[Coupling Relationship and Interactive Response between Pollution Control and Carbon Emission Reduction and High-quality Economic Development in China's Urban Agglomerations].

The coordinated development of the carbon neutral peak target and dual cycle strategy is an important link to realize the transformation of ecological green and low carbon and also an important carrier of high-quality economic development. Based on the inherent requirements of the synergistic effect of pollution control and carbon emission reduction and high-quality economic development, the coupling mechanism of pollution control and carbon emission reduction and high-quality economic development was discussed. Taking the three major urban agglomerations in China as examples, the comprehensive index system of the synergistic effect of pollution control and carbon emission reduction and high-quality economic development were constructed, respectively. The comprehensive evaluation model, coupling coordination degree model, and panel vector autoregression （PAVR） model were used to empirically analyze the coupling and interaction between the synergistic effect of pollution control and carbon emission reduction and high-quality economic development in the three major urban agglomerations in China from 2010 to 2020. The research showed that： ① The comprehensive development index of pollution control and carbon emission reduction and high-quality economic development showed an overall growth trend. The comprehensive level of pollution control and carbon emission reduction synergy in the Yangtze River Delta urban agglomeration was better than that in the Pearl River Delta urban agglomeration and Beijing-Tianjin-Hebei urban agglomeration. There were significant differences in the level of high-quality economic development among cities, and the overall level was high. ② From the perspective of the coupling relationship, during the study period, the level of reluctant coordination entered the primary coordination level and finally evolved into the intermediate coordination level. The spatial characteristics showed the characteristics of contiguous development centered on cities with higher administrative levels, such as municipalities and provincial capitals. ③ From the perspective of the dynamic relationship, there was a positive interaction between pollution control and carbon emission reduction and high-quality economic development, that is, the development of the two could promote each other. The response of pollution control and carbon emission reduction in the Yangtze River Delta and Pearl River Delta urban agglomerations to the positive impact of high-quality development was higher than that in the Beijing-Tianjin-Hebei urban agglomeration.
