Based　on　the　evolutionary　game　theory　and　the　bounded　rational　and　asymmetric　information　assumptions,　we　construct　the　dynamic　evolutionary　game　model　between　the　three　game　players　and　analyze　the　replication　dynamic　equations.　Furthermore,　we　analyze　the　strategy　of　three　symbiosis　units　and　the　evolution　mechanism　of　E-commerce　industrial　park　symbiosis　system.　Finally,　two　conclusions　are　drawn:　Conclusion　1,　the　probability　that　three　symbiosis　units　of　E-commerce　Industrial　Park　choosing　the　symbiosis　strategy　increases　with　increase　of　the　probability　that　the　other　two　symbiosis　units　selecting　the　symbiosis　strategy.　Conclusion　2,　the　probability　of　the　symbiosis　unit　to　choose　the　symbiosis　strategy　increase　with　the　increase　of　the　benefit　and　decrease　with　the　increase　of　the　cost,　risk　and　loss.
