Research On Evaluation Of Circular Economy Development Power In Coal Enterprises

Coal, as an important resource in our country, is the cornerstone of social and economic development. Although Coal enterprises have made great contributions to China’s rapid economy growth in past, their traditional extensive exploitation mode caused serious waste of resources and environmental pollution. These problems, coupled with limited coal and non-renewable nature of coal resource, make it an important strategic task for the enterprises to plan the future survival and development. Therefore, the coal enterprises need to adjust and optimize the industrial structure, to achieve sustainable development through a new economic model. Practice has proved that circular economy policy help coal enterprises to realize the resource recycling and saving, to obtain maximum development benefits with minimal resources consumption and minimum pollution, to achieve sustainable development. The decision of circular economy is not only inevitable, but also correct choice for enterprises to implement the strategy of sustainable development to cater for rapid economy growth and to overcome the resource shortage, environmental pollution. In this process, how to vigorously develop the circular economy for coal enterprise characteristics has become a pressing matter of the moment, and how to scientifically evaluate the level of circular economy development and the development of coal enterprises also become an important way to promote the development of circular economy.At present, although the general research achievement of circular economy evaluation is abundant, it is not so for specific study of coal enterprises. How to scientifically evaluate the coal enterprise circular economy development level? To find a solution to the problem, we must in-depth analysis the behavior of the development of circular economy in coal enterprises, and answer the following questions for circular economy in coal enterprises:what is its connotation? how to measure the development level? How to select and evaluate the index system of? How to optimize the evaluation model and so on. This study has important theory significance, since it can enrich and perfect the theory of circular economy evaluation of coal enterprise. The study also has important practical significance:the evaluation analysis scientifically the coal enterprise performance, extract the restricting factors, then provides advice for adjusting the circular economy development planning, and defines focus for decision making. This dissertation responses well to the era’s calling for circular economy in our country. It deepened understanding of the connotation of circular economy theory; put forward the evaluation index system and evaluation methods.Coal enterprises’developments of circular economy, their transformation of economic growth are the research background of this dissertation. The dissertation defined the concept of circular economy development power of coal enterprises; expatiated its connotation, characteristics, functions and operating mechanism; established the circular economy development evaluation index system; proposed the use of analytic hierarchy process, integrated gray correlation method and the TOPSIS model to evaluate the coal enterprise circular economy development. Finally put forward the countermeasures to improve the development of circular economy of coal enterprises. The research content is divided into nine parts; the specific contents are as follows:The first chapter is the introduction, first introduced the research background and significance. Through review of the literature, summarized the main achievements of research on Evaluation of circular economy in coal enterprises and existing problems, points out the evaluation theory and methodological limitations. Based on the shortcomings of previous studies, this dissertation describes the research ideas, research methods and research contents, and the innovation points briefly.The second chapter discusses the theories of the coal enterprise circular economy development power. Mainly includes the system theory, enterprise development theory, sustainable development theory, the circulation economic theory. Based on the theoretical connotation, analyzes the internal relations between these theories and the development of coal enterprises, laid the foundation for the study of the.The third chapter is about the coal resource and its distribution features, development and production, the development of coal demand and consumption situation, analyzes the connotation and characteristics of the development of coal enterprises, expounds the current situation of the development of coal enterprise of circular economy in China and the existing problems:lack of motivation and funds to take circular economy revolution; environmental pollution and ecological destruction due to bad technical support ystem; comprehensive utilization inefficiency of coal resources; low rate of resource recovery; short industry chain; low added value of products; large proportion of small coal enterprises; low market concentration,bad coordination between interpresis; poor safety etc.The fourth chapter is the main part of theoretical research, answer to "why the coal enterprise circular economy development?" This problem, and on this topic related research. First proposed the concept of circular economy development, and analyzes its connotation, and constructed the coal enterprise circular economy development concept model; then describes the characteristics of the development of circular economy force of coal enterprise, carries on the excavation to the function; finally the use of "slope spheroid mechanics model" of its running mechanism analysis.The fifth chapter introduces the index of circular economy development force of coal enterprise construction process. The goal of constructing the index system under the guidance of the principle, design as the yardstick, along the perfect screening indicators to determine the influencing factors, index system hierarchy, the frequency statistics and coefficient of variation of combination