Analysis And Research On Industrial Linkage In Guizhou Provinc

In recent years,Guizhou has made historic achievements in economic and social development.The economic growth rate of Guizhou has ranked among the top three in China for ten consecutive years,and the regional GDP has been rising steadily.However,there are still many problems,such as unbalanced industrial development.At present,the industrial development of Guizhou is in the era of great strides,In order to make Guizhou’s economy and society better,faster and healthier,it is necessary to constantly optimize the industrial structure,optimize the combination of industries,and improve the degree of industrial correlation.Therefore,it is necessary to analyze the network structure and influencing factors of industrial association network in Guizhou.In this paper,the input-output data of 42 departments in Guizhou province in 2002,2007,2012 and 2017 were calculated by using the direct consumption factor of the input-output method,and a 0-1 matrix was obtained.This paper analyzes the industrial linkage network from three aspects: network as a whole,network individuals and network subgroups.Among them,network integration analysis includes network connectivity,small world and network densities.The individual part of the network mainly analyzes the Degree Centrality,Betweeness Centrality,Closeness Centrality of industrial nodes.In the part of network subgroup,we mainly consider the analysis of condensed subgroup and block model.Finally,the Exponential Random Graph Model(ERGM)was used to construct multiple models from three aspects: endogenous structure effect,actor-relationship effect and covariate network effect to explore and analyze the influencing factors of the formation of industrial association network.Through the above analysis,the main conclusions of this paper are as follows:(1)The industrial association network of Guizhou is a small worldwide,and the connectivity is weak;(2)There are several extremely important industries in the industrial association network of Guizhou: finance,transportation,warehousing and postal service,leasing and business services,wholesale and retail,accommodation and catering,etc.These industries are in a core position and are related to many industries;(3)The sub-groups of the industrial association network in Guizhou are closely connected but unevenly developed;(4)The industry association network in Guizhou has self-organization and reciprocity,which has a significant impact on the industry association network;(5)Employment potential network and Common industry network have an important impact on the formation of industrial association network in Guizhou Province.Based on the above findings,this paper proposes the following recommendations:(1)encourage more resource integration and information circulation among industries,and strengthen the closeness of the relationship between industries;(2)Focus on the development of the service industry to promote the common development of other industries;(3)Improve the integrated development ability of isolated industries and marginal industries in the industrial association network,and make the association relationship of the entire industrial network closer and more stable;(4)Strengthen the expansion of industries and the correlation of each industry in the big industries(first,second and third industries)to improve the employment potential of each industry.
