Some shows in the past were deemed disappointing by exhibitors and visitors, who complained about poor logistics and exhibits.
Russian aircraft dominated the show's first decade. The situation began to change in 2008 with the appearance of Chinese military parts and the country's C919 jumbo jet and ARJ21 regional jet.
The 150-seat jumbo jet, which is expected to make its maiden flight in 2014 to compete with Boeing and Airbus, won 50 orders at the air show this year, boosting total orders to 380.
The PLA Air Force attended the air show for the first time in 2010 when it displayed aircraft that took part in the 60th National Day parade in 2009, including the H-6 Badger bomber, the JH-7 Flying Leopard fighter-bomber and KJ-200 early warning aircraft.
