Research On The Dynamic Coupling Of Logistics And Information Industy In The Yangtze River Economic Belt

The Yangtze River economic belt,which spans the east,the middle and the west of China,is a huge engine to drive China’s economic development and inject fresh energy into the economic development.The construction of the Yangtze River economic belt has officially become a national development strategy.Promoting the coordinated development of the logistics industry and information industry in the Yangtze River economic belt is one of the important tasks of the economic development and industrial layout of the Yangtze River economic belt,and also one of the major development strategies of China.At the time of achieving the first centenary goal,we should seize the opportunity of information industry development,get rid of the shackles and constraints of traditional extensive logistics growth mode on the sustainable development of the logistics industry in the Yangtze River economic belt,promote the transformation and upgrading of the logistics industry,promote the deep integration of the logistics industry and the information industry,closely follow the indicators and requirements of the logistics industry and the information industry,and explore the development of the logistics industry and the information industry in the new era New mission and new requirements.We need to make up for shortcomings and increase capacity in an all-round way,help the high-quality development of the Yangtze River Economic Belt on the premise of stable growth of the logistics industry and information industry,and provide new impetusand new ideas for regional coordinated development.This paper takes the logistics industry and information industry of the Yangtze River economic belt as the research object,using the interdisciplinary perspectives of economics and geography to study,in order to calculate the comprehensive development level and the coupling and coordinated development level of the logistics industry and information industry of the Yangtze River economic belt.Firstly,this paper analyzes the current situation and existing problems of logistics and information industry in the Yangtze River economic belt.Secondly,construct the evaluation index system of logistics and information subsystem,and use entropy model to evaluate the comprehensive evaluation value of the logistics and information subsystem of the Yangtze River economic belt from 2003 to 2018.Thirdly,the coupling coordination degree model is used to measure the coupling coordination level of the composite system of logistics industry and information industry.Finally,the spatial autocorrelation model is used to analyze the overall spatial autocorrelation and local spatial autocorrelation of the coupling coordination degree of the Yangtze River economic belt,so as to explore the spatial correlation of the coupling coordination of logistics industry and information industry in the Yangtze River economic belt.The results show that:(1)on the whole,the logistics industry and information industry in the Yangtze River Economic Belt continue to develop,but the development of the remaining areas is not balanced;(2)in terms of time sequence,the comprehensive development level of the logistics industry subsystem and information industry subsystem in the Yangtze River Economic Belt continues to rise,the coupling correlation degree is relatively stable,and the coupling coordination degree continues to improve,which has evolved from the extremely maladjusted recessiontype to the primary level Coordinated development;(3)spatially,among the three representative research time points in 2003,2010 and 2018,the comprehensive development level of 11 provinces and cities in the Yangtze River economic belt is uneven,showing a pattern of decreasing from the lower reaches of the Yangtze River economic belt to the upper reaches,as is the coupling coordination level;(4)in terms of industrial development type,the number of logistics leading provinces and cities is far higher than that of information leading provinces The number of cities,and the information leading provinces and cities are mainly concentrated in the lower reaches of the information industry development level;(5)in terms of spatial correlation,there is a spatial positive correlation between the coupling coordination degree of logistics industry and information industry in the Yangtze River economic belt,that is,the provinces and cities with high coupling coordination degree are surrounded by the provinces and cities with high coupling coordination degree,and the provinces and cities with low coupling coordination degree are surrounded by the provinces and cities with low coupling coordination degree The H-H type of the coupling and co scheduling is mainly distributed in Shanghai,Zhejiang and Jiangsu in the lower reaches of the Yangtze River economic belt.In order to realize the deep integration of logistics industry and information industry in the Yangtze River economic belt,this paper puts forward suggestions on the coordinated development of logistics industry and information industry in the Yangtze River economic belt from three aspects: strengthening the infrastructure construction of logistics industry and information industry,establishing the concept of regional overall development and giving full play to the guiding role of the government,which has practical guiding significance.
