Industrial　clusters　are　widely　considered　as　the　most　remarkably　successful　developing　mode　of　regional　economy.　Though,　the　present　literature　and　conclusions　on　its　evolution　are　rather　confusing.　This　paper　re　views　the　current　literature　on　industrial　clusters　from　perspectives　of　bottom-up　approaches,　in　an　attempt　to　revealing　the　micro-foundations　that　underpin　their　evolution.　By　swarm-simulation　approach,　which　is　introduced　as　an　effective　approach　to　describe　and　experiment　evolution　of　an　industrial　cluster,　this　paper　argues　that　firms＇　adaptive　behaviors　are　one　of　the　driving　forces　which　push　the　evolution　of　industrial　clusters.　The　paper　concludes　that　geographical　proximity,　social　behavior　coordination　mechanism　and　government　intervention　are　prerequisites　for　industrial　clusters＇　evolution.　©　2011　IEEE.
