고기술산업과 저기술산업에서 기업의 혁신활동 결정요인 비교 분석

This paper analyzes the determinants of firm's innovative activity, using Korean Innovation Survey (KIS) dataset. Especially, we focused on the difference between high technology industries and low technological industries in performing innovative activities. The product innovation, product improvement, and process innovation are used as proxies for innovative activity. The independent variables such as inter-firm networks, firm size, lagged profit rate, foreign equity ratio, export ratio, firm's age, market concentration ratio, R&D activity and industrial R&D intensity are considered. With data from 1,128 firms for the two years(2000-2001), we estimated the logistic regression model. We found that high-technological-opportunity firms are more innovative than low-technological-opportunity firms not for product improvement or process innovation, but for product innovation. As expected, we also found that there are many differences between high-technological-opportunity firms and low-technological-opportunity firms in both product and process innovation. Another finding is that inter-firm networks have a strong positive effect on firm's innovative activities, regardless innovation type and technological opportunity. Although the inverted-U shape relationship between firm size and innovative activity is presented for process innovation in both high technology industries and low technology industries, the relationship is not accepted within an allowable range of firm size.
