Measuring the relative efficiency of IC design firms using the directional distance function and a meta-frontier approach
Abstract: This paper presents an alternative approach for evaluating the efficiency of integrated circuit (IC) designfirms. In doing so, it accounts for differences between technology groups containing one or more designfirms, and input and output factors to prevent influences of scale (e.g., firm size). Specifically, we employeda directional distance function approach to data envelopment analysis in order to evaluate inefficiency scoresand differences among groups based on input and output factors. We found the efficiency of Taiwan's ICdesign firms to be dependent not only on firm size but also on R&D expenditure and patent revenue. Ourfindings suggest that these factors significantly influence the technical efficiency of Taiwan IC design.Furthermore, by focusing on technology gaps, we offer some suggestions for the different groups based ongroup-frontier and meta-frontier analyses. Finally, using the results of these analyses, we extend the globalresults of this study, presenting ways to further improve efficiency.
