长江经济带社会经济保障的测度、区域差异与障碍因子

Measurement,Regional Differences,and Obstacle Factors of Social and Economic Security in the Yangtze River Economic Belt

提升社会经济保障水平是社会经济发展的主要目标。文章立足社会经济保障水平测度体系,运用熵值法测度“十三五”时期长江经济带的社会经济保障水平,引入Dagum基尼系数、Moran′s I指数、障碍度模型考察区域差异、空间相关性和障碍因子。研究发现:长江经济带11个省市的社会经济保障发展程度偏低,72.73%的省市处于较低或极低水平;长江经济带社会经济保障的总体差异主要源于区域间差异,并呈现“中心—外围—边缘”的圈层扩散分布格局;最主要的障碍因子是居民生活。“十四五”时期长江经济带应加速推进高质量一体化,以核心城市为中心形成空间辐射效应,实施个性化社会经济保障战略。

Improving the level of social and economic security is the main goal of social and economic development.This paper is based on the measurement system of social and economic security level,using the entropy method to measure the social and economic security level of the Yangtze River Economic Belt during the"13th Five-Year Plan"period.The Dagum Gini coefficient,Moran′s I index,and obstacle model are introduced to examine regional differences,spatial correlations,and obstacle factors.It has found that the level of social and economic security development in 11 provinces and cities in the Yangtze River Economic Belt is relatively low,with 72.73%of provinces and cities at a low or extremely low level.The overall difference in social and economic security in the Yangtze River Economic Belt mainly stems from regional differences,and presents a“center-periphery-edge”circular diffusion distribution pattern.The main obstacle factor is residents′daily life.During the"14th Five-Year Plan"period,the Yangtze River Economic Belt should accelerate the promotion of high-quality integration,form a spatial radiation effect centered on core cities,and implement a personalized social and economic security strategy.
