IMPACT OF LOGISTICS INDUSTRY AGGLOMERATION ON THE SUSTAINABLE DEVELOPMENT OF CITIES IN THE FRAGILE ECONOMIC ZONE OF WESTERN CHINA

Deepening the construction of the logistics industry in the economic zone of the fragile ecological environment in western China is of great significance to the sustainable development of the city. In this paper, taking the Xinjiang region in western China as an example, the urban logistics node division system, urban logistics integration strategy, and the static and dynamic evaluation of logistics industry efficiency are systematically studied. The results of the study show that the Xinjiang region has now formed a logistics system with railways as the mainstay and highways and aviation as the supplement. In the actual operation, the pattern of railway logistics still exists and will exist for a long time. The integration of logistics nodes in western cities in China is an inevitable requirement for sustainable urban development. Among them, the integration of transportation and communications infrastructure is the prerequisite, and the integration of energy cooperation is the focus. Invalid scale is the main reason that affects the inefficiency of the logistics industry in western China. The logistics industry is generally in a state of diminishing returns to scale, which shows that the logistics industry in western China has reduced its resource allocation capacity and high logistics costs due to the excessive market size. The pure technical efficiency of the eastern region is always in an efficient state, and the ineffectiveness of scale is the main reason for the ineffectiveness of the static efficiency of the logistics industry. The logistics industry in the eastern region is superior to the central and western regions in terms of institutional level, management capability and technical level, and compared to other regions, the eastern region is closer to the optimal production scale. Dynamic efficiency and technological progress in the eastern region change in the same direction, and technical efficiency and scale efficiency change in the same direction, indicating that technological progress and scale factors have a greater impact on the productivity changes of the eastern logistics industry. This research has important reference value for accelerating the development of logistics in the economic zone of fragile ecological environment.
