Zy Lead And Zinc Smelting Business Cycle Model Of Economic Development And Competitive Advantage Analysis

China is the largest production countries for smelting zinc in the world, but it's a high-energy, high-polluting production processes from smelting lead and zinc, with the industrial development and the resources is coming exhausted and the progress of society, people's consciousness is stronger and stronger for conservation of ecology and resource and environmental, so the development of lead and zinc smelting enterprises face the unprecedented pressures from resources and environmental. Therefore, how to find the new competitive business advantage and achieve the Sustainable Development for enterprises in the new era of industrial development, it's the inevitable choice for the lead and zinc smelting enterprises that it will implement development of the circular economy under the double pressure from resources and environmental protection.It's the goal for recycling economy by efficient of resources and recycling , according to the principle of "reduce, reuse, recycle", through the closed circulation of material and energy use with echelon, so that it become an optimal combination of state for economic development and ecological environment, . Circular economy is a new form of economic development, through the development of circular economy can be achieved efficiently resources, recycling, resource and environmental problems to solve. Lead and zinc smelting enterprises are key energy-consuming industries and one of the six in China, through the effective use of resources and the reasonable protection of the environment,, we can enhance the competitive advantage for lead and zinc smelting enterprises. Therefore, under the pressure of resources and environmental protection, lead and zinc smelting enterprises must develop a recycling economy, so that enhance competitive advantage and achieve sustainable development of enterprises.ZY is an important lead and zinc smelting company, is one of the representatives of the domestic lead and zinc smelting joint enterprise. Therefore, the circular economy as the main object of study in this paper, through make in-depth analysis of the definition and origin of circular economy to the development of the theory basis, through the understanding of domestic recycling economy development model, and the theory of the circular economy and competitive advantage, ZY business cycle economic development to an example case studies. Through study the difficulties and problems in ZY enterprise development, to explore strategic business development of circular economy program, and through the business cycle ZY-depth model of economic development research, analysis ZY's ways to enhance competitive advantage. Thus it's an innovative and exploratory research for lead and zinc smelting business cycle model of economic development, and to provide an effective reference.Following major elements:1. Detailed study the theory of the development of circular economy.The definition of circular economy and theories of origin; theory of competitive advantage, and its relationship with the circular economy; the necessity of the development of circular economy for lead and zinc smelting business.2. Detailed study ZY's model of cycle economic development. ZY enterprises through the optimization of human resources; the implementation of direct lead smelting furnace Jifusaite, atmospheric oxygen direct leaching, the method of purification of biological preparation to deal with wastewater and reuse of waste treatment and other technological transformation; create a culture of good corporate strategy for construction of circular economy to achieve circular economy development model effectively.3. Study the source of competitive advantage for ZY enterprise. Through analysed some relevant technical, economic indicators in ZY by the before and after of development of circular economy, to study ZY develop the circular economy to gain the competitiveness of resources available, environmental protection, technology and cost so on.
