| 中文摘要 |
| 基于2006~2020年282个地级及以上城市的面板数据,在运用包含非期望产出的超效率SBM模型测度碳排放效率的基础上,利用双重差分模型探究了以《全国资源型城市可持续发展规划（2013~2020年）》（简称《规划》）为代表的区位导向型发展政策对碳排放效率的影响效应及动态表现,并基于产业结构升级视角揭示其内在作用机制,进而对《规划》的异质性效应进行了考察. 结果表明：①《规划》能够显著提升资源型城市的碳排放效率约0.043个单位,且这一结论在经过PSM-DID等方法检验后依然稳健. 但从动态效应来看,上述影响存在一定的时滞性,且呈现出先强后弱的动态变化特征. ②机制检验发现,推动资源型城市产业结构高级化、合理化与生态化是《规划》提升碳排放效率的内在作用机制. ③异质性分析显示,《规划》对东部地区资源型城市碳排放效率的提升作用明显大于中西部地区,且该正向效应仅在成熟型、衰退型和再生型城市中显著. 进一步,产业结构升级机制的存在与否是造成上述差异的重要来源. 研究结论可为资源型城市提升碳排放效率,助力我国“双碳”目标实现以及推进低碳转型发展提供一定的政策启示. |

| Based on panel data from 282 prefecture-level and above cities from 2006 to 2020 and using the super efficiency SBM model with unexpected output to measure carbon emission efficiency, this study explores the impact and dynamic performance of location-oriented developmental policies represented by the “National Resource-based City Sustainable Development Plan （2013-2020）” （referred to as the “Plan”） on carbon emission efficiency using a double difference model. The internal mechanism of the Plan is revealed from the perspective of industrial structure upgrading, and the heterogeneity effect of the Plan is examined. The results showed that： ① The Plan could significantly improve the carbon emission efficiency of resource-based cities by approximately 0.043 units, and this conclusion remained robust after being tested by methods such as PSM-DID. However, from the perspective of dynamic effects, a certain degree of time delay was observed in the above effects, and they exhibited a dynamic change characteristic of being strong first and then weak. ② Mechanism testing found that promoting the supererogation, rationalization, and ecologicalization of the industrial structure of resource-based cities is an inherent mechanism for the Plan to improve carbon emission efficiency. ③ Heterogeneity analysis showed that the improvement effect of the Plan on carbon emission efficiency of resource-based cities in the eastern region was significantly greater than that in the central and western regions, and this positive effect was only significant in mature, declining, and regenerative cities. Furthermore, the existence of the mechanism for upgrading the industrial structure is an important source of the aforementioned differences. The research conclusions can provide certain policy insights for resource-based cities to improve carbon emission efficiency, assist in achieving China's dual carbon goals, and promote low-carbon transformation and development. |
