Study on the Impact of Digital Economy on High-Quality Development in Sichuan Province

Abstract

This paper constructs a multidimensional indicator system based on the panel data of 18 prefecture-level cities in Sichuan Province from 2005 to 2021 to empirically analyse the impact of digital economy on the high-quality development of regional economy. It is found that the digital economy significantly enhances the level of high-quality development in Sichuan Province by promoting technological innovation, optimising resource allocation and promoting industrial upgrading; its impact is heterogeneous in both spatial and temporal dimensions. Chengdu City, as the core area of arithmetic, has the most significant driving effect; while the marginal effect of digital economy in high output value regions is much higher than that in low output value regions, reflecting the important moderating role of technology absorption capacity. Based on this, this paper puts forward policy suggestions such as optimising the layout of digital infrastructure, deepening the reform of the data factor market, and cultivating the new industry of "digital + culture and tourism" to provide theoretical support for narrowing the regional development gap and promoting the transformation and upgrading of the western economy.
