The industrial sectors can be classified into three sections according to the R&D intensity of industry: high-tech industry, medium-tech industry, and low-tech industry. Despite the importance of low-tech industries in the economy, researchers have given them little attention compared to high-tech industries. Thus, in this paper, I focus on low-tech industries and compare how it differs from high-tech industries. Many studies regarding high-tech industries have focused on the role of R&D intensity on firm innovation. However, this measure may not be appropriate for low-tech industries where innovations in are not usually based on the latest scientific or technological knowledge. Using the data provided by KIS 2008, my findings show that formal R&D activities and university and research institutes' resources have an important role in the innovation of a high-tech industry. On the other hand, in low-tech industry, informal R&D activity, university and research institutes' resources and vertical and competitive resources are shown to be important in innovations.
