| While the economic grows rapidly,environmental pollution is becoming more and more serious,especially the increase of greenhouse gases,which makes extreme weather phenomenon more frequent.Therefore,all countries also actively respond to the call to reduce carbon emissions,China put forward in the "14th Five-Year Plan" to the realization of the goal of carbon emissions to peak in2030.Therefore,as China’s power industry is a high-energy consumption and high-emission industry,it is of great practical significance to study how China can achieve economic development while reducing the carbon emissions of the power industry and decoupling the two.In this article,through reviewing the related literature,by constructing the Tapio decoupling model,this paper analyzes the decoupling state of China’s power industry carbon emissions and economic growth from 1996 to 2018,establishes a causal chain with the help of the Kaya equation,analyzes the factors affecting the decoupling of power industry carbon emissions,and analyzes the relationship between the power industry carbon emissions and economic growth and power generation energy consumption,and to test the Granger causality between the variables,The decoupling state of the two is predicted by 2030.Based on the conclusions obtained,put forward to reduce carbon emissions and weaken their relationship of the electric power industry related suggestions.The conclusions are as follows:(1)At present,China’s power industry Carbon emissions and economic growth has been in a state of decoupling and both have a half year in the weak decoupling state,and the rest of the years were strong decoupling,expansion negative decoupling and growth connection.The energy conservation elasticity index of the power industry is consistent with and similar to the carbon emission decoupling index.Energy saving is the key to weaken carbon emission and economic growth of the power industry.(2)For carbon emissions of the electric power industry and the relationship between economic gain,both of them have long-term equilibrium relation and short-term fluctuation change,and economic growth and power generation energy consumption are the Granger causes of carbon emissions in the power industry.(3)It is predicted that most of the decoupling state between carbon emissions and economic growth of the power industry in 2019-2030 is in the state of growth connection,the energy saving elasticity index is still the same as the decoupling index,and the power generation energy consumption elasticity index is almost close to the decoupling index. |
