Abstract: In this paper, a multivariate collaboration model of "economy-environment-carbon emissions" is constructed to clarify the coupling relationship between economy, environment and carbon emissions in Shanghai. By selecting the gross economic product(GDP), air pollutant emissions, carbon dioxide emissions and other indicators of Shanghai, a comprehensive evaluation index system was constructed, and the data were processed by using the range standardization method. The coupling coordination degree model is used to calculate the binary and ternary coupling coordination degree between "economy-environment-carbon emissions". The results show that Shanghai has made some progress in the coordinated development of economy, environment and carbon emissions, but still faces challenges, and it is necessary to continue to improve the policy system and promote industrial upgrading and transformation to achieve high-quality coordinated development of economy, environment and carbon emissions.
