In Taiwan, residential businesses is one of the most important supports for the city economy, and that¡¦s why it has gained the reputation of the leader of the industry. Its rises and falls will influence the living quality of the people as well as the general economy of the city. Hence, residential businesses is the key factor for economic rebuilding. The government has adopted various measures to promote ¡§City Vitalization¡¨. However, these policies were invalid due to the change of the industrial types, the migration of the traditional industry, and the increase of the unemployment, which have led to the price drop in real estate. According to the 2002 residential survey, there are 499,429 houses in Kaohsiung with a 16% vacancy rate. In other words, there are 82,275 vacant dwellings. This research was conducted because China and Taiwan have become the members of the World Trade Organization¡]WTO¡^ in 2001 and 2002 respectively, which would substantially liberalize the so-called ¡§three-links¡¨ policy. In practice, it will increase the international trade opportunities for both sides of Taiwan Straits. Direct flights are a virtual certainty. The negotiations on air ties will set a brand-new situation. When it comes to direct flights, Taiwan government holds ¡§Kaohsiung is before Taipei¡¨ policy. Therefore, The Kaohsiung International Airport will be the top priority. Consequently magnificent commercial opportunities will be brought and undoubtedly benefit the residential property. Nominal Group Technique¡]NGT¡^ is a way of organizing a meeting to enhance its productivity. Its purpose is to balance and increase participation, to use different processes for different phrase of creative problems solving and to reduce errors in aggregating individual judgments into group decisions. It is especially useful for problem identification, problem-solving and program planning. For gathering various opinions, researchers have attended NGT meetings twice, conducted a questionnaire, and interviewed experts and the conclusions are described as follows:Kaohsiung, located in the southern part of Taiwan, is not only the biggest commercial harbor and the second largest city in Taiwan, but also the chief center of the heavy industry. If the government could improve its image and investment environment to attract foreign businessmen and capital, its real estate would boom again. As the reason mentioned above, Kaohsiung government should actively participate in talks on the issue of ¡§three links¡¨ and request Beijing to put forth concrete strategies to promote collaboration between both sides of the Taiwan Straits for a win-win relationship.
