Abstract: The rationality of the population distribution of urban agglomerations is related to the high-quality development of urban agglomerations. Aiming at maximizing the economic benefits of urban agglomerations, this paper deduces the formula for the Structure Rationality Index (E-Zipf) of population distribution. It uses the panel data of 19 major urban agglomerations in China from 2010 to 2020 and adopts the systematic GMM method to calculate E-Zipf. The results show that the E-Zipf index of urban agglomerations in China is 1.33, which is higher than 1. Taking 1.33 as the standard, compared to the traditional standard of 1, the population distribution of 6 urban agglomerations is under-agglomeration rather than over-agglomeration. The results of rational classification show that the population distribution of 6 urban agglomerations, 5 urban agglomerations, and 8 urban agglomerations is reasonable, over-agglomerated, and under-agglomerated, respectively. Over-agglomerated urban areas need to disperse the population of the central city and appropriately develop the peripheral cities, while under-agglomerated areas need to continue to concentrate population in their core cities.
