In the course of human social development, with the emergence of new technologies, new things, and new business forms, the drivers of economic growth, the composition of social strata, and the resource allocation demands continue to change, and new interest demands and even new interest groups are constantly emerging. At such times, the original political governance system and economic institutions may become incompatible with economic and social development. Only by promptly adjusting the political governance and economic institutions in line with the needs of economic and social development can a country ensure high levels of economic accessibility and political cohesion. Taking financial technology (fintech) as an example, this chapter explores the institutional reasons behind its rapid development in China and its role in enhancing China’s economic accessibility and political cohesion. On this basis, it also discusses how to respond to emerging entities to maintain high economic accessibility and political governance cohesion.
