This paper points out the irrationality of the current military airfield runway and its shoulder's width, combining with the reality of the development of airplane, taking into consideration the actual requirements for use, regarding the relationships between airfield construction and local economic development as the starting point. Through calculation and analysis of airplane's demand for runway and its shoulder's width, the suggested rational standards of the runway and its shoulder's width are presented, which both meet the safety in use of airplane and show the remarkable social economic benefits, and also adapt to the development of the airfield.
