Abstract: This paper has studied a method of resource allocation based on system dynamics so that different mobilization means and mobilization preparations can be adopted to satisfy emergency resource demand in different critical states. The process of emergency resource policy’s experimentation and optimization includes: SD model of the release chain of the mobilization potential system is built; mobilization policy rules and parameters are defined; mobilization experiment is carried out and targeted values are determined in the simulation platform. The research shows that whether an economy system can ensure that various states of crisis to emergency resources under the present supply of super-normal ability to meet the mobilization needs depends on whether the reserves and the convertible resource can be released smoothly under the emergency resource mobilization policy，such as emergency resource mobilization preparation and mobilization means of national economy，and whether all kinds of factors of production can show extraordinary ability to supply. Emergency resource preparations and means can strengthen emergency resource mobilization potential，promote releasing emergency resource mobilization potential，deal with all kind of emergency states，and satisfy all kind of emergency resources demand and avoid over-mobilization.
