【Abstract】From the perspective of population scale, spatial scale and economic scale, an evaluation model of urban size distribution rationality in urban agglomeration is constructed based on fractal theory. This paper explores the characteristics of urban size distribution and rational evolution of 19 urban agglomerations in China. The results show as follows: (1) The urban scale distribution of China’s 19 urban agglomerations is mostly concentrated ones, and the imbalance of urban scale distribution will continue. (2) Most of the eastern coastal urban agglomeration is in a high-reasonable stage or a high-reasonable and moderately interactive fluctuation stage. The rationality index of the urban agglomerations in the central and western regions changes greatly, and some urban agglomerations enter the stage of high-reasonable urban scale distribution. (3) Urban size distribution in urban agglomerations can be divided into three types: superior scale distribution, fluctuant scale distribution, and inferior scale distribution. (4) The evolution path of urban size distribution in urban agglomerations is a large “S” shape evolution curve composed of multiple “S” shape curves, which can be divided into four processes: unreasonable stage, low-reasonable stage, moderately reasonable stage and high-reasonable stage.
