| Under the restrictions of relevant provisions such as the Kyoto Protocol and the United Nations Framework Convention on climate change,carbon emission rights have become scarce resources and are endowed with tradable attributes.The carbon emission rights trading market has gradually formed and developed.In 2020,the total amount of carbon emission trading in the world reached 219 billion euros,an increase of 18% year-on-year,and the total amount of carbon emission trading reached an all-time high.As countries around the world pay more attention to the environment,the carbon emission trading market is becoming more and more active.However,the pricing mechanism of carbon emission trading market is vague,and the trading price can not display all trading information,resulting in the insufficient utilization of carbon emission resources.Therefore,the research on the value evaluation of carbon emission rights has important practical significance.The value evaluation of carbon emission rights can provide reasonable pricing reference for carbon emission rights trading,release positive price signals and promote the orderly conduct of carbon emission rights trading.Considering regional factors,this paper uses the improved shadow price method to calculate the internal value of carbon emission rights,provide pricing basis for carbon emission rights trading,and promote the cross regional flow of carbon emission rights resources in the national carbon emission rights trading market.This paper is mainly composed of five parts.Firstly,through the review of relevant research on carbon emission rights,this paper defines the concept of carbon emission rights,relevant elements and theories of value evaluation from the perspective of asset evaluation.Secondly,it introduces the current situation and existing problems of carbon emission trading,analyzes the applicability of the shadow price method to evaluate the value of carbon emission rights,proposes to use the improved shadow price method to build a SBM dual model to evaluate the shadow price of carbon emission rights,and applies the improved shadow price method to the shadow price calculation of carbon emission rights in Shenyang to verify the rationality of the improved shadow price method.Finally,it puts forward suggestions for the value evaluation of carbon emission rights to promote the development and growth of carbon emission rights trading market.This paper uses the improved shadow price method to evaluate the internal value of carbon emission rights,and comes to the conclusion that the value of carbon emission rights is different in different regions,and the transaction price is positively correlated with regional industrial structure,energy consumption structure,economic development and other factors.Moreover,China’s carbon emission trading price is lower than the internal value.We should actively use the market mechanism to improve the carbon emission trading price,reasonably allocate carbon emission rights resources,and realize the "double carbon" goal as soon as possible. |
