摘要: 在国家积极实施低碳减排政策的背景下,推动长江经济带建设资源节约型、低碳集约型区域对我国早日实现碳中和目标具有重要借鉴意义。论文以引导地区推动绿色低碳发展为目标,基于四阶段DEA(data envelopment analysis)模型测算出碳排放效率,构建碳排放量修正模型,然后在采用ESV(ecosystem service valuation)代表各地区的生态本底构建碳汇量修正模型的基础上,综合考虑了长江经济带不同地区在人口数量、土地面积、科技水平、生态环境状况、经济发展水平等先天禀赋方面的差异性,改进原始碳补偿测算模型,计算得出长江经济带各省市的碳补偿金额,并引入空间自相关分析模型,探究各省市间碳补偿金额的空间相关性。结果表明:1)引入修正系数前后计算所得的碳补偿金额差异明显;2)修正后长江经济带碳补偿金额平均值明显增加;3)长江经济带临近省市之间的碳补偿额度具有紧密的联系且相互影响;4)长江经济带碳补偿支付地区主要分布在长三角,接受地区主要分布在中上游。对此提出政府应构建地区碳排放生态系统服务功能测评机制、碳补偿区域项目综合绩效评估和反馈机制,完善碳补偿横向转移支付制度,加强制度管控,扩大绿化范围,加快产业转型升级和人才培养。

Abstract: Under nation’s proactive carbon reduction policy, construction of resourcessaving and low-carbon intensive Yangtze River economic zone is key for China to reach carbon neutralization. This paper, aiming at green low carbon development, uses four-staged DEA (data envelopment analysis) model to estimate carbon emission efficiency, and establishes a corrected carbon emission model, and applies ESV (ecosystem service valuation) to stand for the ecological baselines. Carbon sink corrected model is constructed based on the variances in population, land areas, technical levels, ecological environment, and economic levels in Yangtze River economic zone. Primary carbon compensation estimation model has been improved to estimate their carbon compensation amounts of provinces (cities) in Yangtze River economic zone. Spatial auto-correlated model is employed to explore their spatial auto-correlation of their carbon compensation amounts. Results show conspicuous variances in carbon compensation amounts between before and after correction coefficients are adopted, largely increased after, and closely connected to each other in nearby provinces. Payers are mainly located in Yangtze Rive delta, and the payees are in the middle and upper-stream. This paper presents suggestions on constructing a servicing function evaluation system of regional ecological system, comprehensive performance evaluation and feedback mechanism of carbon compensation projects, improving transverse paying mechanism of carbon compensation, boosting controls, enlarging greening areas and accelerating industrial transformation and talents cultivation.

Key words: carbon compensation, four-staged DEA model, corrected model, temporal-spatial pattern, Yangtze River economic zone
