Research on the Spatial Characteristics and Impact Mechanism of Carbon Emission Efficiency of Chinese Road Freight Transport Enterprises

Le résumé fourni par la source

The highway transportation industry is an important component of the transportation industry and one of the key industries causing global climate change. Studying the carbon emission efficiency and influencing factors of enterprises in this industry is of great significance. To identify the carbon emission level of highway transportation enterprises, this article uses a set of table data from China's highway and waterway transportation enterprises to calculate the emissions of carbon sources from the movement of trucks in highway freight transportation enterprises using the "top-down" method. Based on this, the RAM model is used to calculate the economic efficiency, carbon emission efficiency, and unified efficiency of road freight transportation enterprises, and the characteristics of the three types of efficiency are analyzed to further explore the factors that affect the carbon emission efficiency of enterprises. The research results indicate that: (1) both economic efficiency and carbon emission efficiency exhibit spatial agglomeration characteristics, but in 2021, the degree of spatial agglomeration has decreased. (2) From 2020 to 2021, the carbon emission efficiency rankings of various regions remained relatively stable, with the western region, eastern region, central region, and northeastern region ranking in order of carbon emission efficiency; Due to the impact of the epidemic, the economic efficiency of various regions has fluctuated to some extent in 2020-2021, and the fluctuation of unified efficiency is closer to the fluctuation of economic efficiency. (3) The analysis results of the impact on carbon emission efficiency are as follows: the faster the Internet develops, the more stringent the urban environmental requirements are, the higher the carbon emission efficiency of road transport enterprises will be; The more diversified the business model and the longer the transportation distance, the higher the carbon emission efficiency of the enterprise.
