Driving Mechanism of Synergistic Efficiency in Reducing Pollution and Carbon: Evidence From 249 Green Parks

ABSTRACT The green park serves as a significant spatial carrier for China's strategy to become a manufacturing powerhouse and promote industrial transformation and upgrading. It is a crucial platform for implementing and driving the transformation and development of green manufacturing, promoting green development and harmonious coexistence between man and nature in the current era. The main focus of this study is a total of 249 green parks announced by the Ministry of Industry and Information Technology, and it employs the multi‐time point PSM‐DID method to investigate 280 prefecture‐level cities. The results show that: (1) The coefficient of the green park certification policy is estimated to have a significantly negative impact at the 1% significance level. (2) The green park certification facilitates the integration of pollution reduction and carbon reduction efforts by leveraging green technology innovation and government support. (3) The promoting effect of green industrial park certification has regional consistency and resource heterogeneity. Therefore, it is of great significance to study the effects and pathways of green park certification on the synergies of carbon and pollution reduction.
