城市群多中心一体化发展有利于降低雾霾污染吗？

摘要以中国21个城市群为研究对象,首先从规模、位置以及可达性三个方面对城市群多中心空间结构进行测度,然后采用双向固定效应模型识别城市群多中心空间结构对雾霾污染的影响。其次,从功能、制度、文化三个维度构建指标体系,测算城市群一体化水平。最后,考察城市群一体化水平对多中心空间结构影响雾霾污染的调节效应,即分析在不同的城市群一体化水平下,多中心空间结构对雾霾污染的异质性影响。研究发现:(1)城市群多中心空间结构能够明显缓解雾霾污染。(2)城市群一体化发展对多中心空间结构缓解雾霾污染具有正向促进效应,从功能、制度和文化一体化方面进行分析,结论仍然成立。这意味着加强城市群多中心体系的构建可以缓解经济活动过度集中在单一中心城市而造成的雾霾污染,推动城市群一体化水平的提升能够进一步促进多中心空间结构的减排效应。

Abstract： Taking 21 urban agglomerations in China as the research object, this paper first measures the polycentric spatial structure of urban agglomerations from the three aspects of scale, location and accessibility, and then uses the two-way fixed effect model to identify the impact of polycentric spatial structure of urban agglomerations on haze pollution. Thirdly, the index system is constructed from the three dimensions of function, institution and culture to measure the integration level of urban agglomeration. Finally, the regulatory effect of urban agglomeration integration level on the impact of polycentric spatial structure on haze pollution is examined in this paper, that is, the heterogeneous impact of polycentric spatial structure on haze pollution under different urban agglomeration integration levels is analyzed. The results are as follows: (1) The polycentric spatial structure of urban agglomeration can obviously alleviate haze pollution; (2) The integration of urban agglomeration has a positive promoting effect on the mitigation of haze pollution by polycentric spatial structure. And from the aspects of functional, institutional and cultural integration, the conclusion is still valid. This means that by strengthening the construction of polycentric system of urban agglomeration, we can alleviate the haze pollution caused by excessive concentration of economic activities in a single central city, improve the level of integration of urban agglomerationand further promote the emission reduction effect of polycentric spatial structure.
