Industrial Enterprises Safety Input And Output Analysis Based On Ecological Economy Theory

As a business enterprise, how to implement safe investment reasonably is an urgent problem which needs to be solved in the process of its development. However, in our country safety economic formation and its development process, due to the influence of many factors, there are a large number of acute and complex ecological and economic problems; they are mainly manifested in environmental pollution, ecological damage, resource depletion, economic recession and other issues, and with the development of economy, the contradiction of ecological economy is increasingly serious. Eco-economic issues must be considered when companies implement safe investment in the grim reality. Enterprise's safety investment considering the ecological and economic problem is a huge system project, with a long-term and arduous, and its complexity and abundant connotation. But its core problem is the coordinated development of ecological and economic, this is also the essence of ecological economics theory.In a safe investment how to coordinate social, economic and ecological development relations, and seek enterprises'benefit maximization, has become an important subject which is concerned in today's society, this is precisely resolved around this issue, it will introduce safety ecological economics, economic theory, the use of qualitative analysis combined with quantitative analysis, a combination systems analysis method of normative analysis and empirical analysis-depth researching the theory, methods and means of safety investment.Firstly, research development is summarized in this field at home and abroad, the concept of safety investment and ecological economy theory is defined, ecological economy theory is put forward based on the theory of basic economic security, the similarity and differences between safe economy and ecological economy are analyzed systemically.Secondly, under the principle of safety index system is established, safety investment index system is established too. The index weight is determined by AHP method. Because it is very limited that safety investment evaluation model method at present, this paper attempts to use knowledge of BP neural networks, genetic algorithms to establish an assessment model of safety investments, it provides theoretical basis for enterprises safety investment.Lastly, in this paper, a corporation in city is researched empirically in safety production and investment by this model, actual results show that, it is feasible to use neural network model, establishment of evaluation model has a direct and important practical significance for the promotion of enterprises to improve the scientificity of safety investment.
