The Impact of Digital Economy Development on Green Innovation Efficiency:From the Perspective of High-Quality Population Development
Based on the perspective that high-quality population development supports Chinese-style moderniza-tion,this paper uses panel data from 30 provinces(autonomous regions and municipalities)across China between 2013 and 2021.It selects a two-way fixed-effects panel model,a panel threshold model,and mechanism analysis for empirical testing,aiming to investigate the impact and mechanism of digital economy development on green innovation efficiency.The research demonstrates that digital economy development significantly contributes to promoting green in-novation efficiency,with noticeable regional disparities.Moreover,high-quality population development serves as a crucial pathway for enabling green innovation efficiency through the digital economy.Regarding the influence of digital economy development on green innovation efficiency,both key variables-namely,digital economy and high-quality population development level exhibit significant threshold effects.After surpassing the single and double thresholds,respectively,digital economy development substantially enhances green innovation efficiency.Therefore,it is impera-tive to focus on the development of digital economy,delve into avenues to enabling high-quality population develop-ment through the digital economy,and bridge regional gaps in digital economic development to effectively enhance green innovation efficiency.
