The Research Of Iron-Steel Industruy Resource Use Efficient Based On The Circular Economy

With the change of the distribution of global iron-steel industry and the sustain and rapid development of economy, China's iron-steel industry produce capacity has made a rapid growth, this not only change the relation between supply and demand of iron-steel production, which present supply exceeded demand, but also resulted in extremely shortage of resource and energy and a serious pollution of environment, due to the unbalanced technological level of construction projects. The point that how to achieve the coordinate development among enterprise, environment and society, minimize the resource and energy cost, improve the competitive force of enterprise, achieve the sustainable development of iron-steel industry become the priority for the iron-steel industry.Based on the full retrospection of circular economy development history, depend on the objective of circular economy and its basic principle, this thesis focus on the main factors which obstruct the circular economy development and the solution of resource and environmental problems, conduct a comprehensive reflection on circular economy. At the same time, this thesis also study the future developing direction and objective of circular economy as well as the method and route to develop circular economy in term of microeconomic level based upon enterprises'actual situation. The main content of this thesis includes the following sections.â‘ T his thesis conducted a study on the inconsistency and conflict of epistemological basis between circular economy and commodity economy based upon a systematic analysis on the history and present situation of circular economy. Supported by the corresponding argumentation, it gives the viewpoint that no real circular economy would exist as long as it's regarded as a way to realize sustainable development within the system of commodity economy. Then, this thesis get the conclusion that commodity economy is the unique condition to give birth to circular economy depending on the analyzing of the precondition and requirement of establishing circular economy starting from the general principles of social economy evolution. At the end, this thesis studied the reforms that have to be done towards the social economic operational system in the process to breed circular economy, especially analyzed the roles that government and enterprise, who are the dominant players in market economy as well as their necessary behavior adjustment, should play during developing circular economy . â‘¡T aking Pangzhihua Iron-steel Company as an example, this thesis focus on the necessary objective and the practical advantages of developing circular economy in Pangzhihua Iron-steel Company by study the subject taht the enterprise adjust itself to adapt to the variation of operational conditions and to integrate its target with the objective of social development during the developing process of circular economy.â‘¢B y using the model of Data Envelopment Analysis (DEA) , this thesis established a model to evaluate the efficiency of iron-steel enterprise in development of circular economy, which can reflect iron-steel enterprise's redundancy degree, scale efficiency and technical efficiency from the use of electricity consumption, water consumption and mineral resource consumption, and also analyzed the status problem of circular economy. And then, depending on the Analytic Hierarchy Process (AHP) model, the thesis established the evaluation method for iron-steel enterprise's circular economy development evaluation index system to evaluate the Pangzhihua Iron-steel Company's development of circular economy by using the date from 2003 to 2007.â‘£B ased on the conclusions above, this thesis proposed a reasonable solution to the problems of circular economy, including the strategy of technology innovation and system innovation, integrating resource technique use, increasing the efficiency of resource use, promoting the efficient managing exploitation mineral resource, maximizing the cost-effectiveness, establishing a social circular economy system.The conclusions and innovations of this thesis goes as follows:â‘ Construction and application of the evaluation index system for iron-steel enterprise in development of circular economy. By means of Data Envelopment Analysis (DEA) model, this thesis established a model to evaluate the efficiency of iron-steel enterprise in development of circular economy by using the date from 1995 to 2007. And then, by using Analytic Hierarchy Process (AHP) model, this thesis established evaluation method for iron-steel enterprise's circular economy development evaluation index system to evaluate the Pangzhihua Iron-steel Company's development of circular economy. Evaluation of the iron-steel enterprise in development of circular not only determined the level of enterprise in development of circular economy, but also probe into the problem, so it's a very important progress. The before research of evaluation system and evaluation method on this topic are mainly research on the national level, regional level, the assessment of enterprise in development of circular economy is very rare. Therefore, this study on this topic is a new one and can be treated as an innovation;â‘¡Reconstructed the epistemological basis of circular economy. Circular economy is a new economic pattern established on a new epistemological basis ,which means it couldn't be a development model based on the epistemology of commodity economy, and only such economic pattern can adapt to the future ecology civilization; Before replacing commodity economy as the mainstream economic pattern, circular economy shall gradually become mature within the economic ethics, the system basis and the operational mechanism of commodity economy where commodity economy is the soil to breed circular economy and it shall be inevitably replaced by circular economy;â‘¢Explored the status and role of enterprise in the development of circular economy. Confronting serious resource and environmental problems, government, enterprise and social public should adjust their own behavior to fit the needs of developing circular economy. Meanwhile, restrictions must be taken to against the influence from commodity economy in respect to deteriorations of resource, environmental pollution and ecological destruction as we bring the functions of commodity economy to accelerate economic development continuously. As the microeconomic main part under commodity economy, enterprise should be the main force to develop circular economy while both government and social public actively create conditions for enterprise to help enterprise fulfilling such mission. Enterprise should actively adjust its behavior mode to adapt the business environment varied constantly with the development of circular economy.
