中国的气候变化政策关注程度与林业碳汇增长

Forest carbon sinks play an important role in climate change mitigation and adaptation.The Chinese government has demonstrated its proactive approach in addressing climate change by setting development targets for low-carbon transformation and making solemn commitments to peak carbon emissions before 2030 and achieve carbon neutrality by 2060.In this article,the Chinese Government's Work Reports and Five-Year Plans were used to construct an index named ??????????,which reflects the government's emphasis on climate change and forestry in China.This paper aims to examine the impact of the ??????????,the adjusted Climate Policy Uncertainty(??????)index from the U.S.,or the Economic Policy Uncertainty(????????)index from China on the Chinese forest carbon stocks(??????),comprehensively.On this basis,we are interested in clarifying the channels that promote the growth of forest carbon sequestration in China.Specifically,a panel data from 30 provinces in China from 2000 to 2017 is used for empirical analysis,and the following results were obtained:(1)The baseline regression indicates that ??????????significantly promotes the growth of ??????,while ??????or ????????inhibits its growth.(2)The interactive regression shows that the promoting effect of ??????????on ??????growth is stronger than the inhibiting effect of ??????or ????????.(3)Mediation analysis documents that ??????????promotes ??????growth by increasing forest tending area,expanding existing forest area,increasing renewable energy consumption,and improving green investment.(4)Heterogeneity analysis reveals a clear differentiation in the impact of ??????????on ??????.Finally,policy implications are proposed based on the results.This article is expected to provide a theoretical basis for the Chinese government to develop relevant policies from the perspective of promoting ??????growth.
