The Driving Factors of Food Waste in Chinese Urban Households: A Qualitative Study Based on Grounded Theory

Abstract

Food waste has become an increasingly common and serious global problem, affecting the guarantee of food security in China and the sustainable development of the national agricultural and food system. Urban households are the main source of food waste on the consumer side. Given China’s unique culture, economy, and social environment, the drivers of food waste in urban households need to consider broader social, psychological, and situational factors in order to provide a basis for formulating and implementing targeted policy measures. This article conducts a grounded theoretical analysis of semi-structured interview data from 56 urban households in China and constructs a driving factor model for food waste in urban households in the Chinese context. Research has found that the influencing factor system of food waste in Chinese urban households includes seven interrelated main categories. Among them, risk perception has a direct effect on responsibility awareness and behavioral tendencies, responsibility awareness and environmental pressure have a direct effect on behavioral tendencies, behavioral tendencies have a direct effect on behavioral choices, perception barriers play a moderating role in the impact of risk perception on responsibility awareness and behavioral tendencies, and behavioral constraints play a moderating role in the impact of behavioral tendencies on behavioral choices. This study enriches the research on the mechanism of food waste behavior in Chinese households, providing scientific basis for the formulation of intervention strategies for food waste in Chinese households, and also providing reference for revealing the mechanism of food waste behavior in other countries with similar cultural backgrounds.
