On the view of knowledge, job-related technological achievement is a package composed of explicit knowledge and tacit knowledge, controlled by the R&D department and the inventors respectively. It is not only a significant theoretical issue but also policy issue Whether the inventors can transform the job-related technological achievements. First, this paper puts forward the research hypothesis, the separation between explicit knowledge and tacit knowledge, induces the technology, market, and finance gaps between the transformed body and departments of R&D, consumers, finance arm, respectively; and the bigger the gaps, the stronger that inventors roles. Then, taking the commercialization of DMTO as a case, the paper tests the hypothesis. It finds that it can eliminate the gaps and promote the transformation of job-related technological achievements by means of the spin-off, which means to make inventors and their inventions become an enterprise.
