By constructing the environmental and economic development model, this paper analyzed the coordinated degree on environment and the economy in 31 provinces of China. The results showed that, the differences on economy and environment are great in various regions. From the economic development level, we could see that the eastern regions were the best, the central were the better and the west were the worst. From the environment development level, we could see that the western region is the best, the east is better, and the middle is the worst. From the coordinated degree of environment and economy, the eastern region obviously were higher than that in the midwest, and the economy and environment in eastern regions formed the benign coordinated development, but the midwest fails to form a positive development situation.
