中国现代化经济体系建设水平时空演进与收敛特征研究
Study on the Spatiotemporal Evolution and Convergence Characteristics of China's Modern Economic System Construction Level
摘要
Abstract
This paper firstly analyzes and constructs the evaluation index system for the construction level of modern econom-ic system from a multi-dimensional perspective,uses the quadratically weighted PCA-EM method to measure the construction level of the modern economic system in 30 provinces of China from 2012 to 2022,then employs the Dagum Gini coefficient and kernel density estimation to analyze the regional differences and evolution trends,and finally adopts the spatial convergence model to analyze its convergence.The results are shown as below:The construction level of China's modern economic system is more po-larized.From the perspective of time,the construction level of modern economic system in each province during the study period has increased but the growth rate is different,but from the spatial point of view,it shows the characteristics of decreasing from east to west,and at the same time,it has strong agglomeration and most provinces are at a low level.Regional differences mainly come from the development differences between the regions,while structural differences mainly come from the development differences of technology-driven,production factors and industrial structure.There is significant β spatial convergence in the construction level of modern economic system.关键词
