文摘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。
