By building the evaluation index system and conducting grey correlation model,the coupling coordinative degree and the driving factors of regional I-U-R innovation system of 31 provinces from 2009 to 2014 were evaluated.The level of industries innovation showed a continued growth trend and held a lead over universities and research institutes.The levels of universities and research institutes innovation were fluctuating upward and slowly increased.The coupling coordination degree of I-U-R innovation system also showed the steady growth,but there is the regional difference.The coupling coordinative degree in east regions was in the state of high level,but the coupling coordinative degree in northeast and west regions were in the state of medium level.The government supporting,the relation intensity of I-U-R,the enterprise'R&D intensity,the enterprise'size,the proportion of state-owned enterprises,the level of regional economy and the level of technology market had a high correlative degree with the coupling coordinative degree but influencing factors had different effects on regions.
