Abstract: With the change of regional development environment and structure, the spatial distribution pattern of population and economic around the Yangtze River Delta also presents some changes. This study introduces methods such as geographic concentration, inconsistency index, and imbalance index to compare and analyze the spatial-temporal pattern evolution of geographic concentration and inconsistent index about the population and economic for the Yangtze River Delta during 2000-2015. Meanwhile, the influence factors about their inconsistencies are empirically analyzed based on the panel data regression. The results show that under the pattern of the economic distribution spreading to the regional edge, the population tends to gather to the central region on the whole. Such inconsistence setup between the population and economic is mainly demonstrated by the increase of central regions and the decline of marginal areas, and also by the improvement of the coordination between population and economic spatial layouts. Finally, by the quantitative analyses about the factors to these inconsistencies, it is concluded that the market forces, government policies, urban development status and so on have an important impact on the inconsistence between the population and economic distributions.
