The digital economy plays an important role in promoting regional green innovation. Based on the panel data of 30 provincial administrative regions in mainland China (except Tibet) from 2011 to 2018, this paper constructs a comprehensive development index of the digital economy and explores the potential path of the digital economy affecting regional green innovation through factor analysis and regression analysis. The results show the following: Firstly, the digital economy can effectively promote regional green innovation capability. The causal relationship is mainly realized through scientific research funds and human resources. Secondly, in terms of regional heterogeneity, the role of the digital economy in promoting green innovation and R&D investment in eastern China is stronger than that in central and western China. Thirdly, further analysis showed that the digital economy has a significant nonlinear influence on regional green innovation capability. This feature is mainly reflected in the influence of R&D personnel on regional green innovation. Therefore, the rational allocation of R&D resources is conducive to the development of regional green innovation. Finally, it is suggested to improve the two mechanisms of R&D funds and personnel investment to actuate regional green innovation development.

In this paper, we use panel data of 13 cities in the Beijing-Tianjin-Hebei region from 2012 to 2020 to analyses the economic level development adopting the entropy method, and then by a Tobit panel regression model to analyze the impact of education on the development of economic quality. It turns out that: (1) Relationship between education level and economic quality development in the Beijing-Tianjin-Hebei area is an inverted "U" shaped; (2) the overall distribution present a trend of rapid development of education and faster economic quality development in the Beijing-Tianjin region and slower development in the Hebei district; (3) finally, on the basis of the measured relationship between education and economic quality development , from the outcome of the modulation variables, the horizontal of transportation, the level of Internet advancement, the level of manufacturing employment on the level of economic mass development in the Beijing-Tianjin-Hebei region play a role in promoting. In view of the above, practical suggestions put forward to optimize the allocation of educational resources in the Beijing-Tianjin-Hebei region and to boost harmonized high-quality economic development.
