Does Construction of Urban Agglomeration Promote the Development of Digital Economy?
Digital transformation is an important aspect of the development of new quality productive forces.Based on the new characteristics and trends in China's regional and industrial development,this article focuses on the impact of urban agglomeration construction on the development of the digital economy.With the continuous advancement of urbanization,the characteristics of cross-regional flow of factors are constantly strengthened,the exchanges and connections between cities are becoming increasingly close,and urban agglomerations are gradually becoming the main spatial carriers for regional economic development in China.By strengthening resource and market sharing,knowledge and technology spillovers,and factor and enterprise matching on a larger scale,urban agglomerations can expand economic space to form stronger agglomeration and network externalities.Combined with the development of the digital economy,the article discusses the mechanisms through which urban agglomerations promote digital transformation from both demand and supply perspectives.Using panel data of Chinese prefecture-level and above cities from 2011 to 2021,this article is based on the implementation of China's urban agglomeration strategic planning and constructs a double difference model of policy identification to test the impact of urban agglomerations.The results indicate that the implementation of urban agglomeration policies significantly promotes the development of the digital economy.Furthermore,the article conducts an empirical analysis of the mechanism of urban agglomerations in promoting the development of the digital economy from three aspects:the expansion effect of digital demand,the spillover effect of digital technology,and the supporting effect of factors such as talent and capital.In addition,the heterogeneous analysis finds that both central cities and non-central cities can enjoy the digital dividends brought by urban agglomerations.In comparison,the effect of urban agglomeration development in the eastern region is more obvious.Based on the findings of this study,it is necessary to strengthen the coupling coordination between regions and industries,optimize the spatial layout of economic activities and promote digital transformation.At the same time,this article also provides certain theoretical explanations and factual support for promoting the development of new quality productive forces through regional integration.
