This study identifies the factors determining technological innovations in the small firms in Korea. Two groups of 24 innovative and 25 noninnovative small firms are compared on four categories of variables : environmental, strategic, structural, and top management characteristics, which were found to be important determinants of technological innovation in prior research in developed countries. A multiple discriminant analysis reveals that two top managerial characteristics (risk-taking propensity and tolerance for ambiguity), environmental heterogeneity, environmental scanning strategy, and professionalization of organizational structure are the most significant factors discriminating innovative from noninnovative small firms in Korea. The findings suggest that predominant determinants of technological innovation vary according to the types of organization and, in the case of small firms, managerial attitudes toward innovation is the most critical factor. Other strategic and policy implications for the management of innovation in the small firm context are discussed.
