我国资源型城市碳排放配额分配研究——基于H-CSW-DEA模型

Research on Carbon Emission Quota Distribution of Resource-based Cities in China:Based on H-CSW-DEA Model

产业结构偏重、能源结构偏煤的资源型城市是碳排放的重要特殊主体,同时肩负着国家能源资源安全保障的历史使命,其能否同步达峰对国家双碳战略目标实现至关重要,这其中碳排放配额分配是首要关键问题,也是环境经济学研究的热点问题。本文以我国116个地级资源型城市作为研究样本,创新性地提出H-CSW-DEA模型对城市碳排放配额的初始分配进行测度,运用PSM-LinkDEA进行桥接,从整体层面、典型资源型城市、区域异质性、类型异质性对结果进行深度对比讨论。研究发现,整体资源型城市碳排放配额均为正,且根据碳排放配额划分标准,资源型城市的数量大致呈现正偏态分布;不同地区的资源型城市碳排放配额分配存在异质性,即东部地区>中部地区>西部地区;资源型城市各类型碳排放配额分配存在异质性,即再生型>成熟型>衰退型>成长型。本文最后从推动产业结构能源结构优化升级、优化绿色低碳发展区域布局、因地制宜明确碳减排量化目标三方面提出了政策建议。本文结论对于环境经济学中关于碳排放配额的相关研究作出补充,对各资源型城市明确自身现状、制定科学合理的碳减排路径具有一定政策启示。

Resource-based cities with heavy industrial structure and coal-based energy structure are important special actors of carbon emissions.At the same time,they shoulder the historical mission of energy and resources security.Whether they can reach the peak synchronously is crucial to the realization of the national carbon peak and neutrality strategic goals.The allocation of carbon emission quotas is the primary key issue,and also a hot issue in environmental economics.In this paper,116 prefecture-level resource-based cities in China are taken as the research samples,and the H-CSW-DEA model is innovatively proposed to measure the initial allocation of carbon quotas,and PSM-LinkDEA is used to bridge.The results are compared and discussed in depth in terms of the overall level,typical resource-based cities,regional heterogeneity and type heterogeneity.It is found that the overall carbon quota of resource-based cities is positive,and according to the classification standard of carbon quota,the number of resource-based cities generally presents a positive skewness distribution.The carbon emission quota distribution of resource-based cities in different regions is heterogeneous:eastern region>central region>western region.The distribution of various types of carbon quotas in resource-based cities is heterogeneous:renewable>mature>recession>growth.Finally,this paper puts forward policy suggestions from three aspects:promoting the optimization and upgrading of industrial structure and energy structure,optimizing the regional layout of green low-carbon development,and clarifying the quantitative goals of carbon emission reduction according to local conditions.The conclusions of this paper supplement the relevant research on carbon quota in environmental economics,and have important policy implications for each resource-based city to clarify its own status and formulate scientific and reasonable carbon emission reduction paths.
