Abstract: The main consideration to design the service model of collaborative innovation service platform for the small and micro enterprises is how to lessen the difficulties in talent, technology, knowledge resource acquisition, and high innovation cost to provide effective services to enhance the technological innovation ability of enterprises. The extension method is used for the matter element model establishment of the manufacturing cluster collaborative innovation platform to construct an extendable service matter element model. To use the extendable matter element model based on the actual needs, the service model can be transformed to improve service functions and contents to solve the incompatible and oppositional problems commonly facing. The extension service model applied to the manufacturing cluster collaborative innovation service platform under the national science and technology support research program is verified technically feasible.
