环保督察制度对中国省域交通碳排放的影响效应研究OACHSSCD

As urbanization and infrastructure construction continue to accelerate,carbon emissions from transportation have become a key issue constraining global sustainable development.As a significant breakthrough in China's ecological and environmental govern-ance system,the environmental protection inspection system has achieved remarkable results since its implementation nine years ago.To explore the effect,evolution logic,and revelation of the environmental protection inspection system on transportation carbon emissions,the time lag effect and regional heterogeneity of the central environmental protection inspection system on China's transportation carbon emissions are analyzed by using fixed effect and multiple linear regression models with panel data from 30 provinces(municipalities and autonomous regions)in China from 2000 to 2022.The mediating-effect model is used to analyze the path and internal mechanism by which the environmental protection inspection system affects China's transportation carbon emissions.The results of the study show that:the environmental protection inspection can significantly inhibit transportation carbon emissions,and there is a time lag effect in the in-spection effect;the environmental protection inspection system has different starting times for the impact of carbon emission inspection in other regions,and the western region has certain characteristics of the campaign response;through the analysis of the role of the mecha-nism,the environmental protection inspection system reduces transportation carbon emissions by promoting technological progress,en-hancing the strength of environmental investment,and improving the structure of energy consumption.Building on this foundation,we propose targeted inspection plans,implementing region-specific priority oversight,and advancing technological innovation.These meas-ures aim to propel low-carbon transformation in provincial transportation systems across China,supporting green and low-carbon de-velopment and advancing the achievement of the dual carbon goals.
