经济开放和城乡收入差距的非线性关系：基于省际面板数据的实证研究

经济开放可以通过两个途径影响收入分配：Stolper-Samuelson定理能缩小城乡收入差距而经济开放引致的技术进步效应能扩大城乡收入差距。本文将经济开放分为贸易开放和外资开放,利用我国1995～2005年间省际面板数据对此进行实证研究,发现两者均和城乡收入差距之间存在U型非线性关系。所幸的是我国大多数地区目前仍处在U型关系的左边,因此在我国经济开放能缩小城乡收入差距。

Nonlinear Relationships between Economic Opening and Urban-Rural Income Gaps: An Empirical Research Based on Inter-provincial Panel Data

Economic opening can affect income distribution in two ways： Stolper-Samuelson effect can narrow the urban-rural income gaps and technological progress induced by economic opening can expand the income gaps.In this paper,we divide economic opening into trade opening and foreign capital opening and then do empirical study using inter-provincial panel data,and find that there exists an U-shape nonlinear relationship between China’s economic opening and urban-rural income gaps.Fortunately,most regions in China’s lie in the left side of U-shape,therefore economic opening can narrow China’s urban-rural income gaps.
