Abstract

This paper investigates the effect and transmission mechanism of air pollution on urbanization based on data from China’s 107 cities during 2005–2018. In order to identify the impact of air pollution on China’s urbanization, we utilized night light data to represent the level of urbanization and used temperature inversion as an instrumental variable to mitigate endogeneity within the two-stage least squares framework. The results suggest that air pollution significantly slowed China’s urbanization process with economic growth acting as the transmission mechanism. The heterogeneity analyses revealed that air pollution had a greater negative impact on urbanization in northern regions than that in southern regions, and a greater negative impact in resource-oriented cities than that in non-resource-based cities. We also find that air pollution was to the detriment of urbanization in larger cities, which have more than 3 million residents, while it did not have a significant impact on Type II large cities, which have fewer than 3 million residents.

空气污染对城市化的影响：中国城市层面的证据

本文基于 2005-2018 年中国 107 个城市的数据，研究了空气污染对城市化的影响及传导机制。为了识别空气污染对中国城市化的影响，我们利用夜光数据来代表城市化水平，并在两阶段最小二乘法框架内使用温度反演作为工具变量来缓解内生性。结果表明，空气污染明显减缓了中国的城市化进程，而经济增长则是城市化进程的传导机制。异质性分析表明，空气污染对北方地区城市化的负面影响大于南方地区，对资源型城市的负面影响大于非资源型城市。我们还发现，空气污染不利于人口超过 300 万的大城市的城市化，而对人口少于 300 万的二类大城市影响不大。

期刊介绍： The Chinese Journal of Population, Resources and Environment (CJPRE) is a peer-reviewed international academic journal that publishes original research in the fields of economic, population, resource, and environment studies as they relate to sustainable development. The journal aims to address and evaluate theoretical frameworks, capability building initiatives, strategic goals, ethical values, empirical research, methodologies, and techniques in the field. CJPRE began publication in 1992 and is sponsored by the Chinese Society for Sustainable Development (CSSD), the Research Center for Sustainable Development of Shandong Province, the Administrative Center for China's Agenda 21 (ACCA21), and Shandong Normal University. The Chinese title of the journal was inscribed by the former Chinese leader, Mr. Deng Xiaoping. Initially focused on China's advances in sustainable development, CJPRE now also highlights global developments from both developed and developing countries.
