本文根据2003--2009午817个样本农户的微观面板数据,首先运用Biprobit模型,识别出了农户租入和租出土地决策的影响因素,解决了以往文献所忽视的内生性问题和“遗漏问题”;然后运用多重内生处理效应模型估计了土地租赁的福利影响,解决了不可观测的变量所导致的自选择性问题,结论表明只要是在自愿基础上所进行的租赁,无论是租出土地还是租入土地,都会增加农户效用,提高农户福利水平。
Using recent survey data of Chinese rural households, this paper identifies the determinants of land rentals and estimates their impacts on households' welfare. We firstly develop a panel biprobit model for the behavior of the tenant and the landlord to deal with the endogeneity issue somewhat ignored by previous research. Then a panel multiple endogenous treatment effect model is estimated to deal with the self-selection problem stemming from unobserved variables. Results show that land rentals have statistically significant and positive effects on households' welfare.
