Study On The Coupling And Coordination Of Logistics Industry Development,economic Development And Ecological Environment For The Yangtze River Economic Belt

As one of the most economically influential and significant regions,the Yangtze River Economic Belt has seen rapid development of its logistics industry and economy.The rapid development of the logistics industry has strengthened industrial cooperation between the regions,accelerated the flow of resources in the process of economic development,and improved the efficiency of resource utilisation.A region with a high level of logistics development can attract more production investment and enterprises,increasing economic output and raising the level of economic development,while a fastgrowing economy generates a great demand for logistics,and the link between the two is increasingly strengthened.The development of the logistics industry and economic development both require energy consumption,and the emissions of waste gas and water,as well as the various types of packaging waste from the logistics industry’s transportation process,are harmful to the ecological environment,weakening the natural environment’s carrying capacity for production activities and reducing the development speed of the logistics industry and the economy.A superior ecological environment is conducive to the transformation and upgrading of the logistics industry,improving the level of development of the logistics industry and meeting the massive logistics needs of economic development more quickly.As a key ecological protection zone and core economic development area,it is necessary to reasonably evaluate the respective development levels of the logistics industry,the economy and the ecological environment(hereinafter referred to as the "three systems"),analyse the coupled and coordinated development of the three sub-systems,and formulate countermeasures in response to the results of the influencing factors to improve the results of the study show that as a result of the research work,it can be seen that.Based on the DEA model and the entropy-weighted TOPSIS method,the development level of the logistics industry,the economic development level and the ecological environment level of the Yangtze River Economic Belt were measured in turn,and then the coupled and coordinated development level of the logistics industry development,the economic development and the ecological environment were measured using the coupling coordination degree model to analyse their development differences and characteristics in time and space.Results: The development indexes of the three subsystems of logistics industry,economy and ecological environment continue to rise,with the development level of each system in the downstream being the highest and that of each system in the upstream being the lowest;the overall value of the coupling degree is higher than 0.920,and the "three systems" of each region and province are all at the stage of coordinated development;the downstream The Gini coefficient of the coupled and coordinated development level of the three systems in the upper reaches is the largest,which is the main source of the overall difference;from the shape of the kernel density curve,it can be seen that the coupled and coordinated development of the three systems in the Yangtze River Economic Zone as a whole The polarisation trend of the Yangtze River Economic Zone is gradually weakening.The spatial effects of the coupled and coordinated development of the logistics industry,economic development and ecological environment in the Yangtze River Economic Zone are examined to investigate the spatial clustering characteristics of the level of coordinated development among the systems.Using an exploratory spatial data analysis method,the spatial correlation of the coupled and coordinated development level of logistics industry development,economic development and ecological environment is examined from two perspectives: global and local.Results: From 2010 to 2020,the level of coupled and coordinated development of the three systems showed positive spatial correlation,with the number of provinces with high and high agglomeration characteristics increasing over time and the number of provinces with low and low agglomeration characteristics decreasing over time.To analyse the factors influencing the coupled and coordinated development of the logistics industry,economic development and ecological environment in the Yangtze River Economic Belt.Using a spatial econometric model,appropriate explanatory variables are selected to explore measures to promote the improvement of the level of coordinated development among the systems.The results: consumption demand,the level of scientific and technological input,human resources,the level of information technology,transport structure and green investment are the key factors affecting the coordinated development among the systems,among which the improvement of the transport structure element can improve the level of the "three systems".The level of coupled and coordinated development of the "three systems" can be improved to a greater extent by improving the transport structure.Finally,based on the analysis results,corresponding countermeasure suggestions are put forward.Figure 22 Table 16 Reference 83...
