Study on the Influence Mechanism of Food Reserve Behavior of Residents in Metropolis under Major Emergencies:Take Shanghai City as an Example
Major emergencies have a great impact on the food security of metropolitan residents,and the necessary food reserves are an important measure to stabilize the social order.This paper studies the behavioral mechanism of metropolitan residents'food reserves.Taking the theory of planned behavior and the theory of risk perception as the theoretical framework and using the offline research data of 414 residents in Shanghai,this paper empirically analyzes the behavioral mechanism of metropolitan residents'food reserve under major emergencies by means of structural equations.(1)Subjective norms and perceived behavioral control have a greater impact on food reserve intentions than behavioral attitudes,and perceived behavioral control not only directly affects food reserve behaviors,but also indirectly affects food reserve behaviors through the mediating effect of food reserve intentions;(2)information about emergencies positively affects risk perceptions,and food reserve intentions are positively affected by risk perceptions;(3)information about emergencies contributed to the emergence of food storage beliefs,which positively influenced behavioral attitudes,subjective norms,and perceptual-behavioral control,while information about emergencies indirectly influenced behavioral attitudes through the mediating effect of food storage beliefs.The study suggests that measures should be taken to enhance food storage awareness,establish multiple storage channels,and improve information disclosure on emergencies.
