| The adjustment of industrial structure is nonferrous metal industry " Twelfth Five " planning work, postpartum link gradually extending reasonable layout is the top priority to promote the coordinated development of various sectors. In recent years, domestic non-ferrous metal industry appeared deficit aggravate, stock proportion rising gradually, industry profit fell sharply, ascending price blocked phenomenon, which seriously restricts the nonferrous metals industry in the "12th Five-Year Plan" power forward. As a result of nonferrous metal industry and its related industry exists between the mutual influence and restrict each other, so the non-ferrous metals industry and related industries will cycle through the influence between resulted in nonferrous metal industrial structure optimization is blocked. Based on this phenomenon, based on the latest2007135sectors input-output table, by using MATLAB and EXCEL software, the application of input-output analysis method in the analysis of nonferrous metal industry to its associated industry influence, clear non-ferrous metals industry and related industries in mutual influence the largest department, for non-ferrous metals industry and its related industries structure adjustment and put forward the corresponding policy suggestions.This article from the quantitative index calculation and price model to simulate two convenient sum of nonferrous metals industry in our country and association between industry influence. First of all, this paper calculates the nonferrous metal industry of influence coefficient, sensitivity coefficient, intermediate demand rate and investment rate and non-ferrous metals industry and related industry direct correlation coefficient and complete correlation coefficient, through quantitative analysis to determine the nonferrous metals industry and its related industries between the effect and correlation; secondly, establish input output price model for nonferrous metal industry and its related industry price change simulation analysis, further research of nonferrous metal industry price changes to the related industry influence. The empirical results show that, nonferrous metal industry should focus on the development of three sub non-ferrous metal rolling processing industry, rectification of non ferrous metal ore mining; non-ferrous metal sub three industries for the manufacture of metal products directly and indirectly provides the most products; non-ferrous metals three sub industries from the demand driven, oil and nuclear fuel processing waste, oil and natural gas mining industry, mining and washing of coal, electric power and heat production and supply industry, transportation industry, the wholesale and retail industry development; non-ferrous metal ore mining industry of backward and associated industry directly influence scope and degree of influence are relatively small, and non-ferrous metal smelting industry and non-ferrous metals rolling processing industry on other industries to correlate the affecting range and degree of similarity. Finally, China’s non-ferrous metals industry and associated industries how reasonable the structural adjustment and the use of resources put forward several policy recommendations. |
