Study On The Resources Constraint On Non-Ferrous Industry Of China

At present, the deficiency of non-ferrous resources, especially copper resources in our nation threatens national resources security and certainly influences the economic growth. In the resources supply situation, it is urgent and important to recognize and to solve the copper resources constraint on the copper industry and even on the economic growth of our nation.In this dissertation, the author applies innovatively theory of constraint and theory of rationalization of industry to analyze and judge systematically the constraint link in copper industry. By constructing the Cobb-Douglas production function, the author discusses the relation between input and output of copper industry and reveals the origin and mechanism of resources constraint, qualitatively and quantitatively. The dissertation has an instructional meaning for researching on other natural resources. This dissertation brings forward main conclusions as follows:1. The structure of copper industry is irrationality. Mining industry is a constraint link of copper industry.2. The percentage of leave unused production (PLUP) and the percentage of importing material (PIM) are two available indices used to measure the degree of copper resources constraint on copper industry. The PLUP and PIM of Refined copper is separately 19% and 65% in 2002. As another index, the elasticity coefficient of GDP and refined copper consummation (ECGRCC) is adopted to illustrate the degree of the weak link constraint on the economic growth of our nation. The ECGRCC is 0.88 in 2002.3. The origin of resources constraint of copper industry is mulriple. But the deficiency of copper resources plays a dominant role in causing the constraint.a. On the condition of current economy and technology, the characteristic of domestic copper resources is a decisive factor that causes the constraint.b. Regarding the degree of technology progress of three successive links of copper industry, the highest is smelting industry; on the contrary, the lowest is the mining industry. Mining industry is labor-intensive, while smelting and manufacturing...
