Following Jiang et al.( 2024), we divide the north and south regions by the Qinling-Huaihe Line to examine the differences in the air quality improvement effects of EBDC in the cities in the south and north. We re-estimate model (1) for the two subgroups separately and present the results in Panel B of Supplementary Table S9. The coefficient on EBDC is negative and significant in north cities (-1.933, t = -2.28 in Column (1)) and insignificant in south cities (-0.103, t = -2.21 in Column(2)). These findings suggest that the improvement effect of EBDC on urban air quality is more significant in northern cities dominated by fossil fuel consumption.]"The original version of this article has been updated.for a reason not seen here, please contact the journal's editorial office.
