The　system　of　collaborative　competition　shows　swarm　intelligence　features　through　individual　co-interactive.　Based　on　the　predominance　of　Multi-Agents　Simulation　in　describing　and　modeling　a　complex　system,　a　model　of　the　enterprise　collaborative　competition　was　built.　The　model　defined　every　enterprise　as　an　agent　and　defined　agent　actions　combining　Holland＇s　ECHO　model.　In　the　model,　the　mechanism　of　behaviors　and　simulation　parameters　were　designed.　The　dynamic　competitive　behavior　of　the　enterprises　was　simulated　through　java　language.　Finally　the　results　of　the　simulation　were　analyzed.
