长江经济带交通基础设施碳解锁策略研究OA

Transportation infrastructure,as the foundation and pilot industry of the national economy,and its carbon unlocking is one of the key issues concerning China's sustainable development,so it is necessary to explore the emission reduction law of regional transportation infrastructure in the process of economic development.The Yangtze River economic belt,which spans the east,middle,and west regions of China,is the center of China's economic development and an important carrier of regional high-quality development.Therefore,nine provinces and cities in the Yangtze River economic belt(Shanghai,Chongqing,Sichuan,Jiangsu,Zhejiang,Anhui,Jiangxi,Hubei and Hunan)are selected as study cases.Existing studies on carbon unlocking have mostly explored the influence relationship between single factors and outcomes,and the conclusions of the studies mainly rest on whether each factor promotes or inhibits the realization of carbon unlocking,while these influencing factors are often interdependent rather than independent.In this paper,data from nine provinces and cities in the Yangtze River economic belt from 2012 to 2021 are used as sample cases,and constructs an index system of influencing factors by combining the six major conditional elements of green technological innovation,R&D investment degree,government subsidy,scientific and technological support strength,pollution control strength,and environmental regulation from the three dimensions of technology,economy,and institution,and applies the method of fuzzy set qualitative comparative analysis(fsQCA)to explore the impact of multifactor on the carbon unlocking of transportation infrastructure.Using fsQCA to analyze the causality and mechanism of multiple influencing factors on the carbon release of transportation infrastructure,and to form a research report on the carbon release strategy of transportation infrastructure in the Yangtze River economic belt.The study found that(1)none of the factors can be regarded as a necessary condition leading to the result that the Yangtze River economic belt does not have a high carbon emission intensity,and the realization of the control of the carbon emission intensity of the Yangtze River economic belt requires the joint action of all the conditions.(2)Each antecedent condition produces four groupings of carbon emission intensity reduction through synergistic linkage,and the results of these four groupings reflect the multiple strategies and complex mechanisms for realizing the carbon unlocking of transportation infrastructure in the Yangtze River economic belt.These are system-guided strategy,economy-driven strategy,system-economy dual synergy strategy,and economy-technology dual synergy strategy.(3)Green technology innovation plays a prominent role in controlling the carbon emission intensity of the Yangtze River Economic Belt,indicating that the promotion of the technological level is crucial to the carbon unlocking of transportation infrastructure in the Yangtze River economic belt.The research results reveal the complex interaction of multiple factors in the emission reduction and carbon reduction of transportation infrastructure in the Yangtze River economic belt and provide theoretical support for grouping carbon-unlocking strategies for transportation infrastructure in the Yangtze River economic belt.Finally,based on the analysis of the grouping strategy,specific countermeasures and suggestions are proposed to promote the carbon unlocking of the transportation infrastructure in the Yangtze River economic zone,thus helping to realize the dual-carbon goal.
