［Purposes］ In order to promote the development of new urbanization and the adjustment of economic structure in Chongqing, to reveal the coupling coordination law between economy, urbanization and carbon emissions. ［Methods］ Taking 38 districts and counties in Chongqing as a unit, the evaluation index system of economy-urbanization-carbon emission subsystem was established, and the coupling coordination model was constructed to analyze the spatial variation and evolution characteristics of subsystem coupling coordination in 2015, 2017 and 2019. ［Findings］ The results showed that: 1) The spatial distribution of coupling coordination was greatly affected by the comprehensive development level of districts and counties. Among the counties with high level coupling coordination, 60% were in metropolitan areas, and only 16% were in southeast Chongqing. 2) The coupling coordination changes have convergent correspondence characteristics. In the metropolitan area, double high level coupling coordination is 93%, while in northeast and southeast Chongqing, double low level coupling coordination is 52% and 33%, respectively. 3) There are significant differences in coupling coordination degree. Spatially, the coupling coordination degree presents a “point + line” structure, with the urban functional core area, Wanzhou in northeast Chongqing and Qianjiang in southeast Chongqing as the central radiating points, forming a gradient line with high east and low west. In time, the coupling degree is an “inverse L-shaped” rising curve, and the coordination degree is an “M-shaped” wave curve. ［Conclusions］ Due to the differences in economic and urbanization development levels between regions and counties, carbon emission reduction policies should be tailored to local conditions, and different policies should be implemented in the aspects of industrial coordination, urban and rural overall planning, and increasing income and reducing expenditure.
