To answer the questions above mentioned this research utilizes an experimental design and analyzes how discount levels expiration activation of unused amounts and unused amounts affect intention of prepaying product purchase intention and restoring intention Important results are discovered as followed (1)Higher discounts are significantly correlated to higher intention of prepayment; however they do not react significantly to the product purchase and restoring intention (2)Expiration reduces the intention of prepaying but increases product intention (3)The effect of activating unused amounts on intention of prepaying and product purchase intention is not significant and the moderating effect of unused amounts on restore intention isn't significant (4)The moderating effect of discounts and unused amounts on restoring intention is significant The practical suggestions offered by this research are:(1) Remind customers how they use what they already buy (2) Activating unused amounts can increase not only product purchase intention but restoring intention (3) Even when expired companies should also allow customers to activate unused amounts (4) Provide special discounts to those who leave higher unused amounts

为了探讨上述问题，本研究利用实验设计的电脑情境模拟，探讨不同形式的预付方案对消费者购买方案、购买产品及储值意愿之影响。本研究所得之重要结论为：(1)折扣幅度越高则消费者购买预付方案之意愿越高，但对购买产品及储值的影响却无显著的差异。(2)有使用期限会降低消费者购买预付方案的意愿，但却提高购买产品之意愿。(3)残值可否续用对购买方案及购买产品意愿的影响并不显著，且与高低残值对储值意愿的交互作用也不显著。(4)折扣幅度与高低残值的交互作用对储值意愿的影响是显著的。本研究之实务建议为：(1)提醒顾客已购买方案的使用情况。(2)采用残值可续用方案不仅可促进购买方案意愿，还可增加储值意愿。(3)到期后，仍提供残值可续用方案给有余额的消费者。(4)针对余额高的消费者，额外给予储值的价格优惠。
