Outline
With high-quality development of economy, green innovation has emerged as a crucial driving force for fostering sustainable and healthy economic growth. Digital industry agglomeration can promote the agglomeration of factor resources and industrial transformation and upgrading, thereby enhancing regional green innovation efficiency. Based on the panel data of 30 provinces(due to the lack of data, the statistical data mentioned here do not include the Tibet Autonomous Region, the Hong Kong Special Administrative Region, the Macao Special Administrative Region and Taiwan Province)from 2012 to 2021, the Super-SBM model and location entropy were used to measure the evaluation indicators of green innovation efficiency and digital industry agglomeration, subsequently, the effects and mechanism of digital industry agglomeration on green innovation efficiency were examined. The results indicate that digital industry agglomeration contributes to the enhancement of regional green innovation efficiency. Due to the differences in geographical location and technology input level, the enhancement effect of digital industry agglomeration on regional green innovation efficiency is more significant in the eastern region and high-tech input provinces. Mechanism analysis shows that digital industry agglomeration can improve regional green innovation efficiency by promoting the upgrading of industrial structure. In view of this, each province should actively promote the development of digital industry clusters, scientifically formulate differentiated digital industry development strategies and promote the upgrading of industrial structure, so as to help the steady improvement of regional green innovation efficiency.
