This　paper　presents　a　study　of　the　behavior　in　firms　receiving　the　government＇s　policy　support.　It　is　emphasized　that　firm＇s　attitude　is　an　important　factor　to　policy　planning.　Resource-based　theory　is　also　adapted　to　firm＇s　response　to　the　innovation　policy　of　industrial　cluster.　In　the　perspective　of　complex　adaptive　system,　policy　responding　has　suffered　from　the　influence　of　some　factors　such　as　comprehension,　firm＇s　scale,　entrepreneur,　benefit,　innovative　capability,　demands　for　R&D　and　neighbor　firms.　Based　on　echo　model,　the　paper　discusses　the　mechanism　of　cluster　firm＇s　response　to　innovation　policy.　Furthermore,　it　describes　the　important　role　of　various　factors　play　in　the　process　of　policy　responding　and　trigger　condition.　Finally,　the　behavior　matching　modes　and　self　-　adaptive　responding　flow　have　been　analyzed.　Findings　show　that　the　fundamental　of　firm＇s　response　to　policy　is　resource　-　depending　and　self　-　organizing　evolution　ensures　policy　responding　better　and　better.　©　2013　Springer-Verlag　Berlin　Heidelberg.
