Based On The Improved Correlation Method,The Research On The Correlation Change Of Industrial Structure In The Interval Of Four Provinces In Northwest China

In the trend of social and economic globalization and integration,striving for harmony is the pattern of regional coordinated development,and the rapid economic development cannot be separated from the optimization and upgrading of industrial structure and industrial transfer.Economic growth is realized in the continuous release of energy in the coordinated development of regions and the continuous optimization and upgrading of industrial structure,so the change of industrial structure and the coordinated development of regions are the eternal theme of economic growth.In 2013,China put forward the initiative of jointly building the silk road economic belt in the west.It is of great significance to study the evolution of industrial structure in westernBased on carding domestic and foreign industrial structure evolution theory and literature,based on the use of 2007,2012,four northwestern provinces(gansu,ningxia,qinghai,xinjiang)of input-output table,at the same time learn from Chinese scholars,the grey system theory proposed by Deng julong,analyzes on the application of the model representing the correlation condition,solve the starting point for sequence data and reference sequence change brings the results not only and dimensionless processing can destroy data inherent relations;In addition,the input-output analysis method is used to construct the reference sequence of the virtual optimal forward-backward effect and comprehensively analyze the optimization idea of its correlation effect with all departments,so as to objectively and truly reflect the driving role of the industrial sector and the evolution of the leading industry.Then,from the perspective of regional coordinated development,the paper divides the country into six regions based on the input-output table of 2012,calculates the transfer amount of land resources between regions,obtains the industrial transfer amount between regions,and analyzes the evolution and transfer rule of industrial structure between regions.Based on the empirical study of this paper,conclusions are drawn :(1)the leading industries in gansu province are mainly metal products industry,metal mining industry,and instrumentation industry;In the leading industries of qinghai,the manufacturing of metal machinery takes an increasing proportion and is resource-intensive.Among the leading industries in xinjiang,the secondary industry is mainly composed of metal products,machinery and equipment repair services,instruments and meters,and waste products.Agriculture also ranks high;Ningxia is mainly engaged in metal products,machinery and equipment repair services,and oil and natural gas exploitation products.(2)based on the perspective of regional correlation,the paper constructs a framework for the transfer amount of ecological resources in the province,and calculates the land resources occupied by the inter-province industries in China.The results show that the industrial economic relation between northwest China and other regions is gradually strengthened in recent years.And the industrial sector of the western region is occupied by other provinces more,the transfer is positive.Few industries have the resources of other regions to develop their own economies.(3)the specific performance is:(1)agriculture,forestry,animal husbandry and fishery belong to the "weak area supply strong area," the agriculture in the northwest region is to other provinces transfer,(2)industry belongs to the occupation industry,the industrial base is strong area,the development speed is faster,or even transfer the foundation of the poor area of other resources.The construction industry in the context of consumption,investment,province region difference is big,the southwest,the central and southern region transfer volume shows an obvious growth trend transportation and storage industry,wholesale and retail,the west,the northeast region transfer volume is large,this with east China,central and southern China.The geographical conditions of north China are better,the geographical location is superior,the population is dense,the economy is developed and other factors are closely related.Other service industries in the investment,consumption,exports,mostly occupied industries.The analysis shows that the more developed the middle and eastern regions occupy the more resources in the western and northeastern regions,especially in some provinces with the advantage of resource endowment,the more industrial resources are transferred,so how to narrow the regional economic gap and promote the coordinated development between regions is still the main problem.
