Independent　innovation　becomes　one　of　the　important　links　to　the　development　of　business　enterprise.　The　effect　of　R　&　D　investment　to　the　enterprise＇s　independent　innovation　is　more　and　more　remarkable.　R　&　D　internationalization　offers　more　favorable　conditions　for　enterprise　with　the　development　of　economic　globalization.　It　also　sets　a　still　higher　demand　at　the　same　time.　We　analyze　the　R　&　D　investment　growth　in　some　countries,　make　an　international　comparison　performed　by　business　enterprise,　and　research　the　evaluation　indicator　system　of　independent　innovation.　Finally,　this　paper　puts　forward　some　suggestions　on　the　improvement　of　enterprise　R　&　D　efficiency.
