Abstract

By analyzing data obtained from 301 private R&D projects supported by NEDO, Japan's public management organization promoting private R&D, this study identified the factors that influence the spillover effects of private R&D projects receiving public support. In this analysis, we classified a spillover both within and across firms into "technological spillover," "cognitive spillover" and "social-relations spillover," and explored managerial factors that influence each category of the spillovers. Our analyses illustrated two important dilemmas that a public agency supporting private R&D may encounter. First, we found that while the project starting at the exploratory phase had positive effects on technological spillover, a spillover across firms is restricted when the project is of great strategic importance for a firm. Under the increasing social pressure for the efficient use of public funds, supporting a project with great strategic importance for the firm that committed to its commercialization may be easily justified. However this may prevent the spillover of the project outcome. Second, we found that information exchanges with other internal divisions had positive effects on the spillover both within and across firms. Considering the existing study indicating that heavy dependence on public funds makes the project being isolated within the firm, our analysis may suggest the possibility of a public support by itself hindering spillover effects. These results imply the importance of a supporting agency to deliberately consider the objective of the public support, and to confirm the supported projects not being isolated internally having assistance and cooperation from other divisions within firm.
