| Energy shortages and the steady rise in oil price have affected the country's political security and economic development. The development in energy is hardly in line with the development of environment in China, which is mainly manifested in the serious waste caused during energy production process and the resulting serious energy shortages and environmental problems. Particularly since the beginning of the 21st century, China has entered the golden era of accelerated development. Industrialization and urbanization speed up, and energy and environmental issues have become increasingly prominent. Coal Chemical Clean Coal Technology is developed in this context. The coal chemical eco-industrial park is an important form of developing coal chemical industry in China since it is the optimal operational way to improve energy efficiency, reduce environmental pollution, and protect the ecological environment. The construction level of industrial park is the core measure to evaluate the coal chemical eco-industrial park. Therefore, this paper has great theoretical and practical value for the building of coal chemical eco-industrial park. Currently the evaluation system of coal chemical eco-industrial park is still under development. This paper, based on the theory development and practices in the coal chemical eco-industrial park, researches on how to develop the coupling of coal-chemical enterprises and the evaluation system of industrial park construction level.This paper's main content and contributions lie in the following:1. This paper expounds the coal chemical eco-industrial park construction theory based on the international eco-industrial park development status and practice. It also studies the principle, content and steps of the coupling of coal chemical eco-industrial park enterprises. NM coal chemical eco-industrial park is taken as an example of the establishment of ecological industrial network, which lays the groundwork for Eco-Industrial Park economic analysis.2. A more detailed analysis of the economic benefits for the coal chemical industry eco-industrial park is completed through specific steps and flow analysis model. The results of analysis in eco-industrial park network can manifest that the establishment of Eco-Industrial Park can bring huge economic, environmental and social benefits, which paves the way of coal chemical eco-industrial park construction level evaluation from those three aspects.3. By reference to various standards and summing up a lot of information at home and abroad, this paper establishes the coal chemical eco-industrial park construction level evaluation system according to the characteristics of coal chemical industry. It also determines the weights of evaluation indexes by using entropy method and experts scoring method. On this basis, it builds up the fuzzy comprehensive evaluation model and applies it in conducting analysis to instance in reality. At last, the paper proposed suggestions on how to improve the construction level of NM coal chemical eco-industrial park. |
