The Research on Revaluing the Development of Taiwan in Feng Shang Reservoir in Kaohsiung Abstract Since weekend holidays were carried out, the government has emphasized the tourist recreation and advocated making state-run enterprises with special scenic spots open to the public for promoting use value of their resources. With a trend of economic liberalization, government businesses such as TSC, TPC, and TSIC need operating in diversification and start investing in the tourist industry, each of which is owned based on the government¡¦s initiating plans for increasing the number of tourists. The protective areas of water resource that belong to TWSC are abundant in the ecological environment; however, forbidding people to go there has led to an obvious phenomenon against the unique sources shared by the masses. On one hand, this research, by opening Feng Shang Reservoir in Kaohsiung, can make people closed to water, realize the processing water, understand the importance of water resources to construct a society concerning about water. On the other hand, by using the natural resources there well and multiplying services to attract tourists, it not only has the educational function implied in entertainment but also augments income. But running the protective area of water resources as a tourist site will cause some negative effects of environment and water pollution as well as the anxiety about scaring migratory birds. Therefore, the protection and management of water resources must be under the cautious control. Making use of CVM, this research regards Feng Shang Reservoir as a fictitious market, and the visitors there as research objects of the investigation questionnaire. Besides analyzing the topics like the Development Market Potential, Future Use Benefits, Non-User Benefits¡Ketc, the aims of the research include inspecting the attitudes of customers toward the willingness to participate in and to pay according to the interviewees¡¦ different attitudes of social experiences, different preferences of outside recreations, different identifications of the nature¡Ketc. The results are the followings: 1. Feng Shang Reservoir possesses the market potential. 2. Future use Benefits estimated between $NT30,000,000 and $NT50,000,000 every year are high. 3. Non-User Benefits estimated between $NT160,000,000 and $NT220,000,000 every year are quite high. 4. For the attitudes of customers, labors, government employees, staffs of public school, and people of middle and old age who recognize more about the nature have high willingness to participate in; the common people who recognize less about the nature need to inspire their willingness through educational advocacy. Judging from the above results, this research advises that after appropriately developing Feng Shang Reservoir to the masses, the educational functions of water resources and the social benefits of environment are shared by all the society, which are equal to the return for society and even to TWSC¡¦s positive performance.
