“…Because we did not have the data on R&D expenditures of firms in the sample, SIC codes were used to identify the high technology firms in this study. Based on the literature (Bruton & Wan, 1994;Harpaz & Meshoulam, 1997;Hoyt & Matuszek, 2001;Lee & Shim, 1995;Liao & Cheung, 2002;Lynn, Schnaars, & Skov, 1999;Maryland Career & Workforce Information, 2002;McGee & Dowling, 1995;PriceWaterhouseCoopers, 2000;Rausch, 1998;Smith & Zahrly, 1993;The Chemical Industry, 2002;Wang, Lee, & Huang, 2003;Watanabe, Kishioka, & Nagamatsu, 2004;Wilbon, 2002), the following SIC codes emerged as industries in which high technology firms operate: 28, 346, 35, 36, 37, 38 (see Table 2 for the definition of industries). Thus, the firms with these SIC codes comprised the sample of high technology firms; the firms with other SIC codes in the sample were eliminated.…”
