About one third of food are wasted or lost globally every year which causes the problems of environmental degradation, food security issues, and economic inefficiency. With the new mandatory source separation policy implemented in China, the main objective of this research is to identify the variables that impact household food waste reduction intention and to understand the role of perceived government control and perceived policy effectiveness from the perspective of households. Using a PLS-SEM model design, a questionnaire with nine constructs including theory of planned behaviors variables, perceived policy effectiveness, perceived government control, perceived consumer effectiveness, and environmental concern were answered by respondents (n = 3037). Results showed that the less well-studied variables of perceived government control are important in shaping shareholder's food waste intention. As expected, the theory of planned behavior variables, perceived consumer effectiveness, and environmental concern are positively related to reducing food waste intention, while strong perceived government control was associated with lowering intention in food waste reduction. This paper then extends existing understanding of psychological determinants of food waste by identifying perceived government control as mediator.
