The coordinated development level between intensive land use and new urbanization of agglomeration is the core issue in land management. The coordinated development level of middle Yangtze River Region and Chengdu—Chongqing urban agglomeration, which are the urban agglomerations in middle and upper reaches of the Yangtze River, was analyzed to provide some relevant references. Generalization Principal Component Analysis and Mean-Squared Deviation Weight were used to improve the accuracy of the index weight. We used coupling degree model and coordinated development degree model to measure, analyze, compare the coordinated development level of the middle Yangtze River region and Chengdu—Chongqing urban agglomeration. Spatial Autocorrelation Model was used to explore the characteristics and rules of spatial agglomeration of coordinated development level. The results show that the coordinated development level in Chengdu—Chongqing urban agglomeration is close with the middle Yangtze River Region. The coupling coordinated situation in Chengdu—Chongqing urban agglomeration is better than the middle Yangtze River Region. (1) The coordinated development level of the urban agglomerations in middle and upper reaches of the Yangtze River is showing the trend of sustained growth. The coordination degree between the middle Yangtze River Region and Chengdu—Chongqing urban agglomeration is very close in 2013, its value is greater than 0.75 and the coordination development level is in moderate coordination period. Chengdu, Chongqing, Changsha, Wuhan, Nanchang are the areas with high value of coordinated development. Deyang and Huangshi are areas with the low value of coordinated development. The coordinated development levels in other cities are characterized as the medium level. (2) The spatial correlation of coordinated development degree is reduced in the middle Yangtze River Region, transforming from random distribution to weak diversity attribute clustering. The spatial correlation of coordinated development degree is relatively high in Chengdu—Chongqing urban agglomeration, transforming from diversity attribute clustering to random distribution, it will gradually become similar attribute clustering in the future.
