长三角地区新质生产力水平测度、时空演化及影响因素分析
Measurement,Spatiotemporal Evolution,and Influencing Factors of New Quality Productivity Level in the Yangtze River Delta Region
摘要
Abstract
New quality productivity is an important focus for realizing high-quality development.This paper measures the new quality productivity level of 41 cities in the Yangtze River Delta region from 2011 to 2022,and analyzes the spatiotemporal evolution characteristics and influencing factors of new quality productivity level by using kernel density estimation,standard de-viation ellipse,Dagum Gini coefficient and its decomposition and spatial econometric models.The study finds that the overall new quality productivity level of the Yangtze River Delta region has significantly increased during the study period,but it is still char-acterized by unevenness and slight multipolarity.In terms of spatial distribution,the new quality productivity level shows a"north-west—southeast"distribution pattern,with a clear characteristic of"strong in the east and weak in the west",and the center of gravity gradually shifting to the southwest.Regional differences are gradually narrowing,especially in Jiangsu Province,where the coordination of regional development is particularly significant.Inter-regional differences are the main source of overall differenc-es,with Anhui Province showing the most prominent disparities with other regions.Population density and industrial structure up-grading significantly contribute to the development of new quality productivity,while urbanization level and foreign trade level have a dampening effect.The new quality productivity has a significant positive spatial spillover effect,and high population densi-ty can positively drive the development of neighboring regions,while the urbanization level and overdependence on foreign trade can inhibit the development of neighboring regions.关键词
