利用空间自相关模型和非嵌套空间权值矩阵的检验方法,以长三角、珠三角、环渤海经济区作为研究对象,对区域经济增长过程中的城市化效应及经济的集聚与扩散所产生的空间结构进行了分析。研究结果表明,三大区域存在各自独特的空间结构特征和城市化进程道路,应继续提升城市集中度,通过发展中心城市缩小区域内收入差距,带动整个区域协调发展。其中珠三角地区已达到城市最优集中度,应通过扩张区域辐射范围来均衡区域的最优城市集中度。
Taking the spatial autocorrelation model and the test method of non-nested space weight matrix as the research object, this paper takes the Yangtze River Delta, Pearl River Delta and Bohai Rim Economic Region as the research object, and analyzes the urbanization effect and economic agglomeration and diffusion in the process of regional economic growth The spatial structure of the analysis. The results show that there are unique spatial structure features and urbanization path in the three major regions. Urban concentration should continue to be enhanced. The development of central cities should narrow the income gap and promote the coordinated development of the entire region. Among them, the Pearl River Delta region has reached the optimal urban concentration, and the optimal urban concentration in the region should be balanced by expanding the regional radiation range.
