Environmental problems are becoming increasingly serious.The relationship between economy and environment is widely concerned by government,enterprises and academia.However,the existing researches seldom involve the relationship to the guidance and application in the micro level of enterprises.The increasingly strict environmental policies affect the macro and micro environment of enterprise development,which makes new demands on the adjustment or selection of enterprise strategies.How to realize economic and environmental benefits in the changing environment can affect the sustainable development of enterprises,which is of great significance to the cultivation and acquisition of enterprise competitiveness and environmental competitiveness.From the perspective of economic and environmental relationship,the dissertation uses the method of speculative research,from the micro model analysis to the macro analysis of enterprise growth environment and to the micro analysis of enterprise competitiveness improvement path under the environmental protection trend,analyzing four kinds of models on measuring relationship between economic and environmental that are representative and widely applyed with relevant indexes,which are Endogenous Economic Growth Models,the Environmental Kuznets Curve Models,Multi-objective Linear Programming Models and Input-Output Models,mining demand that these indexes imply for the coordinated development of the economic and environmental systems.On this basis,the dissertation further judges the changes of enterprises’ growth environment caused by the problems of relationship between economic and environment today.The changes are reflected in four aspects.One is the change in the cost of enterprises,including raising the cost of enterprises and promoting the concept of whole-life cycle cost based on environmental protection.One is the change of the production and operation modes of enterprises,including the development of circular economy and remanufacturing industry,and the advocacy and development of the third party governance model of environmental pollution.One is the demand for product innovation,which comes from the demand change caused by the public environment preference and the competitiveness formation of enterprise entry barrier.One is environmental protection makes the industry and the product optimize and upgrade.Based on the above changes,this dissertation proposes the analysisframework of enterprises environment changes based on economic and environmental relationship measurement models.Finally,it puts forward the improving path of enterprise competitiveness and speculative process framework under the dynamic changes of environment enterprises from the aspects which are the influence of environmental regulation policies on strategic choice and behavior of enterprises,the choice of enterprise environment strategy,relying on environmental technology innovation to achieve cost leadership and differentiated competitive advantages,implementing comprehensive environmental quality management,implementing the clean production and control considering the whole process based on environmental protection.The dissertation expands the research field of which economic development and environmental relationship measurement results are applied to micro-level of enterprises,and provides the path reference for how to make full use of the opportunities brought by environmental change under the tight environmental policy,avoid the elimination threats and achieve sustainable development for the enterprises. |
