The government of I-Lan County in Taiwan has assisted in developing tourism for more than 20 years, in holding many festivities, and established I-Lan's branded image to integrate tourism resource. Under these spatial integrated marketing functions, the spatial structure of each important scenic spots becomes that tourists only concentrate in festival spots and festival periods, but less tourist in not festival periods. Changeful spatial structure takes managing risks. For examples, the amount of tourist reduces to only half of the usual in the SARS period of 2003, because of the international folkgame festival was suspended, the whole tourism industry declined. This research believes that managers of I-Lan tourism industries should avoid the habit of relying en the government, and government in I-Lan County should stop creating too many tourism scenic spots with the same property, and should develop public transportation.
