The Research On Industrial Relevance In Yunnan Province Based On Social Network Analysis

The rapid economic development of China during the past 40 years of reform and opening up has also been accompanied by many contradictions.At present,China’s economy is still in a state of low level and inefficiency,the allocation of resources is irrational,and the configuration of industries is not balanced.The objective of the structural reform on the supply side is to adjust the economic structure so that the elements can be optimally configured and the quality and quantity of economic growth can be improved.An important aspect of the structural reform on the supply side is to achieve an optimal combination of industries and make the industry associated with an optimal state.The development experience of countries in the world shows that the synergies between industries have an important role in promoting the rational development of the economic structure.Strengthening the degree of industrial linkage is the basis for structural adjustment and transfer,and it is also an important measure to promote industrial transformation and upgrading.Only by increasing the level of industrial linkage can we promote the optimization and upgrading of the industrial structure so that we can achieve reasonable development under the new normal.This requires not only cultivating new points of economic growth,but also increasing the strength of the relationship between industries and optimizing the balance of economic structure.Therefore,the issue of industrial linkages urgently needs to be resolved.Under the background of “One Belt and One Road,” Yunnan Province faces Southeast Asia,South Asia,and West Asia.It also communicates with the Pacific Ocean,the Atlantic Ocean,and the Indian Ocean.Yunnan moves from marginal areas and “periphery” to open frontiers and radiation centers;Yunnan has to implement “introduction” and For the "going out" strategy of opening up,then we must have the functions of industrial agglomeration and industrial diffusion.Therefore,the adjustment of Yunnan’s industrial structure,the strengthening of industrial ties,and the highlighting of industrial rationalization and heightening have an urgent background of the times and the requirements of the times.This paper uses social network analysis(SNA)as a tool for researching industry associations,and analyzes the interrelationships among various industries in Yunnan through the data of input-output tables,thus excavating important correlation rules in Yunnan’s industrial system.First,based on the complete consumption coefficient matrix,the SNA model is mainly established through backward demand.Secondly,by analyzing the industrial structure of Yunnan Province and establishing a network of Yunnan Province’s industries,we made a map of the industrial structure of Yunnan Province;using the “centrality” analysis in SNA theory—quantitative rights,condensed subgroups,correlation and cohesion,and structure The hole index quantifies the industrial structure of Yunnan Province.Through an empirical study of the strength of industrial linkages in Yunnan Province,we found some problems in Yunnan’s industrial structure,such as the lack of support for high-tech industries and the unity of the industrial structure,so as to propose solutions to rationalize the economic development.Suggest.
