Abstract

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.

[区位导向产业政策对污染和碳减排的协同效应]。
在推动实施制造强国和生态文明建设的背景下,厘清区位导向产业政策在减少污染和碳排放方面的协同效应具有现实意义。本研究基于2006 - 2021年中国282个地级市及以上城市的面板数据,以“中国制造2025”试点示范城市建设(以下简称“示范城市建设”)为准自然实验,采用差中差法考察其影响效应、内在机制、研究区位导向产业政策对污染减排协同治理的异质性,并进一步探讨其协同治理效应所产生的经济效益和社会效益。结果表明:①示范城市建设使PM2.5浓度和CO2排放量年均分别降低2.665×10-3 μg·L-1和3.510×106 t,污染与碳减排协同水平年均提高0.027个单位,形成协同治理效应;该结论经内生性处理和多轮稳健性检验仍然有效。②内部机制检验表明,示范城市建设通过规模效应、技术效应和成分效应促进污染减排协同治理。③异质性分析表明,示范城市建设有助于中西部城市和非资源型城市实现污染与碳减排的协调治理。东部城市只减碳不控污染,资源型城市只控污染不减碳,尚未形成协同治理效果。④进一步研究表明,示范城市建设在减少污染和碳排放方面的协同效应可带来约120,050亿元的经济效益和社会效益。研究表明,有必要落实污染与碳减排协同治理理念,总结试点城市建设经验,探索城市污染与碳减排协同治理的多维驱动路径,因地制宜,与时俱进,完善区位导向产业政策的设计规则和实施思路。精准赋能城市污染与碳减排协同治理。
