本研究旨在取用1991年全美釣魚、狩獵及野生動物相關遊憩國家調查資料，分析個人對非消耗性野生動物遊憩活動之支出情形。在選用適切的計量經濟模型過程中，並考量符合消費者需求理論和非消耗性野生動物遊憩活動，複檻式(Double-Hurdle)模型分別應用在分析個人之遠距和近距對非消耗性野生動物遊憩活動之支出情形。實證結果顯示，在遠距支出模型中，個人所得、教育程度、種族膚色、公有林地等影響因子，對於非消耗性野生動物遊憩活動之支出情形具有相對的顯著性。在近距支出模型中，性別、就業狀況、種族膚色、野生動物包括鳥類、哺乳類動物、昆蟲、魚及其他野生動物、前往公有公園或自然地區、維護自然地區等影響因子，對於非消耗性野生動物遊憩活動之支出情形具有相對的顯著性。本研究結果可以瞭解非消耗性野生動物遊憩活動支出之影響因子，藉以提供自然資源經營管理及非消耗性野生動物經營管理在規劃與決策時之參考。

This study utilized cross-sectional data obtained from the 1991 National Survey of Fishing, Hunting, and Wildlife-Associated Recreation to analyze individual's expenditures of nonconsumptive wildlife recreation at a regional level. In the process of selecting an appropriate model most consistent with consumer behavior associated with nonconsumptive wildlife recreation, the double-hurdle model for the nonresidential and residential expenditure models was evaluated. In the nonresidential expenditure model, income, education, ethnicity, public lands, and forestlands had a significant effect on nonconsumptive wildlife recreation expenditures. In the residential expenditure model, gender, employment status, ethnicity, wildlife including birds, mammals, insects, fish, and other wildlife, visiting public parks or natural areas, and maintaining natural areas had a significant effect on nonconsumptive wildlife recreation expenditures. The results in this study provide insight into determinants of nonconsumptive wildlife recreation expenditures which can be used for planning and decision making purposes for natural resource management and nonconsumptive wildlife management.
