新质生产力发展水平、空间差异及动态演进OA北大核心CHSSCDCSSCICSTPCD

Based on the characteristics of high-tech,high efficiency and high quality of new-quality productivity,this paper constructs an evaluation index system including 3 first-level indicators,9 second-level indicators and 32 third-level indicators,then uses the entropy weight method to measure the development level of new quality productivity in China from 2012 to 2022,and finally adopts the Dagum Gini coefficient,Moran's index and kernel density function for classification measurement.The results are shown as follows:From the perspective of development level,the development level of China's new-quality productivity shows a steady upward trend,and the regional development level of new-quality productivity presents an"east>central region>north>west"pattern.From the perspective of spatial difference,the overall difference of new-quality productivity development level shows a trend of steady expansion,and the inter-regional difference is the main cause of the overall difference,and the inter-re-gional difference presents an"east-west>east-north>middle-west>middle-north>east-middle"unbalanced spatial pattern.From the perspective of dynamic evolution,the development level of new-quality productivity has a significant spatial positive cor-relation,and shows a downward trend.The results of kernel density estimation show that the national new-quality productivity lev-el is constantly improving and its difference shows a trend of dynamic expansion.
