摘要

本研究探討水田在景觀、遊憩、文化、藝術、教育等方面可能產生之使用價值與非使用價值，採用非市場財價值評估法中的旅遊成本與條件評估法，評估水田多功能之價值。在使用價值方面，本研究調查93年7月至94年6月一年間曾從事水田多功能體驗者之支出情形，由遊客支出估計水田作為遊憩體驗使用的貨幣收益約為83.47億元。在遊憩效益方面，以旅遊成本估計之遊憩效益為29.29億元。而在非使用價值方面，應用條件評估法，推估之總非使用價值為66.19億元。另由農業統計年報得知2004年水之生產價值為275.11億元，再加上文獻中評估之生態功能價值為1,301.57億元，因此估計水田的總價值為1,755.63億元。由以上結果得知水田各項價值中，生態價值佔74.14％，生產價值佔15.67％，體驗支出、遊憩價值與非使用價值則佔10.19％。若僅討論水田之生產、體驗支出、遊憩及非使用價值，則生產價值佔60.59％，但體驗支出亦佔了18.38％，而遊憩效益及非使用價值也分別佔了6.45％及14.58％，因此水田的真正價值並不能僅以生產價值來表示之。

This study surveyed the possible use and nonuse values of rice paddy on scenery, recreation, culture, art, and education aspects. Travel cost method and contingent valuation method were applied in this research to evaluate the multi-function value of rice paddy.The total monetary expenditure estimated by expenditure regression from tourists with experiences on the multi-function of rice paddy in the pertiod during July 2004 and June 2005 was NT$ 8,347 million. The recreation value estimated by travel cost method was NT$ 2, 929 million. The nonuse value estimated by contingent valuation method was NT$6,619 million. According to the Yearly Report of Taiwan Agriculture and related references, the production value of rice in 2004 and the ecologic value of rice paddy were NT$ 27,511 million and estimated NT$ 130,157million, respectively. Therefore, the total value of rice paddy was estimated NT$ 175,563 million. Results indicated that ecological value, production value, and other (experience expenditure, recreation, and nonuse) value comprised the total value of rice paddy with shares of 74.14%, 15.67%, and 10.19%. When the ecological value was disregarded, the production value, the experience expenditure, the recreation value, and the nonuse value comprised 60.59%, 18.38%, 6.45%, and 14.58% of the value of rice paddy. It revealed that the true value of rice paddy could not simly be represented by the production value alone.
