As the fourth national level metropolitan area approved in China, the Chengdu metropolitan area is the "core" of the urbanization strategic pattern planning in the main functional area planning of Sichuan Province. One notable feature is not only the integration in economic and industrial fields, but also the concept of ecological and environmental cooperation and governance. Based on the heterogeneity of the economic environment in the Chengdu metropolitan area, this article proposes three governance models: carbon emission ecological compensation, low-carbon technology authorization, and collaborative cooperation. The characteristics and corresponding strategies of different governance models are analyzed, and the application and performance of the three cooperation models are analyzed through case studies. The Chengdu metropolitan area should choose the cooperative governance model that is most conducive to the dual performance of economy and environment based on its own development characteristics and actual situation, in order to achieve the effect of Pareto improvement.
