On Spatial Disequilibrium and Influencing Factors of Logistics Efficiency in the New Western Land-Sea Corridor
The New Western Land-Sea Corridor had an important strategic position in the coordinated development of China's regions.It was of great practical significance to explore the temporal and spatial evolution and influencing factors of logistics efficiency to promote high-quality development of logistics industry in the New Western Land-Sea Corridor.In this paper,the Super-SBM model was used to measure the logistics efficiency of provinces along the New Western Land-Sea Corridor,and Dagum Gini coefficient method was employed to analyze the spatial disequilibrium characteristics and sources of logistics efficiency.Finally,the influencing factors of logistics efficiency were explored by means of geographic detector,revealing the difference in intensity of the same factor in different periods and its future trend.The results showed that:(1)the logistics efficiency of the provinces along the New Western Land-Sea Corridor from 2011 to 2020 showed a long-term positive trend.The logistics efficiency of the covered area and the hinge area was better than that of the extension belt.The logistics industry development of Hainan,Guangxi,Inner Mongolia and Ningxia was in good condition,while Qinghai and Tibet had consistently lagged behind,demonstrating a"Matthew effect"in the development path of logistics efficiency;(2)the logistics efficiency of the provinces along the Corridor had obvious spatial disequilibrium,exhibiting an overall fluctuating upward trend.The super-variable density was the main source of spatial disequilibrium,followed by intra-regional differences,and the contribution rate of inter-regional differences was the least;(3)urbanization level,agglomeration degree of logistics industry and regional economic development level were the core influencing factors of logistics efficiency,with their effect intensity gradually decreasing.Industrial structure and informatization level were secondary factors,and the scientific and technological innovation capability and the degree of opening up were general factors,with their effect intensity gradually increasing.
