社会资本、非正规金融与农民工自我雇佣

文章基于2009年中国的农村─城镇移民调查数据（RUMIC2009），利用工具变量法克服内生性问题，研究社会资本对农民工自雇选择和自雇收入的影响，并实证检验社会资本对农民工自雇实现的非正规金融支持路径。结果显示：社会资本能够有效促进农民工自我雇佣的实现，这主要是因为社会资本可以为农民工自我雇佣的创立提供部分启动资金，从而在一定程度上缓解其面临的信贷约束，并且社会资本越丰富，农民工自雇初始投资中非正规金融借贷金额越大，比例越高；社会资本对农民工自雇业的后续发展具有积极影响，社会资本存量越大，农民工自我雇佣经营收入越高。

Social capital,non-formal financial and the migrant workers' self-employment

Based on the data from Rural-Urban Migration in China ( RUMIC 2009), and using instrumental variable method to overcome the problem of endogenous, this paper analyze the influence of social capital on the self-employment choice and income of the migrant workers, then empirically examine the non-formal financial supporting path of social capital to the realization of self-employment. The results show that social capital can effectively promote the realization of self-employment of migrant workers, this is mainly because that the social capital can provide the migrant workers'' self-employment with start-up capital, then alleviate the financial constraints to a certain extent, and the self-employed migrant workers who has abundant social capital can receive more non-formal financial credit; social capital has a positive impact on the development of the migrant workers'' self-employment, the greater the social capital amount, the higher the self-employed business income.
