This study employs panel data from 30 provinces and cities in China from 2004 to 2019 to empirically estimate the relationship between producer services agglomeration (PSA) and manufacturing carbon emissions. The findings suggest that such agglomeration is beneficial for lowering carbon emissions in manufacturing, and this conclusion passes multiple robustness tests. Heterogeneity analysis results show that PSA in the east and west regions significantly lowers manufacturing carbon emissions, while its impact in the central region is not significant. High-end PSA is beneficial for cutting carbon emissions in manufacturing, but the inhibitory effect of middle- and low-end PSA is not significant. PSA significantly suppresses carbon emissions from capital- and technology-intensive manufacturing, while it has little impact on carbon emissions from labor-intensive manufacturing. Further analysis reveals that PSA has a dual-threshold impact based on absorptive capacity and a single-threshold effect based on infrastructure level on manufacturing carbon emissions. As the absorption capacity crosses the second threshold or the infrastructure level crosses the first threshold, the inhibition effect of PSA on manufacturing carbon emissions begins to become prominent and shows a trend of enhancement. Our research findings provide theoretical and empirical bases for lowering carbon emissions in the manufacturing sector and fostering its ascent to the highest position of the value chain.
本研究利用 2004 年至 2019 年中国 30 个省、市的面板数据,实证估计了生产者服务业集聚(PSA)与制造业碳排放之间的关系。研究结果表明,这种集聚有利于降低制造业的碳排放,这一结论通过了多种稳健性检验。异质性分析结果表明,东部和西部地区的 PSA 显著降低了制造业的碳排放,而中部地区的影响则不显著。高端 PSA 有利于降低制造业的碳排放,但中低端 PSA 的抑制作用则不显著。PSA 显著抑制了资本和技术密集型制造业的碳排放,但对劳动密集型制造业的碳排放影响不大。进一步的分析表明,PSA 对制造业碳排放的影响存在基于吸收能力的双重门槛效应和基于基础设施水平的单一门槛效应。当吸收能力跨越第二个门槛或基础设施水平跨越第一个门槛时,PSA 对制造业碳排放的抑制作用开始变得明显,并呈现出增强的趋势。我们的研究结果为降低制造业的碳排放和推动其向价值链的最高位置攀升提供了理论和经验基础。
