After that there were JJ merger, JAL's collapse and LCCs-entry on Airline Industry in Japan. Then, this paper estimates the degree of competition and the events' effect on the degree of competition. The result is that JJ merger, JAL's collapse promoted the competition but not all LCCs-entry is promoted the competition. Jet star Japan promoted the competition but Vanila air didn't. Others' entry don't promote the competition significantly.
