Time-series network analysis of civil aviation in Japan,1985-2005
Due to the airline deregulation in 1985,a series of new airport developments in the 1990s and 2000s,and the reorganization of airline companies in the 2000s,Japans air passenger transportation has been dramatically altered in the last two decades in many ways.In this paper,the authors examine how the network and flow structures of domestic air passenger transportation in Japan have geographically changed since 1985.For this purpose,passenger flow data in 1985,1995,and 2005 were extracted from the Air Transportation Statistical Survey conducted by the Ministry of Land,Infrastructure and Transport,Japan.First,national and regional hub airports are identified via dominant flow and hub function analysis.Then the roles of the hub airports and individual connections over the network are examined with respect to their spatial and network autocorrelations.Spatial and network autocorrelations were evaluated both globally and locally using Morans I and LISA statistics.The passenger flow data were first examined as a whole and then divided into 3 airline-based categories.Dominant flow and hub function enabled us to detect the hub airports.Structural processes of the hub-and-spoke network were confirmed in each airline through spatial autocorrelation analysis.Network autocorrelation analysis showed that all airlines ingeniously optimized their networks by connecting their routes with large numbers of passengers to other routes with large numbers of passengers,and routes with small numbers of passengers to other routes with small numbers of passengers.The effects of political events and the changes in the strategies of each airline on the whole networks were strongly reflected in the results of this study.
