Chengdu/Chongqing-Guangdong/Hong Kong/Macao poles are an important part of the national comprehensive three-dimensional transportation network construction. Taking 8 cities in the core city agglomeration of the Chengdu-Chongqing-Guangdong-Hong Kong-Macao axis as the research unit, this paper uses the comprehensive transportation and regional economic development index data of 5 time nodes from 2015 to 2019, combined with the entropy method to comprehensively calculate the weight of each index, by introducing the coupling coordination degree model of the grey relational analysis method to objectively and accurately explores the key indicators that affect the coordination effect of comprehensive transportation and regional economy and the coordination level between cities. The results shows that: the level of coupling coordination between comprehensive transportation and regional economy in cities has been significantly improved, and the level of coupling coordination has developed from a low level to a high level; there are certain differences in the level of coupling coordination among cities. Cities with high levels are concentrated in the Pearl River Delta region and Chengdu-Chongqing region, while cities with weaker coupling coordination are mainly in the northeastern and central regions of South China, which are unbalanced and uncoordinated.
