| As an important engine of national economy,logistics industry brings a series of problems to regional environment and energy while promoting economic growth.The green total factor productivity of logistics industry is the core issue of regional logistics industry development,which can reflect the high quality development level of logistics industry.With the popularization of informatization and digitalization,the proportion of digital economy in the national economy is gradually increasing.The effective application of data and information technology can improve the efficiency of resources,optimize the industrial structure,and thus promote the cleanliness of production.The state has vigorously developed digital logistics by issuing relevant documents such as "Opinions on the Implementation of " Internet + " Efficient Logistics",so it is necessary to study the coordination degree between digital economy and logistics green total factor productivity.This paper studies the coupling and coordination relationship between digital economy and green total factor productivity of logistics industry to provide reference for the coupling and coordination research between other industries and digital economy.On the basis of introducing the concepts and theories of digital economy and green total factor productivity of logistics industry,the level of digital economy and green total factor productivity of logistics industry are studied.Combined with the development environment of digital economy,the development level index of digital economy is constructed to evaluate the level of regional digital economy.Analyze the development environment of logistics industry,and calculate and evaluate the green total factor productivity of logistics industry by considering the non-expected output of logistics industry such as carbon dioxide.On the basis of calculating the level of digital economy and green total factor productivity of logistics industry,the coupling coordination degree of 30 provinces and cities in China was analyzed by using the coupling coordination model.Finally,the geographic detector model is used to detect the factors affecting the coupling coordination degree,find out the factor with the strongest explanatory power,and put forward corresponding suggestions according to the detection results.Conclusions:(1)from 2013 to 2019,the GTFP of digital economy and logistics industry showed an overall upward trend.There are regional differences in the level of digital economy,showing a decreasing distribution pattern from the eastern coastal areas to the northwest inland.The GTFP of logistics industry was always at a high level in Sichuan Province,and at a low level in Shaanxi-Gansu-Ningxia region.The GTFP of logistics industry in Xinjiang increased most obviously.(2)During the study period,from the perspective of time series,the coupling coordination degree between digital economy and green total factor productivity of logistics industry was on the rise,and the coupling coordination degree gradually changed from mild imbalance to barely coordination,and the scope of coupling coordination was gradually expanded.In terms of regions,the coupling degree of the eastern region is relatively high,followed by the central region,and the western region and the northeast region are relatively low.From the perspective of spatial correlation,the coupling coordination degree in most years has a positive spatial correlation,and Guangdong,Zhejiang and Jiangsu provinces show high aggregation.(3)In factor detection,logistics technology innovation has the strongest explanatory power for coupling coordination degree;In the detection of interaction factors,Q value of interaction between logistics technology innovation and urbanization is the highest,indicating that technological innovation and urbanization development are key factors for coordinated development of digital economy and green and high-quality logistics.Figure [24] Table [16] Reference [88]... |
