摘要
城乡收入差距问题是影响当前城乡共生性发展的内生性结构障碍,而公共服务的均等化水平又逆向作用于城乡收入差距,因此有效理顺公共服务对城乡收入差距之间的转化效应是实现城乡共生性发展的必要前提。文章通过梳理城乡收入差距的既有文献,建构出公共服务对城乡收入差距的平滑转移模型,借助于阈值协整检验模型,发现公共服务发展水平在不同转移机制水平下其转化效应呈现出差异性。与此同时,通过建构公共服务与城乡收入差距的动态面板模型,利用GMM估计两步法,研究表明了公共服务对城乡收入差距的显著性呈正向转化效应。为此通过相应的政策路径来优化公共服务水平,旨在进一步地缩小城乡收入差距。
Income disparity between urban and rural areas is the endogenous structure obstacles of affecting the symbiotic development of the current urban and rural,and then the equalization level of public services has the adverse effect on the urban-rural income disparity,thus effectively straightening out the transformation effect of public service on the urban-rural income disparity is the necessary premise to achieve symbiotic development between urban and rural areas. The paper reviews the existing literature about the urban-rural incomedisparity,then constructs the smooth transfer model of the public service on urban-rural income disparity. With the aid of the test model of threshold cointegration,this article finds that the transformation effect of development level of public services presents a difference in different level of transfer mechanism. At the same time,by constructing dynamic panel model of the public service and the urban-rural income disparity and using GMM two-step estimation,this article concludes that public service has the significant positively influence on the transformation effect for urban-rural income disparity. To this end,we should make the corresponding path to optimize the public service level,which aims to further narrow the urban-rural income disparity.
