Abstract
Given that the Beijing-Tianjin-Hebei Region and its surrounding areas are one of the key areas for air pollution prevention and control in China, testing the impact of air quality on the relationship between new-type urbanization and carbon emission intensity is related to the sustainable development of the region. Based on the panel data of the Beijing-Tianjin-Hebei Region and the surrounding "2+26" cities from 2009 to 2021, the nesting weight matrix of air quality distance was constructed, and the internal relationship was tested with the help of the spatial Dubin model and the threshold effect model. The research results showed that: ① The new-type urbanization in this region had a strong inhibitory effect on carbon emission intensity. ② The new-type urbanization development had a significant positive space spillover effect on the carbon emission intensity in the adjacent areas. The air quality distance was the main factor affecting space overflow, but the influence degree was less than the adjacent distance. ③ The inhibitory effect of the new urbanization on carbon emission intensity and air quality was the threshold variable. Based on this, suggestions were put forward to promote the coordinated development of new-type urbanization and carbon emission reduction, strengthen cross-regional coordination of cities, and strengthen the management of air quality standards.
