| 在推进制造强国战略实施与生态文明建设的双重背景下,明晰区位导向型产业政策的减污降碳协同效应具有重要的现实意义.基于2006~2021年282个地级及以上城市的面板数据,以“中国制造2025”试点示范城市建设（简称“示范城市建设”）作为准自然实验,利用渐进双重差分模型考察区位导向型产业政策对减污降碳协同治理的影响效应、内在机制及异质性表现,并进一步探究其减污降碳协同所产生的经济社会效益.结果表明：①示范城市建设分别使得示范城市的PM2.5浓度与CO2排放量年均降低2.665×10-3 μg·L-1与3.510×106 t,减污降碳协同水平年均提高0.027个单位,发挥减污降碳协同治理效应,且这一结论在经过内生性处理和多轮稳健性检验后依然成立.②内在机制检验发现,示范城市建设能够通过规模效应、技术效应以及结构效应,进而推动减污降碳协同治理.③异质性分析显示,示范城市建设有助于中西部城市与非资源型城市实现减污降碳协同治理,东部城市仅降碳而不减污、资源型城市仅减污而不降碳,尚未形成协同治理效果.④进一步研究表明,示范城市建设减污降碳协同效应的发挥还能带来约为1 209.057亿元的经济社会效益.因此,贯彻减污降碳协同治理理念,总结试点城市建设经验,探索城市减污降碳协同治理的多维驱动路径,因地制宜,完善区位导向型产业政策的设计细则与执行思路,可为城市减污降碳协同治理精准赋能. |

| In the context of promoting the implementation of the manufacturing power and the construction of ecological civilization, clarifying the synergistic effect of location-oriented industrial policies in reducing pollution and carbon emissions is of practical importance. Based on panel data of 282 prefecture-level or above cities from 2006 to 2021 in China, this study used the “Made in China 2025” pilot demonstration city construction （referred to as “demonstration city construction”） as a quasi-natural experiment and used a difference-in-differences method to examine the impact effect, internal mechanism, and heterogeneity of location-oriented industrial policies on collaborative governance of pollution and carbon reduction and further explored the economic and social benefits generated by its collaborative governance effect. The results show that： ① Demonstration city construction resulted in an average annual reduction of 2.665×10-3 μg·L-1 and 3.510×106 t of PM2.5 concentration and CO2 emissions, respectively, and an average annual increase of 0.027 units in the collaborative level of pollution and carbon reduction, forming a collaborative governance effect. This conclusion was still valid after endogeneity treatment and multiple rounds of robustness testing. ② The internal mechanism test revealed that demonstration city construction could promote collaborative governance of pollution and carbon reduction through the scale effect, technique effect, and composition effect. ③ Heterogeneity analysis showed that demonstration city construction could help central and western cities and non-resource-based cities achieve coordinated pollution and carbon reduction governance. Eastern cities only reduced carbon without controlling pollution, whereas resource-based cities only controlled pollution without reducing carbon and had not yet formed a collaborative governance effect. ④ Further research indicated that the collaborative effect of demonstration city construction in reducing pollution and carbon emissions could bring about economic and social benefits of approximately 120 905 billion yuan. The research showed the necessity to implement the concept of collaborative governance for pollution and carbon reduction, summarize the experience of pilot city construction, explore multidimensional driving paths for collaborative governance of urban pollution and carbon reduction, adapt to local conditions and times, and improve the design rules and implementation ideas of location-oriented industrial policies, which can accurately empower urban pollution and carbon reduction collaborative governance. |
