Data_Sheet_1_The effect of COVID-19 risk perception on pro-environmental behavior of Chinese consumers: Perspectives from affective event theory.docx

IntroductionCOVID-19 has altered human cognition and changed the cultural values of society. However, there has not been much debate among scholars about whether these above changes have led to an increase in pro-environmental behavior (PEB) of Chinese consumers.
MethodsA comprehensive model was developed based on affective event theory. An online questionnaire was distributed, and 501 usable questionnaires were collected. In addition, two complementary approaches were employed: partial least squares structural equation modeling (PLS-SEM) and necessary condition analysis (NCA).
ResultsThe PLS-SEM results showed that COVID-19 risk perception, nostalgia, the awe of nature, and attitude were found to have a positive effect on PEB; and the moderating effect of power distance belief (PD) between nostalgia (NO), attitude (AT) and PEB was confirmed. According to the NCA results, AT and NO are necessary conditions for the PEB of consumers.
DiscussionThis study provides deeper insight into the understanding of consumers’ pro-environmental behavior in the context of COVID-19 through the combined use of PLS-SEM and NCA.

引言：新冠病毒（COVID-19）改变了人类的认知，重塑了社会的文化价值观。然而，学界尚未针对此类变革是否推动中国消费者的亲环境行为（pro-environmental behavior, PEB）增长展开充分探讨。
方法：本研究基于情感事件理论构建了综合研究模型。通过线上问卷发放回收，最终获得有效问卷501份。此外，本研究采用两种互补分析方法：偏最小二乘结构方程模型（partial least squares structural equation modeling, PLS-SEM）与必要条件分析（necessary condition analysis, NCA）。
结果：偏最小二乘结构方程模型（PLS-SEM）分析结果显示，新冠疫情风险感知、怀旧、自然敬畏感以及态度对亲环境行为具有显著正向影响；同时证实了权力距离信念（power distance belief, PD）在怀旧（nostalgia, NO）、态度（attitude, AT）与亲环境行为之间的调节效应。必要条件分析（NCA）结果表明，态度与怀旧是消费者亲环境行为的必要条件。
讨论：本研究结合偏最小二乘结构方程模型与必要条件分析，深化了对新冠疫情背景下消费者亲环境行为的认知与理解。
