ECOLOGICAL ECONOMICS FOR ENERGY CONSERVATION AND EMISSION REDUCTION OF HIGH ENERGY CONSUMING INDUSTRIES BASED ON THEORY OF CIRCULAR ECONOMY

The high energy consumption and the large amount of pollutants discharged by high-energyconsuming industries in the production process have posed a great threat to the ecological environment.This paper takes the theory of circular economy and the basic concept of sustainable development as the research foundation to study energy conservation, emission reduction and eco-economic construction of high-energyconsuming industries; and then it proposes countermeasures and suggestions for the ecological construction and development of such industries.The research shows that the reduction of energy consumption has contributed a lot to the reduction in the total energy consumption and the comparable energy consumption; In recent years, the energy consumption per one ton of steel has been decreasing year by year, and the energy conservation and emission reduction measures such as technological reform, policy regulation and economic coordination have played a major role in it; the energy-conservation and emission-reduction ecoeconomic system based on circular economy can mitigate improve the high energy consumption of the industries, which has laid a foundation for their ecological development.This paper has provided theoretical support and guidance for the energy conservation, emission reduction and the eco-economic construction of high-energy-consuming industries.
