سنجش باز بودن سیاست بین المللی حمل و نقل هوایی چینی

Based on the Standard Air Liberalization Index, developed by WTO in 2006, an improved indexing system is constructed with a new indicator of grant of O&D points, along with improvement of the variants for the indicators of grant of freedom rights, capacity, and withholding, as well as the adjustment of scores for some variants. All of China's original bilateral air service agreements (ASAs), and their amendments, by June 2016, are collected and first analyzed descriptively. The quantitative measurement results show that liberalization of China's ASAs is gradual, which is in agreement with the conclusions from the descriptive analysis. China's international air transportation has been liberalized progressively and significantly after 1992, and its degree of openness in June 2016 was three times that in 2000. Hitherto, there has been no long time series and comprehensive quantitative measurement on the liberalization of a country's international air transport policy, especially covering all ASAs and their amendments, which could help understand the development of China's policy. Furthermore, the results could form an essential dataset for further research on the impacts of liberalization of international air transportation.
