Regional Differences and Dynamic Evolution of New Quality Productivity Development Based on Watershed Perspective
In order to provide a basis for regional layout and development of new quality productivity according to local conditions,and for-mulate targeted policies for coordinated development of new quality productivity,a comprehensive index system reflecting the development level of new quality productivity was built based on the three dimensions of new types of workers,new types of labor materials and new types of labor objects.From the perspective of river basin,using the relevant data of 21 provinces(municipalities and autonomous regions)from 2015 to 2022,the entropy weight method,Dagum Gini coefficient and its decomposition method,and kernel density estimation method were used to empirically investigate the development level,regional differences and dynamic evolution trend of new quality productivity in the Yan-gtze River,Yellow River and Pearl River basins.The results show that a)in terms of spatial-temporal distribution,the development level of new quality productivity is on the rise as a whole,and the development level of new quality productivity and its components in the Yangtze River Basin is in the leading position,the Pearl River Basin is in the middle level and the Yellow River Basin is at the lowest level;b)In terms of regional differences,the internal differences of new quality productivity in the Yangtze River Basin are the smallest,the internal differences in the Pearl River Basin are the largest,and the differences between groups in the Yellow River basin and the Yangtze River basin are the largest,which is the main source of the overall differences of new quality productivity in the three major basins;c)In terms of dy-namic evolution,the intra-regional gap of the development level of new quality productivity in the three major river basins shows a weakening trend,especially in the Yangtze River Basin,the unbalanced development of new quality productivity in the Pearl River Basin is more promi-nent,and the unbalanced development of the Yellow River Basin has shown a weakening trend,but the overall development level is at a rela-tively low level,and the task of developing new quality productivity is even more arduous.
