摘　　要：数字经济是促进新时代经济高质量增长的重要引擎。基于2011—2019年30个省份的面板数据,分别利用熵值法和DEA-Malmquist指数法测算我国省级数字经济发展综合指数与全要素生产率,实证探讨数字经济对经济高质量发展的影响效应。研究发现:数字经济能显著促进经济高质量发展,该结论经过一系列稳健性检验后仍显著成立;机制分析表明,数字经济是通过提升区域创新水平、加快产业结构升级赋能于经济高质量发展;进一步分析表明,数字经济对相邻地区的经济高质量发展存在空间溢出效应,数字经济对经济高质量发展的促进效应因区域、生产率与人力资本的不同而存在异质性。因而应积极推进数字化基础设施建设,协调好各地区数字经济的均衡发展,实施数字化驱动发展战略,推进经济的高质量发展。Accelerating the construction of digital economy is an important engine to promote the high-quality economic development in the new era. Based on the panel data of 30 provinces from 2011 to 2019, the comprehensive index of China’s provincial digital economy development and total factor productivity are calculated by using entropy method and DEA Malmquist index method respectively, and the impact of digital economy on high-quality economic development is empirically analyzed. It is found that the digital economy can significantly promote the high-quality economic development, and this conclusion is still valid after a series of robustness tests. Mechanism analysis shows that digital economy enables the high-quality economic development, by improving the level of regional innovation and accelerating the upgrading of industrial structure. Further analysis shows that the digital economy has the spatial spillover effect on the high-quality economic development of adjacent areas;the promotion effect of digital economy on high-quality economic development is heterogeneous due to different regions, productivity and human capital. Therefore, it is proposed to promote the construction of digital infrastructure, coordinate the balanced development of digital economy in various regions, implement the digital driven development strategy, and promote the high-quality economic development.
