京津冀城市工业对雾霾污染影响的溢出效应——基于制造业投资城市网络的视角北大核心CSCD

工业生产对城市环境质量的影响具有空间溢出效应,但鲜有研究从城市网络的视角探讨城市工业基于产业投资联系对环境污染影响的溢出效应。论文使用2004—2018年京津冀城市间制造业企业投资数据,分析京津冀制造业投资城市网络特征,并创建城市间制造业投资联系矩阵,结合空间计量模型,实证检验基于制造业投资城市网络的京津冀城市工业对雾霾污染影响的溢出效应。研究发现:京津冀城市间制造业互投资中污染型制造业投资增长最显著,且相比于其他类型的制造业投资,污染型制造业投资城市网络更加分散,是造成城市工业对雾霾污染影响溢出的重要渠道。从时空演变来看,京津冀城市间污染型制造业投资城市网络不断扩张,可能造成城市工业对空气质量更广泛的跨地区影响。实证结果验证了城市工业通过制造业投资城市网络带来雾霾污染的空间溢出,这种溢出的传输机制是通过城市间的产业投资联系,且和投资的产业类型有关。相比于其他类型的制造业投资,污染型制造业投资联系造成的雾霾污染溢出效应最强。因此,城市群地区需要统筹协调好城市间的产业发展,才能更有效地应对区域环境挑战。

Spillover effects of urban industries on haze pollution among cities of the Beijing-Tianjin-Hebei region: From the perspective of inter-city manufacturing investment network

In urban agglomerations, the environmental impact of urban industries may spillover between cities not only through the pollution diffusion, but also through the inter-city linkages of industrial investment and transfer. The spillover effect of urban industries on air quality through the urban industrial investment network has been largely ignored in the literature. Due to the urban network externality, the air quality in a city is not only influenced by its own industrial activities, but also closely related to the industrial development of other cities connected through the industrial investment in the urban network. By applying the investment data of manufacturing enterprises among cities in the Beijing-Tianjin-Hebei region from 2004 to 2018, this study investigated the characteristics of the inter-city manufacturing investment network in the region. This study created inter-city manufacturing investment network matrices under a spatial econometric model to empirically test the spillover effect of urban industries on haze pollution via the inter-city manufacturing investment network in the Beijing-Tianjin-Hebei region. The findings suggest that the investment in polluting manufacturing has increased significantly under the mutual investment in manufacturing between cities in the region. Furthermore, compared with other types of manufacturing investment, the polluting manufacturing investment network among cities in the Beijing-Tianjin-Hebei region is more dispersed. Those extensive investment linkages in polluting manufacturing industries between cities in the region are important channels for the spillover effect of urban industries on haze pollution. From the perspective of spatiotemporal evolution, our results indicate that the gradual expansion of the network of polluting manufacturing investment between cities in the Beijing-Tianjin-Hebei region is more likely to generate extensive cross-city environmental impacts. Our empirical results confirm the spillover effect of urban industries on haze pollution via the inter-city manufacturing investment network. The transmission mechanism of this spillover effect is based on the investment linkages between cities and depends on the types of invested industries. Specifically, the polluting manufacturing investment linkages result in more significant and stronger spillover effects of urban industries on haze pollution through the urban network. Therefore, the coordinated development of urban industries among cities in the urban agglomeration is necessary for meeting the regional environmental and sustainability challenges. © 2023, Editorial office of PROGRESS IN GEOGRAPHY.
