环境规制、数字赋能对产业结构升级的影响及机理.

At present, prioritizing green development and promoting digital empowerment have become key paths in China's economic transformation. To explore whether 'green development' and 'digitalization' can achieve synergistic development at the industrial level, this paper used the panel data of 283 prefecture-level cities in China to innovatively verify the regulatory effect of the digital economy in the process of green transformation of the industrial structure. Firstly, the multiple threshold test was used to find the nonlinear relationship between environmental regulation and industrial structure adjustment. Based on the fitting of a high-order function, two adjustment variables--industrial digitalization and digital industrialization--were added to analyze the synergy between environmental regulation and digital empowerment. The results showed that: ① Environmental regulation had no significant impact on the rationalization of industrial structure but had a single threshold effect on the upgrading of industrial structure; that is, when the intensity of environmental regulation exceeded the threshold value, environmental improvement and industrial structure upgrading could achieve a winwin situation. ② The joint operation of industrial digitalization and environmental regulation led to a dual threshold effect in the rationalization of industrial structure. As the integration of the two deepened, synergistic development could be achieved by gradually reducing the intensity of environmental regulation. However, the joint operation of industrial digitalization and environmental regulation led to the disappearance of the single threshold effect of industrial structure upgrading, and the interaction coefficient was significantly positive but not stable. ③ The joint operation of digital industrialization and environmental regulation did not have a significant impact on the rationalization of industrial structure but had a single threshold effect on the advancement of industrial structure. As the integration of the two deepened, the intensity range of ecological and industrial synergistic development would gradually expand. From the heterogeneity regression results of local regions, the main conclusion could still be verified, but it was found that there was a phenomenon of pollution transfer from economically developed areas to underdeveloped areas. Based on the above conclusions, this study proposes that shortsighted behaviors of local environmental governance and the objective differences in the industrial levels of each region should be considered in the top-level design process. We should also guide the governments in the developed areas to pay more attention to the long-term driving force of green technology innovation and promote the deep integration of 'green consensus' and development goals.
