Transforming the Energy Economic System with the Carbon Neutrality Goal:How Much can the Carbon Pricing and Renewable Energy Policy Contribute?
The transformation of the energy economic system is the key to carbon neutrality,and the contradic-tion between the requirement of carbon neutrality for economic transformation and its requirement of energy system transformation is an urgent issue that needs to be addressed at present.A computable general equilibrium(CGE)model is developed to analysisthe impacts of different low-carbon policies on China's energy consump-tion and power generation structure in the long run.In order to characterize the energy system in China,the model in this study is enriched by endogenous technology improvement of renewable energy and substitution of different power generation technologies based on a Logistic model.The results show that while the carbon pric-ing and renewable energy subsidy policies have different advantages in realizing decarbonization of energy system and short-term optimization of energy structure,the combination of the two policies has lower macroeconomic costs and more significant effect on carbon emission mitigation than a single policy.The results indicate that it is difficult to achieve carbon neutrality only by the decarbonization of the energy system,and the difficulty in achieving carbon neutrality in the later period of 2020-2060 will mainly exist in the basic industrial sectors and the transportation sector.
