通过构建一个相对完整的分析框架,区分农地产权的两种效应——生产率改进效应和劳动力转移成本降低效应,分析其对农业-非农劳动力转移的影响机制,以及最终如何影响城乡收入差距。数值模拟结果显示:农地产权强化未必能促进劳动力由农业向非农部门转移,但是能够带来城乡收入差距的缩小;如果城乡的资产分配状况不改善,仅仅依靠劳动力流动,城乡收入差距难以有较大改观。分别运用RUMi C微观调研数据和省级面板数据进行实证分析,试图检验农地"大调整"和"小调整"对家庭非农劳动参与的影响以及省级层面的征地补偿费用(指代农地产权状况)和城乡收入差距之间的联系,结果倾向于支持强化农地产权能够促进城乡收入差距的缩小(尽管作用有限),并且征地补偿费用越高的地区往往城乡收入差距越小。
In a formulation based on the classic C- D production function,this paper assumes two channels that how the strength of farmland property rights affects rural labor migration and urban- rural income gap,productivity improvement and migration cost reduction. Numerical simulation indicates that strengthening farmland property rights does not necessarily induce labor migration from agricultural to non-agricultural sectors,but urban- rural income gap is narrow ed. Urban and rural income doesn' t converge if the inequality of wealth distribution remains unchanged between urban and rural residents. Utilizing RUM i C survey data and provincial statistics,the paper examines how the adjustment of farmland impacts household non- farm work participation and relationship of the compensation of farmland acquisition( a proxy for farmland property rights) and urban- rural income gap among provinces. The results tend to support the narrow ing,but limited,effects of farmland property rights on urban- rural income gap. Provinces that have more generous compensation tend to have narrower income gap between urban and rural areas.
