Industrial output and air pollutant emissions: A study of Chinese cities

With data on 287 cities from 2003 to 2010, this study investigates whether industrial firms of different types of ownerships differ in sulfur dioxide emissions across city administrative levels and geographical regions in China. Weighted least square regression results suggest that both Hong Kong, Macau, and Taiwan (HMT) industrial firms and ethnically non-Chinese foreign firms are associated with statistically significant higher sulfur dioxide emissions in municipalities. HMT firms tend to emit less in southern China, where they are close to home, while foreign firms tend to emit less in other regions.

本研究基于2003至2010年287个城市的面板数据，探讨中国不同所有制类型工业企业的二氧化硫排放量是否会随城市行政层级与地理区域的不同而呈现异质性特征。加权最小二乘（Weighted least square）回归结果显示，港澳台（Hong Kong, Macau, and Taiwan, HMT）资本工业企业与非华裔外资工业企业，均与直辖市内统计意义上显著更高的二氧化硫排放量呈显著相关。其中，港澳台企业在邻近其母地的中国南方地区排放水平相对更低，而外资企业则在其余区域表现出更低的排放强度。
