Government, enterprises and consumers are the economic subject, the government's power to the economy not only includes the direct participation in the market trading activities shown by the economic power, but also should indirectly interfere with the economic administrative regulation; economic power of the enterprise performance for the elements and The possession of resources and the right to use; consumer economic power through its own endowment resources to influence and control the distribution of labor elements and the choice of consumer goods. The allocation of resources is determined by the power game of each economic subject, and the equilibrium of the game reflects the boundary of economic power. The unequal power of the power of the economy will inevitably lead to a balanced deviation of the power game from the Pareto balance and reduce the total welfare of the society.
