中文摘要 | 維持原始風貌的濕地利用方式可為社會大眾帶來許多正面的外部效果,但是這些外部效益在以往濕地利用決策過程中往往被忽略,因此常導致高估濕地開發價值與低估保育價值的現象。為了解與辟免忽略外部效果導致濕地資源錯置的情況,本文利用靜態與動態經濟模式分析濕地有效利用(納入外部效果)的課題,結果顯示未能將開發環境機會成本納入考量時,將導致濕地過度轉用的情況。為了修正此種「市場失靈」與避免走向「全有或全無」的發展模式,濕地保育評價將扮演一個相當重要的角色。 |
英文摘要 | Wetlands in their natural state provide many beneficial externalities for society. In the past, wetlands use policy decision process have generally failed to incorporate these social benefits into the analysis. This will lead to an overestimation of development values and underestimation of preservation values. This paper use an economic approach to debate and discussion on wetlands beneficial economic use issues. The analysis of an economic model indicates that failure to consider the environmental opportunity cost of wetlands loss will lead to excessive wetlands are converted to alternative uses. In order to correct the "market failure" and avoid "all or nothing" use pattern, wetlands conservation valuation will play an important role. |
