成渝城市群物流业集聚对物流业碳排放的时空异质性影响研究
Spatial-Temporal Heterogeneity Impact of Logistics Industry Agglomeration on Carbon Emissions from Logistics Industry in Chengdu-Chongqing Urban Agglomeration
摘要
Abstract
The rapid development of China's logistics industry has led to a significant increase in energy consumption in the logistics industry,imposing substantial pressure on energy conservation and emission reduction in China's logistics industry.With the advancement of the Chengdu-Chongqing Economic Circle,the logistics industry in the Chengdu-Chongqing urban agglomeration has experienced rapid growth and has progressively developed into an agglomeration.Based on an analysis of logistics industry agglomeration levels and carbon emissions from the logistics industry in the Chengdu-Chongqing urban agglomeration from 2011 to 2020,this paper used the Moran index and local Moran scatter plot to analyze the spatial autocorrelation of carbon emissions from the logistics industry in the Chengdu-Chongqing urban agglomeration.The paper also studied the spatial-temporal heterogeneity impact of logistics industry agglomeration on carbon emissions from the logistics industry in different cities within Chengdu-Chongqing urban agglomeration at different time by using the geographically and temporally weighted regression(GTWR)model.The results show that the carbon emissions from the logistics industry in the Chengdu-Chongqing urban agglomeration are spatially clustered and relatively stable;the distribution of the impact coefficients of logistics industry agglomeration on carbon emissions from the logistics industry in the Chengdu-Chongqing urban agglomeration is spatially and temporally heterogeneous,and the distribution of impact coefficients in 2020 shows the trend of"high in the north and south and low in the east and west".关键词
