Research Of The Refine Sugar Ecology Industry Chain Optimizing

Since 20th century, the speedy economic growth characterized by high investment, high consumption and high emission is restricted due to the resources shortage and the environment capacity. The ecological security of the entire humanity will be threatened because of the weakening ecological bearing capacity. How to solve the contradictions of resources, environment and the rapid economic growth are common challenges for human society. Under this background, our difficult problems can be fundamentally solved and our sustainable path of economic effectiveness, low environmental pollution, low energy consumption and social concordance can be guaranteed only by establishing a new development concept and using new economic development models-Eco-Industrial Systems.The extensive economic development ways have been following continuously in the sugar-refining industry. For long time, driven by the economic benefits, some regions and enterprises pursued a partial and short-term target under the traditional developing patterns. This practice caused more rigorous problems in resources, environment and ecosystem, etc. In order to solve these problems this paper attempts to explore the circular economy development patterns that adapt to sugar refining industry by analyzing the theoretical foundation and practice of circular economy, thus breaking the dual crisis of fragile eco-environment and economic poverty, to realize the sustainable development of nature, society and economy systematically.This dissertation combines cyclical economic theories with system theory, ecology, ecological economics, environmental economics, source economics, cleaner production theory, and industrial ecology. The dissertation builds up a theorectical frame system of circular economy, developes the circular economy theories, and enriches the contents of the sustainable development. Through the analysis of the international and local practice of circular economy, the dissertation provids theories and practice foundation for choosing the development patterns of circular economy in sugar-refining industry. Using quantitative analysis and qualitative analysis, based on eco-sector chain theories and practices, the dissertation studies the relative models of cyclical economy in sugar-refining industry by analyzing the influence of industrial structure on resources use and eco-environment. This dissertation is divided into seven chapters. The basic train of thought in this research is according to the requirements of "the new industrialization path", taking rapid development as the subject, taking optimizing the structure as the main thread of the research, combing realizing the upgrading of industrial structure optimization with protecting and optimizing the ecological environment organically, and transforming the advantages of resources and environment into the superiority of industry economy.The first chapter introduces the background and significance of the study, the current research in cyclical economy both at home and abroad, and reviews the literature on the theories of environment economy, eco-economy, and cyclic economy.The second chapter presents the theorectical bases of sugar-refining sector chain optimization. This chapter firstly introduces some basic theories of cyclical economy including the theories of ecology, cleaner production, zero emission theory, and sustainable development, which provide theory support to the specific practice of cyclical economy. Then introducing the theories of industrial chain and industrial structure, including industrial cluster theory, industrial structure upgrading theory, and industrial chain integration theory, etc., discussing the interaction relations between the industry chain and industrial structures.The third chapter analyzes the present development situations of China's sugar-refining industry chains. This chapter makes a deeper analysis of the present existing industrial chain link of sugar-refining industry in our country and points out its flaws and shortcoming against the elementary cyclical economy theories and referring to the overseas experience.The fourth chapter analyzes the optimization of sugar-refining ecological industry chain based on the cyclical economy. This chapter focuses on the development of eco-industrial chains, which is the key issue that this dissertation wants to deal with. Firstly, the dissertation analyzes the ecological industry chain, on this basis, analyzing the patterns of ecological industry parks, discussing the methods of measuring the waste from the ecological industry chains, establishing internal cost model, analyzing and evaluating the economy of sugar-refining ecological industrial chains from the micro point of view, according to this model making a comparative analysis of the internal costs between the new technology and old technology. Lastly, this chapter explains the the concrete application of material balance methods in optimizing the ecological industry chain and discussing the sugar-refining ecological industry chain from microscopic and macroscopic two-dimensional yardsticks.The fifth chapter constructs a target appraisal system of optimizing the sugar-refining ecological industry chain according to the construction principles of target appraisal system.The sixth chapter deals with application analysis-taking the sugar-refining industry in Guangxi as an example. This chapter analyzes empirically the benefits of the sugar-refining ecological industry chain in Guangxi province using Guigang Ecological Industrial Park as an example for the optimization of sugar-refining industry chain in Guangxi; according to the forecasting model of ARIMA (2,1,2), the the benefit value of sugar-refining ecological industry chain in Guangxi is quantified in this chapter, and evaluating the results of the optimization of sugar-refining industry chain.The seventh chapter deals with the market mechanism and government behavior in optimizing the sugar-refining industry chain from the perspective of cyclical economy. This chapter discusses the different roles that market mechanism and government behaviour play in the development of cyclical economy and their interactive relations by using the international experience for reference, putting forward that market mechanism and government behavior should be jointed organically to promote the development of cyclical economy together, and giving specific and well-targeted policy suggestions.The eighth chapter conclusion.this chapter is the conclusion of the second chapter,third chapter, fourth chapter,fifth chapter,sixth chapter and senventh chapter.First,the conclusion,innovative points and significance of the research into management practice are expounded. Second,the limitations of the present study and suggestions for further Studies are explored.
