Analysis Of My Country's Industrial Association Network

In recent years,China's economy is facing downward pressure.In view of this situation,China has proposed supply-side structural reform to adjust the economic structure,realize the precise allocation of economic factors,promote the effectiveness of supply,and enable China's economy to achieve sustainable and healthy development.An important part of the supply-side structural reform is to adjust the industrial relationship,so that the optimal combination between industries can be achieved and the industrial relationship can reach the optimal state.The law of world economic development and academic research show that countries or regions with a high degree of industrial correlation have better economic development.It is an effective measure to optimize the industrial structure,improve the efficiency of industrial resource allocation and promote the high-quality development of industrial economy to improve the degree of industrial correlation.Therefore,it is of great significance to analyze the industrial correlation in China.On the basis of combing relevant domestic and foreign research literature,this paper USES weaver Thomas index to calculate the threshold value of the input-output data of 42 departments in China in 2012 and 2017,and processes the input-output matrix into an adjacency matrix for complex network analysis based on the calculated threshold data,so as to establish an industrial correlation network.Later,for the construction of industrial connection network were analyzed,and the analysis of content containing industry association network node as a whole,industry,industry subgroup and structural holes in four aspects,the analysis method with network connectivity analysis,small world,network density,network reciprocity analysis,node degree analysis,node centricity analysis,clustering coefficient,condensing subgroup analysis,model analysis and structural holes of complex network analysis method.Among them,the network connectivity,small world,the density of network analysis and network analysis of reciprocity is mainly analyzed are the overall characteristics of our country industry association network,the node degree analysis,node centricity analysis and clustering coefficient of correlation analysis is the analysis of the main industry network nodes,the inheritance of condensing subgroup and the block model used to analysis industry association network industry subgroup,and the hole structure analysis is used to analyze the industrial connection network structure of the hole.Based on the above analysis,the conclusions are drawn as follows: first,the overall connectivity of China's industry-related network is small worldwide,but its tightness and stability are poor;Secondly,there are some extremely important industries in China's industrial network.Chemical products,finance,wholesale and retail,transportation,warehousing and postal services,and leasing and commercial services.These five industries are connected to each other and are in a central position.Thirdly,the aggregation of industrial subgroups in China's industry-related network is obvious,but the development of the industry-related network is unbalanced and the subgroups are not closely related.Fourth,highly competitive and development in our country industry association network advantages but also easy to become the restriction factor of industry are: chemical products,metal smelting and rolling processing,wholesale and retail,finance and leasing and business services,the five occupy our country industry association network structure of hole position,can carry on the resources to other industries in industrial network control;Fifth,the development trend of China's industrial network is good.Based on the above conclusions,this paper puts forward some Suggestions for the optimization of industrial relationship in China.First,the introduction of preferential policies to encourage the flow of resources and information between industries makes the relationship between industries closer.Second,give priority to the development of key industries and promote the common development of other industries.Thirdly,we should pay attention to the integrated development of marginal industries to make the whole industry more stable and improve the anti-risk capability of the whole industry.Fourth,we should increase support for the development of China's tertiary industry and promote the development of other industries through the service sector so as to rationalize the industrial structure.
