Abstract： Based on the theory of system dynamics，the sponge-type prefabricated roads are compared with traditional cast-in-place concrete roads，and the causal relationship diagrams and stock flow diagrams for the incremental cost-effectiveness are constructed of sponge-type prefabricated roads.According to the model simulation analysis based on actual cases，the incremental cost-efectiveness of sponge-type prefabricated roads is studed in detail from three aspects：incremental benefits，incremental costs，and incremental costeffectiveness.Results indicate that the model established efectively supports the comprehensive analysis of the incremental cost-effectiveness of sponge-type prefabricated roads，provides new ideas for evaluating their feasibility and incremental cost-effectiveness，and has a promoting effect on the promotionand application of this type of prefabricated roads.
