本研究目的在調查台灣民眾經歷過新冠疫情與俄烏戰爭等全球危機後,對於食物浪費的負責任行為是否有所改變,且有哪些因素能夠提升這樣的行為。也希冀藉此調查能填補理論文獻和實務研究的缺口。本研究總共蒐集181位有效填答者資料,並以SEM-PLS進行測量與結構模型的分析與假說驗證。研究結果顯示,全球危機會促使更多民眾減少食物浪費,並提高對食物浪費的道德良知感與責任心,及食物浪費對環境影響的認識。本研究的實務意涵在強調全球危機雖然對於民眾生命財產造成威脅,卻也是提升民眾對食物浪費與環境保護氣候變遷等公民責任感的好時機,藉此提供政府相關單位以全新視角與策略來減少民眾食物浪費之行為。 The aim of this study is to investigate whether the responsible behavior of food waste has changed after Taiwanese people have experienced global crises such as COVID-19 and the Russian-Ukrainian war, and what factors can affect such behavior. It is also hoped to fill the gaps in theoretical literature and practical research.This study collected data from a total of 181 valid respondents. The collected data was analyzed using SEM-PLS to measure and validate the hypotheses within the measurement and structural models. Our findings show that the COVID-19 will lead to more people exhibiting food waste reduction behavior, and increase awareness for the ethics and responsibility for food waste, as well as their awareness of the environmental consequences of food waste. The practical implication of this research highlight that although the global crisis poses a threat to people’s lives and properties, it is also a good moment to raise awareness of food waste for environmental protection and we discuss possible strategies on this matter. Our study offers a new perspective on food waste reduction in the future under the conditions of global crisis.