and evaluation index of this clue, completing the development of circular economy force of coal enterprise evaluation index system. The index system consists of1target layer, criterion layer,6layer15sub criteria and36indicators, for the development of circular economy of coal enterprises laid the foundation of stress evaluation.The sixth chapter is about optimization of the development of circular economy force of coal enterprise evaluation method. First introduced the general evaluation method, fuzzy comprehensive evaluation method, AHP, grey correlation method, TOPSIS method, data envelopment analysis, neural network method, the basic idea, characteristics, method of calculation steps were compared and analyzed, according to the features of object and evaluate sample data, the introduction of "AHP-GRA-TOPSIS" comprehensive evaluation method". According to the comprehensive weight analytic hierarchy method gives evaluation index, compare the geometry data columns use gray relation analysis method of similarity degree to determine the degree of correlation between samples (scheme), the close degree of each scheme and the optimal solution is given by TOPSIS method, the ranking of the alternatives, and make full use of their respective advantages, overcomes the shortcomings of the existing evaluation, more reasonable evaluation results are given.The seventh chapter is one of the core chapters of this thesis. This dissertation choose justice coal group as the object of study. Firstly, the text introduced the basic situation of the company, then analysis the development of its circular economy, including the experience, implementation effect and the existing problems and so on.Use the "AHP-GRA-TOPSIS comprehensive evaluation method", the appraisal of justice coal group1996-2011sample data. Conclusion:1996～2011justice coal group’s development of circular economy is a low to high rising trend. The six subsystems are graphical analysis on the role of justice coal group of circular economy has a positive effect, strong correlation can be seen between economic growth, social responsibility, environmental support, resource recycling capacity, technology innovation and justice coal group’s development of circular economy; there is significant positive correlation between management and coordination force index did not show and justice coal group of circular economy development.The eighth chapter is the countermeasure research. According to the justice coal group’s development of circular economy evaluation results, puts forward some suggestions to cultivate and promote the development of circular economy of coal enterprises to carry out stress, namely diversification, enhance economic growth; respectively from the perspective of the government and enterprises to strengthen the social responsibility; strengthen the resource exploration, mine water recycling and comprehensive utilization of resources. Means to improve the utilization rate of resources, improve the ecological environment; to speed up technological innovation technological innovation, information technology innovation and technological innovation; improve the cycle of economic system, the establishment of the incentive system of circular economy and talent planning, perfect management system, improve management efficiency.The ninth chapter is the conclusion and research prospect. Summarized the research results achieved, then points out the shortage of this research exists, and the future research prospects.The main innovation points:(1)Put forward a new concept, namely the coal enterprise circular economy development power. While previous research on Evaluation of circular economy of coal enterprises is mainly devoted to measure value, this dissertation proposes a new concept of circular economy development power of coal enterprise, and has carried on the definition and system analysis.Circular economy development power of coal enterprise is the comprehensive ability under the guidance of the theory for enterprise to survive and develop while adapting to internal and external conditions, keeping frugal for resource and friendly to environment. This concept is objective, comprehensive, dynamic, compatible, and scalable. The power value, which derived from circular economy development evaluation, has the functions of diagnosis, guidance, encouragement, identification and leading. On this basis, build the concept of circular economy development force of coal enterprise model composed of "six force"; analyzed its running mechanism using slope spheroid mechanics theory. This is the main theoretical innovation, which provides a new idea for the development of circular economy in coal enterprises.(2) Constructs a set of evaluation index system of circular economy development of coal enterprises. While the previous works mostly build a structural framework of three levels, this dissertation presents a new model of four levels, designed on the base of the research of previous literature and expert interview. The structure includes one goal layer,6criterion layers,15sub-rule layers and36indicators. This evaluation index system structure is more perfect. It has been found that the development of circular economy in coal enterprises is affected by economic, social, environmental, resource, technology and management etc. factors. That is conducive to a comprehensive, effective, scientific evaluation of circular economy development of coal enterprises.(3) Constructed the integrated evaluation of circular economy development of coal enterprises "AHP-GRA-TOPSIS" comprehensive evaluation model. The Euclidean distance and gray correlation degree of the organic combination, construct a new relative closeness degree to realize the appraisal on the scheme. The new degree reflects the similarity between alternatives and ideal solution and negative ideal solution of the position relations and data curve, the physical meaning is clearer. Use this method to justice coal group1996to the development of circular economy in2011is evaluated, demonstrates the rationality of the theoretical research and evaluation of circular economy development of coal enterprises.
