External technology acquisition and firm performance: A longitudinal study

External technology acquisition has been viewed as an important method used by firms to achieve higher economic returns. However, only a few studies have evaluated the contribution of external technology acquisition to firm performance. This lack of research is surprising because the benefits of external technology acquisition to innovation output have been emphasized extensively in the literature. This study therefore investigates the extent to which external technology acquisition effects a firm's performance, and how this effect is moderated by internal R&D efforts. This analysis concentrates on the electronics-manufacturing industry, taking advantage of the relative abundance of data on longitudinal investigation variables. A longitudinal sample allows this examination to control extraneous effects and to provide more convincing evidence for the relationship between external technology acquisition and firm performance. The analytical sample comprises a total of 341 Taiwanese electronics-manufacturing firms over the period from 1998 to 2002. The least square dummy variable analysis method reveals that external technology acquisition does not provide a significant contribution to firm performance per se; however, the positive impact of external technology acquisition on firm performance increases with the level of internal R&D efforts. Verifications for robustness and the split-sample analyses both validate the results in the setting of larger firms.
