碳市场试点政策提高区域碳汇的机理研究OA北大核心CHSSCDCSSCI

In addition to carbon emission trading,carbon market also includes carbon sink trading.A large number of literature have verified that the pilot policy of carbon market can significantly reduce carbon dioxide emissions,but it has neglected to verify its impact on carbon sink.Combined with the characteristic facts of carbon sink trading in China,this paper reveals the impact mechanism of carbon market pilot policy on carbon sink in pilot and non-pilot areas,and uses spatial differential method to carry out empirical analysis.The results show that:compared with the non-pilot area,the carbon sink level in the pilot area is significantly improved;the spatial spillover effect of carbon sink is positive,fiscal environmental protection expenditure is positively correlated with carbon sink,economic development is U-shaped with carbon sink,and urbanization is negatively correlated with carbon sink.Therefore,establishing a more standardized and professional carbon sink trading market,giving full play to the basic role of the market mechanism in the allocation of carbon sink resources,and improving the inter-provincial carbon sink ecological compensation mechanism are effective ways to improve carbon sink.
