Abstract

With the rapid development of IT, the digital economy has become a key driver of global growth, changing traditional models via advanced tech. Using 2013 - 2022 data of 30 Chinese provinces, this study constructs index systems by entropy weight CRITIC - TOPSIS and projection pursuit model. It analyzes spatio - temporal evolution through kernel density estimation, Moran's index and Dagum Gini coefficient decomposition. A two - way fixed effects panel data model tests the digital economy's empowerment mechanism. Results show new quality productivity grows but with regional differences, spatial agglomeration exists, and the digital economy has a positive impact, emphasizing its role in reducing disparities and promoting growth.
