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.

[京津冀及周边地区新型城镇化对碳排放强度的空间效应]。
京津冀及周边地区是中国大气污染防治的重点区域之一,测试空气质量对新型城镇化与碳排放强度关系的影响关系到该地区的可持续发展。基于2009 - 2021年京津冀及周边“2+26”城市面板数据,构建空气质量距离嵌套权矩阵,并借助空间杜宾模型和阈值效应模型检验其内部关系。研究结果表明:①该地区新型城镇化对碳排放强度具有较强的抑制作用。②新型城镇化发展对相邻区域碳排放强度具有显著的正向空间溢出效应。空气质量距离是影响空间溢出的主要因素,但影响程度小于相邻距离。③新型城镇化对碳排放强度和空气质量的抑制作用为阈值变量。在此基础上,提出了促进新型城镇化与碳减排协调发展、加强城市跨区域协调、加强空气质量标准管理等建议。
