摘　　要：本文选取新疆棉花种植户数据,综合采用平均处理效应模型、多重处理效应模型和分位数处理效应模型等方法,考察加入合作社对农户收入的影响、异质性及其作用机制。本文主要有如下发现:①加入合作社对农户有增收作用,平均意义而言,加入合作社相对于未加入合作社使得农户收入增长约23%。②合作社不同参与方式对农户增收的影响存在差异,相对于未参与合作社,消极参与、松散参与和紧密参与对农户的增收作用不断提升,即参与程度越深增收效应越明显。③合作社的增收效应随着分位数的提高而提高,即加入合作社实质上对高收入农户的增收作用最明显。④合作社通过提升农户的生产效率、交易效率、议价能力和自信水平,进而对农户增收产生积极作用。Based on the data of cotton farmers in Xinjiang province,this paper uses the average processing effect model,multiple processing effect model and quantile processing effect model to investigate the impact,heterogeneity and mechanism of joining cooperatives on farmers’income,and effectively solves the endogenous estimation error caused by the sample selection problem which is often ignored in previous studies.The main findings of this paper are as follows:①Joining cooperatives can increase the income of farmers.On average,joining cooperatives can increase the income by about 23%compared with not joining cooperatives.②Different ways of participation of cooperatives have different effects on the income of farmers.Compared with non-participating cooperatives,negative participation,loose participation and close participation have different effects on the income of farmers The effect of increasing income is increasing,that is,the deeper the degree of participation is,the more obvious the effect of increasing income is.③The effect of increasing income of cooperatives increases with the increase of quantile,that is,joining cooperatives has the most obvious effect on increasing income of high-income farmers.④Cooperatives can improve farmers’production efficiency,transaction efficiency,bargaining power and self-confidence by improving farmers’production efficiency,transaction efficiency and self-confidence.Confidence has a positive effect on the increase of farmers’income.
