| Located in the southwest of China,Yunnan province is rich for mineral resources,especially about non-ferrous metal resources because of the condiction of metallogenic,and is known as the "non-ferrous metal kingdom".From the areas distribution aspect,Yunnan non-ferrous metal resources are mainly distributed in the middle and western of Yunnan.From the metal's kinds,zinc,tin,copper,germanium and rare metal resources have the important status as the advantage resources in Yunnan province,and play an important role on the development of economy.Presently,China's economic development has paced into the”new normal”,which puts forward new requirements for the development of the non-ferrous metal industry.It is both opportunity and challenge under the background of this policy for Yunnan non-ferrous metals industry.In recent years,Yunnan non-ferrous industry chain that includes the selecting,smelting and processing industy is influenced by some kinds of factors such as supply and demand,price fluctuation,which leads to the excess production capacity and insufficient development.Besides,the low price of non-ferrous products generates some phenomenons that bring some influences to the stability and development of the society,such as “be unemployment” in order to reduce the cost of production.To sum up,the reason may be related to the uncoordination of industry chain,and it express the out-of-balance between the input and output,some serious excess or scarce for some products.If it lasts more long time,those can produce adverse effects to economic development in Yunnan province.Therefore,according to the non-ferrous metal industry chain development goal,properly handling the relationship of interests distribution between each link in the chain,building the interest coordination mechanism is the key way to promote yunnan non-ferrous metals industry from resource advantage to economic advantage transformation.In view of this,this paper will choose industry chain as the perspective,and will use benefit coordination mechanism as the research content aiming at the whole stable and efficient development of non-ferrous metal industry chain.On the basis of that,building the mechanism of interest coordination about non-ferrous metal industry chain for realizing the implementation of healthy development for the non-ferrous metal industry in Yunnan province.According to the above,first this paper will reveal present situation and problems of profit distribution in the three links(selecting,smelting,processing)of Yunnan nonferrous metal industry chain development through the literatures and datas,and then emphasize the basic development of the non-ferrous metal industry,the problem and the future of development in those three aspects.In the present basic development field,the two indicators are used to reveal the basic development situation and the profit distribution of each link through main business cost margins and industrial added value.In the description of the current situation of the development of the three links of the industrial chain,mainly rely on the main business cost profit ratio and the industrial added value of these two indicators from the two aspects of each link of the basic development situation and benefit distribution status of detail.On the base of analysis,the construction of CGE model of Yunnan nonferrous metals industry chain to simulate the internal industry chain in the three links,any part of the price changes on the other two aspects of sales and price and influence on the national economy,and calculating the price changes in the industrial influence coefficient changes for the evaluation of the stability of the industrial chain.To construct the industrial chain of the logistic equation in the measure of the target model,dissipative structure theory in the determination of instability for the industrial chain of stability is calculated.In terms of non-ferrous metals industry chain efficiency estimating,network DEA model is calculated for the development of the production frontier in Yunnan non-ferrous metals industry chain.Finally,the linkage mechanism and mechanism building on the target of combination,stable and efficient is made to achieve desired variables specific changes in value and the price as the carrier of simulated price changes in the realization of the target value.This research shows that,from the current situation,Yunnan non-ferrous metal industry chain has been formed,and there are large enterprises,including three links.Although the development of Yunnan non-ferrous metal hold the advantage in reserves,hydropower and other fileds,but has the problem because of the high cost,processing technology that ags behind.Since 2011,the main business profit rate of the three links is in a state of decline,while the industrial added value has increased,but from 2008 to 2011 this 4 years has a smaller increase,this will be a challenge to the new position of non-ferrous metal industry in the background of economic development in Yunnan province.The internal links of the industrial chain,from 2005 to 2012,mining industry profit rate is greater than the serious smelting,and than processing,the average ratio of about 46:12:5,the proportion of the added value of the internal sections(containing a worker,net production tax,operating surplus,depreciation of fixed assets)is slightly different,relatively speaking,the depreciation of fixed assets proportion is relatively high.Through the mechanism and quantitative target the change of price is small with the industry influence coefficient changes,for example,the price changes an average of about 0.009 with the influence coefficient changes.When the price of mining and smelting industry product changes,there will be a large influence to the sales of the mining industry,while,when the processing industry price changes,the sales of processing will changes most about 1.2 times compared to the original value.The results show that if the industry chain prices in 30% floating up and down,non-ferrous metal industry chain is in a stable state based on the 2012 datas,which can automatically return to the initial state.The efficiency results show that the non-ferrous metal industry chain in the three links,and the development of smelting and processing industry is relatively inefficient,the whole industry chain have a lot of room to improve.Through putting the quantitative of this object into the mechanism model,we can obtain that the prices of the three links should be increased by 5.6%,3.5% and 3.7% for the realise of the non-ferrous metals industry chain stable and efficient implementation based on the datas of 2012,according to this result,this paper will put forward some relevant countermeasures and suggestions. |
