Extractive Industry Concentration Degree Of Cluster Analysis Of The Equilibrium Level Of Measurement

Industrial clusters appear due to its continuous innovation and competitive advantage, become a major force in industrial growth, economic development in many countries an important feature. Extractive industry is the basic industry of national economy, the development of extractive industries in various sectors to provide a wealth of raw materials, play a supporting role in national economic development, Chinese extractive industry is currently still in the initial stage of industrial clusters, single industrial structure, the form of supply chain lack of diversity and vitality of the relationship between members of the cluster is mainly reflected in the relationship between the supply of natural resources, cluster relatively closed and so on. Industry concentration degree of the cluster there is a balanced level, this time to reach Pareto optimal allocation of resources, the paper as a starting point, the use of industry concentration, by selecting the degree of long-run equilibrium cluster concentration level indicators, the establishment of industrial clusters reflect the concentration degree of equilibrium level regression model to analyze the impact of each variable, and so the development of industrial clusters measures.The main conclusions are as follows:⑴the relationship between cluster size and effect. Based on the limited nature ,derived cluster size and cluster effect relationship between the existence of an equilibrium level of industrial clusters, the largest cluster effect at this time.⑵cluster measure of the equilibrium level of concentration degree. Analysis of long-term concentration levels of industrial cluster of factors - economies of scale, market demand, industry growth, etc., by selecting indicators of different factors on the various indicators to quantify, the establishment of the equilibrium level of industrial concentration degree of the cluster model, using the Eviews, the regression results and variable analysis, the resulting cluster mining industry concentration degree of the long-run equilibrium level.⑶Extractive industry cluster development measures. Focus on supporting the central and western regions; accelerate the industry growth rate; improve the government's policy; play role in promoting the guild.
