数字经济与黄河流域减污降碳协同治理的关系研究OA

To explore whether the digital economy can achieve coordinated governance of pollution reduction and carbon mitigation in the Yellow River Basin,an empirical analysis was conducted using panel data from 65 prefecture-level cities within the basin for the period 2003-2021.A fixed effects model was constructed for empirical analysis.Robustness tests were performed by altering the explained variable,employing instrumental variable methods and conducting quantile regression analyses.This study conducted a mechanism analysis on industri-al structure optimization,government regulation and green technology innovation.Additionally,the regional heterogeneity of the impact of the digital economy on the coordinated governance of pollution reduction and carbon mitigation was analyzed.The results indicate that:The digital economy significantly contributes to the coordinated governance of pollution reduction and carbon mitigation in the Yellow River Basin.Opti-mization of the industrial structure,government regulation and green technological innovation are key mechanisms through which the digital economy promotes the collaborative governance of pollution reduction and carbon mitigation.The influence of the digital economy on the coor-dinated governance of pollution reduction and carbon mitigation varies significantly in the upper,middle and lower reaches of the Yellow Riv-er Basin,and none of them have significantly promoted such collaborative governance in any of the three reaches.Therefore,it is imperative to establish a robust digital infrastructure to narrow the development gap in the digital economy among the upper,middle and lower reaches.Governments should play an active role in ensuring flexible and efficient regulation,promoting the free flow of elements such as data.By capi-talizing on the comparative advantages of factor endowments in each region,the digital economy can empower the synergistic governance of pollution reduction and carbon mitigation across the Yellow River Basin.
