説明

The aim of this paper is to explain how an established firm can sustain its competitive advantage against a radical technological change. We focus on the transferability of resources already accumulated in another division to the division that faces a radical technological change, especially manufacturing technology transfer. In this paper, we look into the process of technological change in the printer business of Seiko-Epson. The printer industry had faced a radical technological change, from dot matrix to inkjet. Many firms that had competitive power in the dot matrix market lost its power by this radical change. However, Seiko-Epson succeeded in changing its technology from dot matrix to inkjet, and sustains its competitive advantage. Why could Seiko-Epson succeed in changing its technology? We found that Seiko-Epson transferred the fine pressing technology accumulated in the watch division to the printer division when they developed inkjet printer. This technology transfer played three important roles. Firstly, it becomes a detour investment, and facilitates the investment in the alternative technology, inkjet. While many firms failed to invest in the brand-new alternative technology, Seiko-Epson did not suffer from this problem, as the fine pressing technology was the existing resources that already been accumulated in the watch division. Secondly, it contributes to the quality improvement of inkjet printer, especially the printing accuracy. And thirdly, it contributes to the construction of a competitive advantage, because manufacturing technology like fine pressing is so ambiguous that other firms cannot imitate easily. Finally, we suggest that the transferability of resources from another division to the division that faces a radical technological change is an important aspect of innovation research.
