This study evaluated the effects of innovation and human capital investments on operating efficiencies of the IC design industry in Taiwan from 2002 to 2004. The data envelopment analysis (DEA) was utilized to measure the efficiencies of IC design companies and the slack variable analysis was used to provide some suggestions about resource distributions for the inefficient companies. The study also used the random-effects Tobit panel regression model to examine the determinants of the operating efficiencies of the IC design industry. The results showed that: (1) the average global technical efficiency for IC design industry was 48.7%, indicating that there were about 51.3% inefficiencies. Most of inefficiencies in operation came from pure technical and scale inefficiencies, and most companies were to lie in increasing returns to scale. The results demonstrated that the operational scales of most IC design companies were too small and the expansions of scales were required; (2) the slack variable analysis appeared that inefficient firms tended to spend too much on innovation capital investment such as research and development (R&D) and human capital investment such as labor costs and employ too many employees and R&D employees for their operations; (3) The random-effects Tobit panel regression results indicated that the important determinants of operating efficiencies for IC design companies included resources each R&D employee owned, employees productivity, number of patents owned, and debit ratio. |
