摘　　要：经济理论表明分工与合作对农户收入增加有重要作用,但农户在参与农业分工和加入农民合作社时存在自选择行为,不考虑这一行为引起的内生性,会造成最小二乘法的过度估计.利用2010年中国6省农户的微观调查数据,建立Treatment Effects模型分析了分工与合作对农户农业收入的影响,估计结果表明,在处理了自选择行为产生的内生性问题之后,农户参与农业分工、加入农民合作社对农户的农业收入有显著的正向影响.Economic theory points out that division of labor and cooperation play an important role in farmers＇ income growth. However, the self-selection behavior of the farmers in their participating in agri- culture division of labor and joining farmers＇ cooperatives, which fails to consider its endogeneity, will lead to an over-estimation of the least squares method. Based on the survey data of 2010 from 6 provinces in China, this paper establishes a ＂treatment effects model＂ to estimate the impact of division of labor and co- operative on farmers＇ agricultural income. The results show that farmers＇ participation in agricultural divi- sion of labor and joining farmers＇ cooperatives have a significant positive influence on farmers＇ agricultural income when they take into consideration the endogeneity of self-selection behavior.
