The state of recycling in Taiwan has seen significant achievements due to various recycling policies implemented by environmental agencies in recent years. These policies include the "Keep Trash Off the Ground" (KTOG) measure, the "Four-in-One Recycling Plan", the per-bag trash collection fee and mandatory garbage sorting. An important question worthy of study is which of these policies has had a more pervasive and critical impact on the outcome of recycling. For example, there is evidence that the KTOG measure made it more convenient for people to begin recycling. This study therefore first analyzed the monthly data over the past decade on the amounts of recyclables in Taiwan's three major cities. By examining time series plots and employing an analysis of the time series intervention model, we can better understand the extent of the effects of the KTOG measure on these cities' amounts of recyclables. The same effects were also analyzed for the mandatory garbage sorting policy and the per-bag trash collection fee. Results show that the KTOG measure, essentially a change in refuse collection practice, presented consistent and significant effects on these cities' amounts of recyclables. It is suggested that the key to improving participation in a recycling program in waste management is for techniques to be tailored to actual settings in a way that facilitates citizen cooperation.
近年来，由于环保机构实施了各种回收政策，台湾的回收利用状况取得了显著成就。这些政策包括“垃圾不落地”措施、“四合一回收计划”、按袋收取垃圾处理费以及强制垃圾分类。一个值得研究的重要问题是，这些政策中哪一项对回收成果产生了更广泛和关键的影响。例如，有证据表明，“垃圾不落地”措施使人们更便于开始回收利用。因此，本研究首先分析了台湾三大城市过去十年中每月的可回收物数量数据。通过检查时间序列图并采用时间序列干预模型分析，我们可以更好地了解“垃圾不落地”措施对这些城市可回收物数量的影响程度。同时也对强制垃圾分类政策和按袋收取垃圾处理费的效果进行了同样的分析。结果表明，“垃圾不落地”措施本质上是垃圾收集方式的改变，对这些城市的可回收物数量产生了持续且显著的影响。建议在废物管理中提高回收计划参与度的关键在于，技术要根据实际情况进行调整，以促进市民的合作。
