A Study on the Provincial Distribution Characteristics of New-Quality Productivity in China

This study constructs an evaluation index system for new-quality productivity and employs the entropy method to measure the levels of new-quality productivity in 30 Chinese provinces from 2012 to 2022. Additionally, it analyzes the provincial distribution characteristics using the Dagum Gini coefficient decomposition method. The results show that the new-quality productivity in the eastern region is significantly higher than that in the central and western regions. Regional differences are primarily due to inter-regional disparities, but the overall trend is towards convergence. The β-convergence analysis indicates that there is no β-convergence phenomenon of new-quality productivity among Chinese provinces. The development speed of low-level regions is lower than that of high-level regions, leading to a continuous expansion of regional differences. This study provides theoretical basis and empirical references for formulating policies on regional coordinated development and high-quality economic growth.
