Abstract: At present，many big cities in China have enacted financial industry development policies，causing concerns about the overconstruction of financial centersBased on the data of China's financial centers from 2006 to 2019，this paper finds that the current policies promote financial agglomeration in financial centers，which is also the reason for the segmentation of financial marketsIt is because of the market segmentation that forces China's local governments to fall into the “prisoner's dilemma” of policy competitionThe empirical study afterward also shows that the radiation range of national financial centers is much larger than that of regional financial centers，while the radiation effect of national financial centers in west areas and in northeast areas is relatively weakTherefore，optimizing the spatial layout of financial centers has become the effective solution to the “prisoner's dilemma”

Key words: financial agglomeration, financial market segmentation, prisoner's dilemma, spatial layout of financial center
