As an important cause of global warming, CO emissions have become a research hotspot in recent years. Industrial transfer impacts regional CO emissions and is related to the low-carbon development of regional industries. Taking the Beijing-Tianjin-Hebei region (BTH region) as an example, this study analysed industrial transfer's direct and indirect impacts on CO emissions based on a mediating model and two-way fixed effect panel regression. The results obtained indicate that industrial transfer-in has promoted CO emissions to a small extent, and the positive impact of industrial transfer-in on CO emissions wanes over time. Industrial transfer affects CO emissions by acting on the economic level, on population size, and on urbanisation level, but the indirect effect is weaker than the direct effect. Industrial transfer does not lead to technological upgrading, but the latter is an effective means of carbon emission reduction. Industrial transfer-in has shown a positive effect on CO emissions for most cities, but there are exceptions, such as Cangzhou. In the future, the BTH region should maintain coordinated development among cities and improve the cooperative innovation mechanism for energy conservation and emission reduction.
作为全球变暖的一个重要原因,CO2 排放已成为近年来的研究热点。产业转移影响区域 CO2 排放,与区域产业低碳发展密切相关。以京津冀地区为例,本文基于中介模型和双向固定效应面板回归,分析了产业转移对 CO2 排放的直接和间接影响。研究结果表明,产业转入在一定程度上促进了 CO2 排放,产业转入对 CO2 排放的正向影响随时间逐渐减弱。产业转移通过作用于经济水平、人口规模和城市化水平来影响 CO2 排放,但间接效应小于直接效应。产业转移并没有带来技术升级,而后者是减排的有效手段。产业转入对大多数城市的 CO2 排放都产生了正向影响,但沧州等个别城市除外。未来,京津冀地区应保持城市间的协调发展,完善节能减排协同创新机制。
