According to various countries' high speed rail experience, it is more centralized that the high speed rail of Japanese Shinkansen has brought up Tokyo and two metropolitan population of Osaka, there is difference in the experience of France and Germany, the high speed rail has obviously brought up the population and economy from the outwards scattered phenomenon of metropolis, have promoted the economic recovery of the new developing area. So, the high speed rail in Europe is open to the traffic and obviously promotes the balanced development of area, although become and collect guest's effect angibly, but has not made population concentrate on the metropolis. The excitement of traffic construction is opened up, is it change regional potentiality of structure to have not merely, lead regional strength of driving of development also at the same time, it can shorten space-time effectively from impedance, impel indirectly manpower, the resource one development not positive and utilize, thus have a direct impact on the development-oriented attitudes of the city-region. Divide in the regional respect, the appearance of the high speed rail has expanded the south Taiwanese door chance of stream of people, will change the south Taiwanese location condition too. High speed rail transportation system and appearance of the high speed rail station special zone will bring and have regional impact of three following respects at least, key topic based on this and study. (1)Population and industry are distributed and changes of the economic activity; (2)Change of the regional space structure; (3)Change of the traffic behavior. South Taiwan have one stranger all right a large amount of and new door passed in and out fast, how to attract crowd to stay and consume, it is not the simple traffic transportation problem, depending on the appeal of the area and main development area and gathering serving's ability, these part will challenge the area already existing development will orientate and on sale throughout the tactics inside. Finally, the high speed rail was threatened too already there is commercial scale in KKP Region, to Taipei, the KKP Region relative weak tendency of business environment, if lack appropriate market orientation, the market scale that KKP Region has already had may have been assaulted. This research is observed for the first year studying in three years, expect the economic block evolution to the economic era of Chung-Sun Freeway of economic era of railway from reviews the past, Europe, the external experience of Japan, KKP Region are in the ground characteristic, collected analyzing in the society recently by the ideas of state changing , important enterprises and countermeasure developed of the governments at all levels, develop more concrete influence on the industry and space of KKP Region after visiting the high speed rail and open to the traffic for the first time, planning to make use of more long-term observation to investigate and analyse the regional space of the high speed rail in Taiwan finally influences, regard doing as the government in KKP Region or the central government and grind my humble opinion which proposes the related tactics.
