我国城乡融合效益及区域发展差异——基于三维均值聚类

Benefits and regional development differences of urban-rural integration in China:Based on three-dimensional mean clustering

城乡融合理念是新时期城乡发展关系的导向,文章借助国家统计局、中国农业年鉴数据库,用主成分分析评估城乡融合效益,用三维聚类及主体效应检验城乡融合差异。研究发现:偏远地区如西藏、青海、宁夏、贵州城乡差异不明显,而广东、江苏、河南等新兴城市城乡发展难以同步。此外政府应当从经济、财政、环境、环保、成本5个维度出发,重视创新创业政策导向,增加补贴力度,鼓励绿色发展。此结论对城乡融合发展效益有待提高的11省极具指导价值,借以提高其政策效率。

The concept of urban-rural integration is the guidance of urban-rural development relations in the new era.With the help of the National Bureau of statistics and the database of China Agricultural Yearbook,this paper uses principal component analysis to evaluate the benefits of urban-rural integration,and uses three-dimensional clustering and subject effect to test the differences of urban-rural integration.The study found that the urban-rural differences in remote areas such as Tibet,Qinghai,Ningxia and Guizhou are not obvious,while the urban-rural development of emerging cities such as Guangdong,Jiangsu and Henan is difficult to synchronize.In addition,the government should carry out reasonable policy guidance from the five dimensions of economy,finance,environment,environmental protection and cost.This conclusion has great guiding value for the 11 provinces whose benefits of urban-rural integrated development need to be improved,so as to improve their policy efficiency.
