文摘For the problem of price fluctuation in the commodity market, some ordinary differential equation models are proposed and the stability of equilibrium price is studied. In this paper, we develop a mathematic model for price cooperation with diffusion and lag. When the economic parameters satisfy some conditions, the existence and stability of periodic price are investigated.
