Producers,　suppliers　and　customers　in　an　industrial　cluster　have　close　relationships.　The　exchanges　including　multi-purchase,　multi-manufacture　and　multi-distribution　are　frequent.　Therefore　these　exchanges　initiate　massive　demands　of　informatization.　But　the　life　cycle　theory　of　industrial　cluster　indicates　that　there　are　different　characteristics　in　different　cluster＇s　lifecycle　stages.　According　to　analyzing　the　characteristics　of　each　life　cycle　stage,　the　paper　puts　forward　how　to　adopt　informatization　strategies　in　different　steps,　in　order　to　achieve　the　goals　of　cultivating　and　maintaining　cluster＇s　competitive　advantages　and　extending　cluster　lifecycle.
