The strengthening of competitiveness and innovation development of SMEs, which account for the majority of Korean companies, cannot be overemphasized. In order to develop the growth of small and medium-sized enterprises and ease polarization between small and medium-sized enterprises, continuous support for R&D personnel, and expansion of education and training, which are good jobs for small and medium-sized enterprises, are important topics in Korea's corporate development policy. Nevertheless, research on education and training for R&D personnel of SMEs has not been activated. Therefore, this study focuses on empirically analyzing the causes of differences in education and training supply by dividing into Group A, which matches the demand and supply of R&D personnel of SMEs, and Group B, which is high in demand but does not support supply. To this end, a binary logistic analysis was conducted to find the cause of the group based on a survey of 761 R&D personnel in the manufacturing sector of SMEs. As a result of the analysis, the education and training matching group was significant in relatively young age groups, low positions, and large companies, while the non-matching group was significant in high age groups, high positions, relatively low degrees, and small companies. Policy implications were presented based on the statistical analysis results.
