高速铁路开通与碳排放耦合协调度时空演变特征及影响因素研究
Research on Spatial-Temporal Evolution Characteristics and Influencing Factors between Coupling Coordination Degree of Opening of High Speed Railway and Carbon Emission
摘要
Abstract
As an important symbol of modern green transportation,the opening of high speed railway not only drives the economic growth of the areas along the line but also helps improve the environmental quality to a certain extent.This paper constructed an index system for the opening of high speed railways and carbon emissions based on the entropy method and studied the spatio-temporal evolution characteristics and influencing factors of the coupling coordination degree between the opening of high speed railways and carbon emissions in 30 provinces of China from 2010 to 2022 by using the coupling coordination degree model and the spatial econometric model.The conclusions are as follows:From 2010 to 2022,the development level of high speed railway shows a significant upward trend,and the overall carbon emission level shows a downward trend.The coupling coordination degrees at the national level,regional level,and provincial level have all significantly increased.As of 2022,the number of provinces in the coordinated development stage has significantly increased.Economic development,urbanization,technological innovation,the improvement of financial development level,and the upgrading of industrial structure have a positive impact on the coupling coordination degree between the opening of high speed railways and carbon emissions.Environmental regulations and foreign direct investment have a negative impact on the coupling coordination degree between the opening of high speed railways and carbon emissions.关键词
