One of the subjects of social science is power. The role of power depends on the capital or resources it holds. There are power paradigms in the field of political science and law research, and the power paradigm is also needed in economic analysis. Political power has the distribution attribute, and the economic power has the production attribute. Interest competition is the driving force of social development, social power (political or economic) structure and interest structure is isomorphic; unequal power structure will lead to the polarization of the structure of interest; only when the power is equal, the power will be transformed. The balance of power game has a variety of forms from cooperative game to prisoner's dilemma; information disclosure is conducive to the improvement of resource allocation efficiency.
