer cooperatives also play a complementary role on village( community) credit system construction. Our findings contribute to the further reform of rural finance system.
