Research On The Balanced And Sustainable Development Of The Energy-Economy-Environment System

In the Energy-Economy-Environment system, sustainable energy is the foundation, sustainable environment is the condition, and the sustainable economy is the ultimate goal. Balanced, sustainable development is the People-Centric scientific development, which requires the compound system of Energy-Economy-Environment to develop steadily and healthily, the balanced development of the overall system is important to the transformation of our national economic development pattern and the realization of the whole society's sustainable development . Based on the analysis of the theory of balanced ,sustainable development , this context comprehensively uses qualitative and quantitative methods,focusing on the research of mode about Energy-Economy-Environment system's structure , components, functions, operating mechanism, the cause-effect relations and the main problems such as the feedback loop, making every effort to provide scientific theoretic foundation and applicable operation.The main innovation of this context lies in the following three aspects:First, it constructed a general framework of the Energy-Economy-Environment system. Using the method of systematic dynamics,it put forward that the system is a compound system generated under particular ecological, economic, social, systematic background and combined all kinds of energy, economic and environmental elements. This system is composed by five branch systems:economic-driven system, energy-support system, environment-bearing system, social-developing system, policy-control system, each system contains several components. The five systems couples and restrains mutually.Second, it set up simulated model of the operation of the Energy-Economy-Environment system.It drew the model picture of the structure of this system and constructed the simulated model. By using Vensim PLE software, meanwhile, it carried out a mock test. Using this model predicated and analysed the future development of Hebei province's Energy-Economy-Environment system, it also gave related advices.This analysis provided practical method for the sustainable development of the Energy-Economy-Environment system in Hebei province. It found out the way of searching the operating mechanism of the Energy-Economy-Environment system through qualitative and quantitative method. Through observing the characteristic of the operation of this system, this analysis found the feedback loop which playing the main role and the policy functioning point, providing foundation for Hebei province in making Energy-Economy-Environment developing policy.Third, it established the best solution of realizing the Energy-Economy-Environment system's sustainable development. According to the established principle of controlling variable, it combined with the natural process of the simulation system, choosing several index as the controlling-variables, selecting value through adjusting the constants and the table function. It established the best solution by setting four scences of these time period:the "eleventh five-year period","the twelfth five-year period" and time during 2016 to 2020, providing reference for the government when making policies, provide feasible suggestions to the realization of this Energy-Economy-Environment system's balanced and sustainable development.The research discovery has a certain practical guiding meaning to our national Energy-Economy-Environment system's balanced and sustainable development, meanwhile,the train and way of though of this context provide reference to the research of other social and economic problem.
