초록

Technological innovation is a key driver of firm survival and prosperity in a competitive market. Though most economists consider the determinants of technological innovation as firm-level activities, concentrations of innovative performance within particular regions have been observed almost everywhere. We examine if performance of technological innovation for photonics industry in Korea will be affected by different regions as well as firm specific factors. By applying Heckman’s selection model, we found that specific regions such as Gwangju and Honam region have significant effects on the probability of obtaining patents, but there is no significant evidence that the location on specific regions increases the number of patents. On the contrary, firms with main plants in the SMA have not only significantly lower chances of obtaining patents but also produce significantly fewer patents than do firms in other regions. The analysis also found that the R&D spending–capital ratio, total employment–capital ratio of firms, and firm location in metropolitan cities are all positively related to the number of patents. As a policy implication, more active cooperation between the R&D cluster and the surrounding firms will be required to enhance the technology diffusion effects from the R&D cluster to innovative activity of the firms. This paper contributes relevant literature by showing empirically that regional location is an important determinant of technological innovation for photonics firms.
