Abstract: The dynamic coupling model of coordinated development of the environment and economy was used to analyze the coordinated development of Kunming from 2010 to 2019. The results showed that the development of environmental economic system of Kunming is in a fluctuating state between low-speed economic development and highly coordinated and balanced development during 2010-2019. The dynamic coupling process showed that there were contradictions between environment and economy,but the evolution speed and relationship of the order parameters of environment and economy could be changed by external conditions,such as the regulation and intervention of economic means and environmental policies and etc. to promote the orderly evolution of environment and economy system.
