Abstract: The feedback effect of rate is an important part of building the accident prevention mechanism of Occupational Injury Insurance based on risk evaluation. The feedback warning mechanism of the enterprise occupational injury insurance based on risk evaluation is studied by using the theory of safety control engineering, and this paper also put forward that the feedback effect of rate not only lies in basic feedback--economic leverage, but also has risk early warning on the enterprise safety management. At last, the practical function and realizing condition of the risk early warning feedback is discussed.
