It is recognized that the new technology-oriented companies are important sources of technological innovations and regional development. The purpose of this thesis is to investigate, through exploratory and empirical means, the phenomenon of formation of such companies under Korea``s situation, compared with the cases in advanced countries. Major focus was placed on the characteristics of entrepreneurs, the spin-off pattern, and the relationships between the incubator organization and the new firm. 9 propositions were delineated on the basis of literature review.

The major findings are as follows. First, the technology-oriented companies were started by founders who were in the middle thirties, and did not necessarily have a high formal education. Second, the founders had previous work experiences in the technical areas such as production or engineering department. Such experience operated as a major basis of new company formation.

Academic organizations still did not play such a role. Fifth, the incubator organization determined the initial geographical location of the new firm. Sixth, founders utilized technical skills and knowledge obtained from the incubating companies significantly or decisively in developing their initial products that aimed at different marke...
