基于TAM和感知风险的城市居民再生水回用行为影响因素研究

Research on Influencing Factors of Recycled Water Reuse Behavior of Urban Residents Based on TAM and Perceived Risk

快速的城市化进程和社会经济发展造成了水资源紧缺和水环境污染,再生水作为一种重要的替代水资源无疑是解决该问题的有效途径。文章将技术接受模型(TAM)和感知风险理论引入再生水回用行为研究领域,建立城市居民再生水回用行为影响因素的理论模型,并提出相应的研究假设。利用问卷收集数据,并对523份有效样本数据的信度与效度进行了验证,在此基础上,采用结构方程对理论模型进行了实证检验。结果表明:(1)感知易用性和感知有用性会影响公众的再生水回用行为态度;(2)公众对再生水的潜在风险意识会显著负向影响其再生水回用行为态度;(3)公众的再生水回用行为态度能显著影响其行为意愿,且还是感知易用性、感知有用性、感知风险作用于行为意愿的中介变量。

The rapid urbanization process and socio-economic development have caused water resource shortage and water environment pollution.As an important alternative to water resources,recycled water is undoubtedly an effective way to solve this problem.This study introduced technology acceptance model(TAM)and perceived risk theory into the research field of recycled water reuse behavior establishes theoretical models of influencing factors of urban residents’recycled water reuse behavior,and proposes corresponding hypotheses.The questionnaire was used to collect data,and the reliability and validity of 523valid sample data were verified.On this basis,the structural equation model was used to test the theoretical model.The results show that:(1)perceived ease of use and perceived usefulness will affect the public’s attitude towards recycled water reuse behavior;(2)the public’s awareness of the potential risk of recycled water will significantly negatively affect its recycled water reuse behavior attitude;(3)the public’s recycled water reuse behavior attitudes can significantly affect their willingness to act,and are important mediators of perceived ease of use,perceived usefulness,and perceived risk indirect effects.
