Abstract：Research purposes ： Intercity railway network scale measurement is key content of the network planning in urban agglomeration， reasonable network scale can prevent blindness in planning and construction. The cooperative coupling relationship between social economy and the network scale is analyzed and a calculation model is constructed based on a variety of factors. From requirements of planning objectives and structural performance of network two aspects，adaptability of intercity railway network scale is studied. Take Guanzhong urban agglomeration as an example to verify scientificalness and rationality of calculation model. These are valuable for intercity railway network planning in different urban agglomerations. Research conclusions ：( 1 ) The level of socio - economic development of urban agglomeration is a key element that affects intercity railway network scale ; (2 ) The coupling degree between levels of socio - economic development and the size of intercity railway network is related to the development level of urban agglomeration; ( 3 ) From the perspective of network configuration，intercity railway network scale mainly determined by the size of line between key demand nodes; It is necessary to consider the investment constraint and passenger demand restraint in the measurement of intercity railway network scale; ( 5 ) Rationality of network scale embodies in the quantity and quality two levels， balanced coefficient of supply and demand and level equilibrium coefficient are introduced to evaluate; (6 ) The research results can provide theoretical support and decision - making reference for the intercity railway network planning of urban agglomeration , and improve the railway network planning theory system.
