By　swarm-simulation　approach,　this　paper　argues　that　firms＇　adaptive　behaviors　are　one　of　the　driving　forces　pushing　the　evolution　of　industrial　clusters.　The　growth　of　industrial　clusters　thus　depends　heavily　on　the　interactions　between　firms　inside　clusters,　in　perspective　of　multi-agents　games.　The　conclusions　that　the　factors　including　geographical　proximity,　social　behavior　coordination　mechanism　and　government　intervention　are　prerequisite　conditions　for　industrial　clusters＇　growth　are　drawn　through　the　analysis　of　the　results　by　simulations　based　on　java-swarm　platform.　Some　suggestions　are　proposed　accordingly.
