Technological Difficulty, Technological Spillover, and Private Incentive for Cooperative R&D

기술개발의 난이도와 기술적 파급효과가 기업의 공동연구개발 선호에 미치는 영향 -비용분담형 공동연구개발과 연구배증형 공동연구개발간 기업의 선호조건 비교-

Firms prefer in some specific conditions cooperative R&D to non-cooperative for developing technology. Previous studies on the conditions show firms want to choose cost-sharing type of cooperative R&D (the CS-RJV) rather than non-cooperative one when target technology is either 'relatively easy'or 'relatively difficult', and to join multiple-research type of cooperation (the MR-RJV) than to compete each other if technology is only 'relatively easy'. However, by introducing technological spillover as well as difficult of technology, only if there shown that this seemingly contrasted phenomenon almost disappears : the MR-RJV can i3e also preferred by firms even in case of 'relatively difficult'technology only if there exists some extent of a technological spillover.
