This study analyzed the impeding factors faced by venture firms in Daedeok Valley. Initially, the key success factors, including technology level, marketing strategy, network, organization structure, and fund procurement, have been derived from previous literatures. CEOs of 21 venture firms have been surveyed across these key success factors. By carrying out factor analysis, it was found that the general problems faced by venture firms lay in financing, marketing, and networking. In particular, analysis of detailed key success factor indicated that the most critical problems were limited financing opportunities, R&D centered firm strategy, and limited cooperation with research and academic institutes. Based on such findings, policies such as sufficient financing from the government via venture capitals and strong binding of industrial-academic-research complex have been proposed.
