Research on the Heterogeneity of Digital Economy Driving Regional Integration Development

Abstract

Based on the panel data of 63 cities in China's Yangtze River Delta, Beijing Tianjin Hebei and Pearl River Delta urban agglomerations from 2011 to 2019, this paper measures the level of digital economy development and regional integration based on relevant theories and practical basis, and tests the impact of digital economy development on regional integration development and its heterogeneity in the three urban agglomerations, Finally, the following conclusions are drawn: ① The development level of digital economy has a significant positive impact on the development level of regional integration of urban agglomeration, that is, promoting the development of digital economy of urban agglomeration is conducive to the integrated development of urban agglomeration. ② There are significant differences in the impact of the digital economy development level of the three urban agglomerations on the regional integration development level of urban agglomerations, showing the phenomenon of Yangtze River Delta > Beijing Tianjin Hebei > Pearl River Delta. Finally, on this basis, the paper puts forward some suggestions on how to use digital economy to drive the development of regional integration.
