In this paper, we study the key factors affecting China’s high-speed rail development using a case study methodology and following the perspective of catch-up cycles. In addition to factors such as windows of opportunities and responses identified in the extant literature, we found that the focal organization’s strategic intent is the most important driving force. Strategic intents, opportunities, and responses, all change over time. This finding has important theoretical implications, and indicates the importance of effective coordination by the focal organization in the process of catching up in complex technology systems such as high-speed rail.
