%X This paper studies the relationship of network organization and spatia l service system optimization based on analyzing the change of intercity passeng er transport network behind railway's upgrading. The authors choose some indexes , including travel time and the coefficient of temporal location, to evaluate th e benefits of 63 cities, accordingly to the reflection of the optimization and c hange of railway network structure. At the same time, the paper especially studi es eight major transport harbors, including Beijing, Shanghai, Guangzhou, Zhengz hou, Wuhan, Shenyang, Chengdu and Lanzhou. Based on the analysis, we found that: (1) Intercity passenger transport network shows remarkable "time-convergence", an indication of the great optimization of the spatial service system. (2) The i nfluences of optimization's spatial distributions are not equilibrium, the chang e of network structure is not remarkable, but it has the trend of equilibrium. ( 3) Railway's upgrading accelerates the interaction of cities, but the benefits o f eight transport hubs are not the same, either; "500 km half a day of activity circle" has already taken shape, "1000 km a day of activity circle" and metropol itan transport circles such as Beijing and Shanghai are being developed graduall y. (4) After the infrastructure network reaches the "universal" stage, the upgra ding of network organization becomes more and more important to optimize the spa tial service system, accelerate the economic interaction. (5) With the expansion of major hub cities' hinterlands and spatial service scopes, sequentially it wi ll bring strong guidance to relocate economic action.
