The opening of direct flights across the Taiwan Strait: the impact on the global role of Taiwan’s international airport

• Direct flights across the Taiwan Strait increased accessibility from TPE to China.
• Direct flights across the Taiwan Strait did not improve TPE’s hub role.
• Travel regulations of China limit TPE’s development as a hub.
• The competitiveness among airports and airlines limit TPE’s development as a hub.
• Political exclusion of airline use hinders an airport from being a global hub.

Scheduled direct flights between Taiwan and Mainland China were halted for six decades and restarted in December 2008. The Taiwan’s government has a policy of developing Taoyuan International Airport (TPE), the major international airport in Taiwan, as one of main hubs in East Asia, based on the airport’s access to Mainland China. To assess whether the airport is progressing toward meeting the set expectation, this study evaluates the changes in airline networks of the TPE after the opening of direct flights across the Taiwan Strait. The time-dependent earliest arrival time algorithm is applied to global flights in 2004, 2008, and 2012. Empirical evidence demonstrates that providing direct flights across the Taiwan Strait has significantly increased accessibility from TPE to airports in China, but did not improve the centrality of TPE. Additionally, the transfer dependency of TPE on other airports is increasing significantly. This result was based on two major reasons: the first involves the Chinese government’s refusal to allow Chinese citizens to use airports in Taiwan as transfer points to and from other countries and the second reflects the competitiveness among airports and airlines in the region. The key finding is that political exclusion of airline use by external governments via travel regulations adversely influences the development of an airport as a global hub.
