以鄱阳湖生态经济区为例,首先基于熵值法建立新型城镇化发展水平评价体系,对2004—2012年该区域内各县区新型城镇化建设进行量化测评.在此基础上进行空间自相关检验,并构建空间面板模型进行计量分析.结果表明:该区域新型城镇化水平具有显著的负空间自相关性,新型城镇化建设表现出显著的空间极化效应,即重点区域、中心城市通过对周边地区资本投资、人才资源、知识的吸引,形成了高速发展、效益良好的新型城镇化发展机制.同时由于过度集中其周边地区的资源和发展条件,在一定程度上影响周边地区新型城镇化进程,导致周边地区城镇化发展水平相对低下,地区之间发展差距持续存在.
Taking Poyang lake ecological economic region as example,we establish a new-type urbanization evaluation index system to evaluate the new-type urbanization level and distribution of the counties in this region from 2004 to 2012,based on entropy method. Then we carry out spatial autocorrelation and build the spatial panel model to make econometric analysis. Results show that there is significant negative spatial autocorrelation in this region,which leads to the significant spatial polarization effect. This effect means that key areas or central cities developed at high speed and in proficient way for the new urbanization,mainly by absorbing capital investment,human resources,and knowledge in nearby regions. This effect has impact on the new urbanization process and the urbanization level of nearby regions. The gap between developed regions and developing regions will still exist in long run.
