This paper is based on factor analysis by using SPASS statistical software and establishing Beijing city industrial structure and ecological environment index system. It calculated the coupling degree and coupling coordination degree of the two, to analyze the status of the coupling coordinated development of two systems. The results show that the ecological environment quality in Beijing has improved but is lagging behind and the industrial structure is more reasonable. Besides,economic development does not exceed the carrying capacity of the environment. The two is coupled with stable condition in the high level of coupling stage and the coupling and coordination level increased year by year, and the improvement of the system is obvious. Therefore, we should ensure to upgrade and optimize the industrial structure in the future.At the same time, the emphasis should be placed on improving and protecting the ecological environment.
