中文摘要：

对不完全市场下的农业劳动供给研究,普遍采用不可分性或禀赋依赖假设,即农户的生产决策受消费相关因素的影响,而不是基于利润最大化目标。这种假设只对缺乏非农兼业或市场参与机会的农户成立,故应在决策研究中考虑农户受市场约束的异质性。利用内生选择的切换模型和陕西周至山区的农户调查数据,对农户的非农参与及农业劳动供给决策进行的实证研究表明：金融可及性和人力资本的分布特征决定了农户非农活动的参与及类型,反映了不完全市场对农户的约束状况,进而决定了农业劳动供给决策的影响机制。纯农户的农业劳动供给行为,除了受农户的生计资本影响外,还受其家庭结构等相关因素的影响。

英文摘要：

A number of studies addressed agricultural labor supply based on a separability character assumption,which implies that production decisions cannot be made independently of consumption.In rural China,this separability character only holds for those households who poorly endowed with asset endowments,and therefore unable to participate in non-farm activities. We analyze agricultural labor supply of households based on the assumption of local separability character,using an endogenous switching model and recent data from Zhouzhi.We show that human capital,social capital and financial access have significant but different effects on the agricultural household＇s participation in non-farm activities.Consumption-side variables including household composition have significant effects on agricultural labor supply only for those households unable to participate in non-farm activities.
