Research On The Linkage Development Of Manufacturing Industry And Logistics Industry In Shaanxi Province From The Perspective Of Sub-industry Segmentation

At present,China's economic growth is slowing down,and it is facing the pressure of economic transformation.The adjustment and optimization of industrial structure is an important economic development strategy of the country.Manufacturing is a fairly large industry category.The goal of transformation and upgrading requires the logistics industry to provide professional services.In turn,the development of the logistics industry is inseparable from the demand of the manufacturing industry.It is of great significance to study the linkage development level of sub-sectors with different natures within the manufacturing industry and logistics industry to adjust the industrial structure of the manufacturing industry and to improve the development of the logistics industry.Then based on the theory of industrial relevance and the theory of synergy,qualitative analyzes the development relationship and characteristics of manufacturing and logistics industry and the internal motivation and development trend of the linkage development of the two industries.Secondly,it summarizes the development status of manufacturing and logistics industry from the aspects of overall scale and internal structure,and analyzes the input and output of the logistics industry and the different sub-sectors within manufacturing industry;The evaluation indicators are selected from four levels: industry scale,industrial performance,social contribution and development potential.The entropy weight method is used to determine the index weights,and the system comprehensive evaluation system and the coupling coordination degree model are constructed to explore the overall level of development of the two industries and between the two industries.Based on the degree of matching,the VAR model is constructed to study the impact mechanism of the manufacturing industry and the logistics industry.Finally,based on the empirical results,the corresponding development suggestions and opinions are given for the linkage development level and impact mechanism between the sub-sectors in each category of manufacturing and logistics industry.The paper finds that the capital-intensive industry has the strongest demand for the logistics industry,and the labor-intensive industry and the logistics industry have the highest level of coupling and coordination and the best development trend.The results of the VAR model show that Granger causality exists between the capital-intensive sub-sectors of the manufacturing industry and the comprehensive development level of the technology-intensive sub-sectors and the logistics industry.The latter is the Granger reason of the former.Improving the development level of the logistics industry will promote capital-intensive industries and technology-intensive industries.Therefore,it is necessary to vigorously develop the logistics industry,further improve the linkage mechanism between the logistics industry and the manufacturing industry,promote the development of technology-intensive industries,and promote the transformation and upgrading of manufacturing industries in Shaanxi Province.
