外商投资与城乡收入差距——基于空间效应视角的分析

Foreign Investment and Urban-Rural Income Gap:An Analysis from the Perspective of Spatial Effect

利用2005—2017年省级面板数据构建空间滞后模型(SLM),分析以外商投资为核心解释变量的多因素对我国城乡收入差距的影响。研究结果表明,外商投资对本地及邻接地区城乡收入差距产生积极作用,对缩小城乡收入差距的边际贡献随经济发展不断递减;人力资本的增长在一定程度上抑制了城乡收入差距的扩大,技术进步、基础设施等变量呈现出显著的地域差异性;本地区城乡收入差距在一定程度上受地理、经济空间相邻地区城乡收入差距的影响,全国和东部地区呈现出示范效应,中西部地区呈现出竞争效应。

This paper constructs a spatial lag model(SLM)by using the provincial panel data from 2005 to 2017 to analyze the impact of multiple factors with foreign investment as the core explanatory variables on the urban-rural income gap in China.The results show that foreign investment has a significant positive effect on the income gap between urban and rural areas in the local and geographical neighboring areas,while its marginal contribution to reducing the urban-rural income gap decreases with economic development.The growth of human capital inhibits the expansion of the income gap between urban and rural areas to a certain extent,and the variables such as technological progress and infrastructure show significant regional differences.The local urban-rural income gap to a certain extent is affected by the urban-rural income gap of the neighboring regions in geographical and economic spaces,the whole country and the eastern region show a demonstration effect,while the central and western regions show a competitive effect.
