遊樂園爲觀光產業中非常重要的部分。本研究根據消費者（遊客）對於遊樂園與相關遊樂設施的偏好與需求特性建立理論模型，探討一個提供多種遊樂設施的獨占遊樂園之訂價行爲。研究結果顯示，每一種遊樂設施的最適訂價爲廠商經營遊樂設施的平均成本。該結果隱含了當遊客人數眾多時，遊樂園的最適訂價爲只收取一固定的費用。此外，我們亦發現當遊客對於體驗多種遊樂設施的喜好程度很大時，遊樂園廠商將會服務所有的遊客。本文研究結果可提供相關業者制訂價格決策或政府輔導觀光產業之參考，可視爲個體經濟學訂價理論之應用。

This paper proposes a model to analyze the pricing behavior of a monopolistic amusement park that furnishes a variety of rides. Applying the pricing theory in microeconomics, we examine the optimal pricing strategy of an amusement park based on the observation that customers who are heterogeneous in their preferences for traveling to the park and derive utilities from experiencing many varieties of rides. We find that the park sets the optimal price per ride at the average cost of keeping an amusement facility operating. This implies that charging only a fixed admission fee is optimal when the population of tourists is very large. Further, the park may optimally decide to serve all the potential customers in the market when customers reveal that they are very pleased in experiencing many varieties of rides.
