| Carbon emission trading is the main measure to optimize the allocation of carbon emission resources for carbon emission reduction through market mechanism.China learns from the mature system of EU carbon emission trading and actively explores the establishment of carbon emission trading market,adjustment of energy structure and research and development of low-carbon technologies.At present,the national carbon emission trading market is the first to be included in power enterprises,and the pressure of power generation enterprises as the main body of carbon emission increases.It is of great theoretical and practical significance to study the comprehensive impact of carbon emission trading on enterprise economic benefits,energy structure adjustment and development environment,and how power generation enterprises respond to the opportunities and challenges brought by carbon emission trading.In this paper,firstly,the related literatures about carbon emission trading at home and abroad are sorted out,and the related concepts of carbon emission trading are clarified.Secondly,the development status of carbon emission trading market in China’s power generation enterprises is expounded,and the existing problems are analyzed,which provides reference for opening a unified national carbon emission trading market.In addition,SWOT analysis method is used to analyze the strengths,weaknesses,opportunities and risks faced by power generation enterprises under the background of carbon emission trading.Power generation enterprises can adopt optimal strategies for development in internal and external environment.Then,using the system dynamics modeling principle and Vensim software,the internal driving force model of power generation enterprises participating in carbon emission trading and the model of the impact of carbon emission trading on the development of power generation enterprises are constructed,and the case is used for empirical analysis.In this paper,we build a model to study how to reduce production costs,improve enterprise efficiency and promote sustainable development of power generation enterprises in the carbon emission trading market,implement total carbon emission control,encourage enterprises with high carbon emission intensity to carry out technological innovation,and choose low-carbon development.Enterprises with low carbon emission intensity can make profits by selling surplus quota,In general,the goal of reducing emissions and increasing efficiency can be achieved.With the increase of electricity demand caused by the sustained economic growth,carbon emissions will also increase.Balancing the relationship between economic growth and environmental quality has become an urgent problem.Under this background,the carbon emission trading model of power generation enterprises is constructed,which shows that the power generation enterprises participate in carbon emission trading actually comes from the internal driving force,and is verified by carbon trading cost and enterprise benefit cases in different scenarios.In addition,through the model analysis,it is concluded that power generation enterprises should strengthen technological innovation,promote development through innovation,and promote the transition from high carbon emission enterprises to low carbon enterprises.It has become an inevitable choice for power generation enterprises to actively develop new energy and increase the proportion of clean energy.It further shows that carbon emission trading has a positive guiding role for the sustainable development of power generation enterprises in China. |
