Abstract: To find out the evolution principle of control SME production safety,this article constructed a payment matrix between SME and production safety control agency by the methods of evolutionary economics.Authors disclosed the effect of individuals’choice of policy on group behavior based on analyzing evolution model of interacting process.This paper showed the influence of diversity of decision-making parameters and variation of initial condition on evolution result through reliable numerical simulation.This research found that the evolution of SME' production safety control system converges in two patterns:anideal status and a "locked" status.Through adjusting parameters,the system may jump out of the "locked" status and the supervision of route can be optimized Results implied that SME' production safety control system based on evolutionary economics facilitates to improve the effect of control and guide the microcosmic individual evolving to the expectative direction.

Key words: production safety, supervise, evolutionary game, SME
