Abstract：With the arrival of "service economy", the service industry is becoming increasingly important in the national economy. Financial is the core of modern economy, the core elements and endogenous variables in economic development. Although many cities are making great efforts to promote financial development, it always seems to appear in the form of agglomeration (eg: financial centers). Financial agglomeration not only has the common characteristics of manufacture agglomeration, but also has uniqueness. The mainly research contents of financial agglomeration include its motivations, modes, types, and effects, the construction of financial center et al. Motivation factors of financial agglomeration can be divided into two aspects of internal and external factors. There are two modes of the formation of financial agglomeration, one is drawing on the path dependence of contingency factors such as history and special events, the other is primarily dependent on the relevant industrial policy of the state, and spatial layout in accordance with the economic development strategy by the government. There have different types of financial agglomeration under different division methods. According to the geographical scope of financial centers, it can be divided into regional-based, national, regional and global type. From the characteristics of spatial layout, it can be divided into the Marshallian new industrial district, the hub-and-spoke, satellite platform, state-anchored district. As the financial agglomeration plays an important role in economic development, how to construct a financial center have become the concerns to many government departments and experts. There are two opposing arguments about the future development of financial services industry: One is that globalization is the synonym of "end of geography", the other is that globalization does not undermine the spatial entity of financial center as a node in the global financial system. Finally, some suggestions are offered for the future research. The first is the research of the functions and industrial layout of China's financial center cities; the second is the sub-sectors and micro-regional research of financial industry.
