摘要
新质生产力是由生产要素创新性配置而产生的先进生产力,对推动我国经济社会发展具有重要意义。文章基于新质生产力三要素构建综合评价指标体系,通过熵值法测算2005—2022年我国十大城市群新质生产力水平,并运用Dagum基尼系数及其分解、核密度估计、马尔可夫链、空间收敛模型等方法考察城市群新质生产力水平的区域差异、动态演进特征及空间收敛性。研究结果表明:第一,在考察期内,我国城市群新质生产力水平呈现上升趋势,且表现为阶梯型分布特征;从三大维度指数看,劳动对象发展指数最小。第二,我国城市群新质生产力水平总体差异以年均2.26%的速度持续上升,区域内差异与区域间差异均呈现扩大态势,超变密度是总体差异的主要来源。第三,我国城市群新质生产力水平存在空间多极化特征,且“俱乐部趋同”现象明显。第四,我国城市群新质生产力水平存在显著的空间收敛性,不同城市群间存在明显的“追赶效应”。
New quality productivity is an advanced productivity generated by innovative allocation of production factors,which is of great significance in promoting China’s economic and social development.This paper constructs a comprehensive evaluation index system based on the three major elements of new quality productivity,and calculates the level of new quality productivity of the top ten urban agglomerations in China from 2005 to 2022 through the entropy method.The Dagum Gini coefficient and its decomposition,kernel density estimation,Markov chain,spatial convergence model,and other methods are used to examine the regional differences,dynamic evolution characteristics,and spatial convergence of new quality productivity level in urban agglomerations.The research results go as below:Firstly,the new quality productivity of urban agglomerations in China is showing an upward trend during the study period,characterized by a stepped distribution,with the labor object development index being the smallest among the three dimensions.Secondly,the overall differences in new quality productivity level among urban agglomerations in China has been continuously rising at an average annual rate of 2.26%,with both intra-regional and inter-regional differences showing an expanding trend.The super variable density is the main source of the overall differences.Thirdly,the new quality productivity level in China’s urban agglomerations exhibits spatial multi-polarity characteristics,and the phenomenon of“club convergence”is evident.Fourthly,there is a significant spatial convergence in the level of new quality productivity in China’s urban agglomerations,and there is an obvious“catch-up effect”among different urban agglomerations.
