Platform-based Innovation：Definition，Mechanism and Suggestions to Challenges
（Jiangxi University of Science and Technology，Ganzhou，Jiangxi341000，China） Abstract：Platform-based innovation is different from organizational independent innovation；it is a collaborative activity of multi subjects based on the space，rules and value network of multi-sided platforms. Platform-based innovation system consists of platform ecosphere，object，subject，and rules，which can provide innovation with basis and breakthrough point to realize the dynamic adjustment and the balance of interests，and promote the inter- attraction of different groups of people and the interdependent of right and responsibility. Platform- based innovation strengthens network value，but not product value；it requires all the members to directly or indirectly complete the innovation，which concerns technological innovation，product innovation，and service innovation. Platform-based innovation takes platform-based value creation as the realization mechanism； the interaction among diversified subjects can produce network effect，which is the binder and innovative catalyzer of cooperation among members. Platform- based innovation will face different kinds of challenges；while building an innovative ecosystem， strengthening services，and cooperatively controlling related risks are the important countermeasures for those challenges.
