Yet external competitive environment changes, railway corporation organization evolution and internal resource readjustment are primal to corporate sustainable development and competitively increases. 　　In past decades, Taiwan Railway Administration (TRA) played an important role in intercity transportation and regional transportation. With the entry of high-speed rail into intercity transportation market, TRA seems to have the need to readjust its management operation strategy. Though TRA’s current operation performance lacks satisfaction, TRA still possesses many potential operational competitive advantages including large volume of land property, specialized railway human resources and abundant fixed cash income. 　　Therefore, this study will adopt economies of scale and economies of scope theories to analyze TRA’s input and output efficiencies through Translog cost function. Thought previous railway cost analysis focus mostly on already available historical data, this study would like to include forecasts on TRA’s operational input and output evolutions after the entry of high-speed rail. This study aims at analyzing TRA’s possible market positioning and most suitable resource distribution after the high-speed rail era. 　　The study finds：Firstly, both of TRA’s operation have specific and integer economies of density and economies of scale. Second, the track’s operation has integer economies of scope, except middle and long distance passenger transport don’t have pair economies of scope, Both of freight transport and middle and long distance passenger transport and freight transport and short distance passenger transport have pair economies of scope. The subsidiary operation don’t have economies of scope. Third, all input factors of track operation are substitutes. The material and middle-input are complementary in subsidiary operation, others are substitute. The input factors of two items of business accord with the demand rule. Fourth, the track operation is technological progress, the subsidiary operation declines for technology. Fifth, the short distance passenger transport fixed price of the track business is on the low side, the middle and long distance passenger transport should fix the price flexibly. Finally, under the impact of high-speed railway, TRA has economies of scale but don’t have economies of scope.
