기술혁신성과에 있어서 R&D협력과 내부R&D투자의 역할에 관한 연구

This study provides an empirical analysis based on 2012 Korea InnovationSurvey (STEPI) to investigate the relation between R&D cooperation and in-house R&Dinvestment. The study further analyzes the effect of the R&D cooperation and in-houseR&D investment on technical innovation. First, the relation between company's in-houseR&D investment and R&D cooperations is estimated with the two equations using SURmodels. Second, the effect of in-house R&D investment and R&D cooperation on thecompany's technical innovation is estimated using Probit model. This study differs fromother existing R&D studies using Korean data in that empirical models are based onstructural relationships among in-house R&D, R&D cooperation, and technical innovation. The results can be summarized as follows; the R&D cooperation expands the in-houseR&D investment and the in-house R&D strengthen the R&D cooperation. Furthermore,In-house R&D investment increases the chances of success in innovation. As we obtainevidence of complementary relation between R&D cooperation and in-house R&Dinvestment, it is necessary to develop environment conducive to this complementarity inorder to have more efficient R&D system.
