Abstract: With the characteristics of innovative industrial clusters summarized, the rich collaborative innovation is proposed as an effective way to promote business innovation in such clusters. As an excellent vehicle for collaborative innovation, the innovation platform can effectively promote business innovation. A superefficient DEASBM (data envelopment analysis and slackbased measure)model with Malmquist index is applied in the empirical analysis. In the innovation efficiency measurement of Guangdong innovative industrial clusters, innovative platform is added to the input variables and output variables are the number of patent applications. The results show that the whole innovation efficiency is high but that there are some differences between the innovation efficiency of different innovative industrial clusters. Innovative platform is an important factor in measuring innovation efficiency. There are large differences between clusters in innovative platform, and the construction of innovative platform is lagging behind in some areas. Five policy recommendations are made based on this conclusion.
