Technology transfer (or sharing) is a common way to share external sources. There have been many studies on the relationship of self-R&D and technology transfer regarding its theoretical background and its efficiency. This present research has been developed by examining how a concrete measure of a company or a firm's real performance (increased sales ratio; growth rate) is related to the variables of resources and capabilities using the resource-based theory and open innovation model. The approach of this research is unique in that it examines a sample comprising of licensing-in and technological cooperation variables, categorizes forms according to industry, and looks at such unique variables as a "process" (the ratio of CEO's and related-person's stocks). The data on 361 Korean firms was gathered from Korea's Data Analysis, Retrieval, and Transfer System and Worldwide Intellectual Property Search. Findings show that human, technology, and fixed assets are related positively to financial performance, and searching, absorbing, and openness capabilities as a control effect is related positively to a firm's increased sales ratio. Strategic plans for technology transfer companies are also included in this research.
