Comparisons of technological innovation capabilities in the solar photovoltaic industries of Taiwan, China, and Korea

Abstract

This paper investigates the technological innovation capabilities of the three Asian latecomers--namely Taiwan, China, and Korea--in the emergent solar photovoltaic industry. For this study, I deploy a new dataset of 75,540 solar photovoltaic patents taken out by Taiwan, China and Korea over the period of 31 years (1978---2008) and analyse the evolving technological innovation capabilities revealed in these patents using a set of four technology platforms that I constructed. This study demonstrates the patent portfolios of the three latecomers and explores what extent have the Taiwanese, Chinese, and Korean followers developed their technological innovation capabilities so as to surpass the US, German, and Japan and acquire the leading production positions; and how the variations of technological innovation capabilities among the major producers influence their business activities in the global solar photovoltaic industry. The results show the various strategies adopted by Taiwan, China, and Korea to develop their solar photovoltaic industries, reflect their different national innovation systems involved, and response to the current trends of technology development in the global solar photovoltaic industry.
