城市新质生产力的时空演变格局及收敛性分析
Spatiotemporal Evolution Patterns and Convergence Analysis of Urban New Quality Productivity
摘要
Abstract
Based on the theoretical analysis of urban new quality productivity in China,a comprehensive evaluation index system constructed from three dimensions of laborers,la-bor objects,and means of labor was proposed.Panel data from 260 prefecture-level cities in China from 2011 to 2021 were analyzed using methods such as the entropy method,Markov chains,and spatial β-convergence to evaluate the development level and dynamic evolution of new quality productivity.Results show that the spatial Markov transition probability matrix reveals the stability of transitions between different types of new quality productivity in China,along with the phenomenon of"club convergence".Geographic con-texts play a significant role in type transitions of new quality productivity.From the per-spective of long-term evolution trends,the future development prospects for new quality productivity in China appear optimistic,with a tendency toward a concentration in high-value regions.At both the national and regional levels,spatial absolute β-convergence and spatial conditional β-convergence were observed.In the central region,spatial effects var-ied under the influence of control variables,including urbanization rate,openness to the outside world,infrastructure,and government intervention.关键词
