Research On Coordinated Development And Influencing Factors Of Logistics Infrastructure And Regional Economy In Beijing-Tianjin-Hebei

In 2014,with the proposal of the Beijing-Tianjin-Hebei coordinated development strategy,the regional economy and logistics industry in the Beijing-Tianjin-Hebei region continued to develop rapidly,and the importance of logistics infrastructure could not be ignored in the process of development,which led to the rapid planning and construction of logistics infrastructure.As an essential and most important factor in the development of regional economy,logistics infrastructure plays a vital role in the development of regional economy.Based on the data of 13 prefecture-level cities in Beijing,Tianjin and Hebei,and according to the principle of index system construction,this paper reasonably constructs the comprehensive evaluation index system of the two,and measures the comprehensive level of the two by using the entropy weight method.On this basis,the coupling coordination degree of logistics infrastructure and regional economy in Beijing,Tianjin and Hebei prefecture-level cities is measured by the coupling coordination degree model.The Moran’s I index is used to test the global and local autocorrelation of the coupling coordination between Beijing,Tianjin and Hebei in 2011-2020.Finally,using the spatial lag model and the spatial error model,the paper analyzes the influencing factors of the coupling coordination between the logistics infrastructure and the regional economy in Beijing-Tianjin-Hebei region.The results show that the comprehensive development level of logistics infrastructure and regional economy in Beijing,Tianjin and Hebei are constantly improving.The degree of coupling and coordination also shows an upward trend,but there is still a relatively large gap between the coordinated development levels of the prefecture-level cities.As of 2020,among the prefecture-level cities in Beijing,Tianjin and Hebei,6 cities are in the stage of good coordinated development and high-quality coordinated development,3 cities are in the stage of intermediate coordinated development and primary coordinated development,and 4 cities are in the stage of unbalanced development.The spatial distribution pattern of coupling coordination degree shows a centralized distribution and local jumping trend,which is high in the central region and low in other regions as a whole.Through spatial econometric analysis,it is concluded that the overall Moran’s I index is all positive,indicating that the coupling coordination degree of the logistics infrastructure and regional economy in Beijing-Tianjin-Hebei has spatial autocorrelation and is positive.At the same time,most of the prefecture-level cities in Beijing-Tianjin-Hebei are located in the first and third quadrants in the Moran’s I scatter diagram,indicating that the coupling coordination degree of the prefecture-level cities in Beijing-Tianjin-Hebei has spatial agglomeration characteristics,namely,high-high aggregation and low-low aggregation.Among the influencing factors of the coupling coordination degree of Beijing,Tianjin and Hebei,all the influencing factors are positive,and the order of the degree of influence is the level of urbanization,industrial structure,per capita GDP,the level of logistics development,innovation capacity and the number of labor.In order to better meet the development needs of regional economy and improve the coordinated development of logistics infrastructure and regional economy in Beijing,Tianjin and Hebei.According to the analysis results and the actual development of regional economy and logistics infrastructure in Beijing-Tianjin-Hebei,some suggestions are put forward to improve the coordination level of logistics infrastructure and regional economy in Beijing-Tianjin-Hebei from two aspects: the whole region and prefecture-level cities.
