基于结构方程模型的再生水回用公众接受程度研究

Research on public acceptance of reclaimed water reuse based on structural equation model

摘要:

再生水回用公众接受程度是影响其推广的关键因素,因此,对再生水回用公众接受程度进行研究至关重要。以西安市公众为例开展问卷调查,构建了公众接受程度影响机制的假设模型,运用AM0S21.0软件对获得的584份有效样本数据和假设模型进行结构方程模型的拟合检验,并分析不同群组公众的结构方程模型拟合参数的特点。研究结果表明：再生水回用公众风险感知(β=0.213)、主观规范(β=0.271)和感知行为控制(β=0.379)通过回用态度间接影响接受程度,态度直接影响公众接受程度(β=0.699),最后从立法、监督、宣传三个方面提出了进一步促进城市再生水回用的建议。

Abstract:

The public acceptance of reclaimed water reuse is a key factor to influence the promotion of reclaimed water,therefore, it is importantly to study it. The research,taking the public of Xi"an as an example to carry out the questionnaire survey, constructs a hypothetical model of the public acceptance mechanism, does a structural equation model fitting inspection between the obtained 584 effective sample data and the hypothesis model by AM0S21.0 software,and analyzes the characteristics of structural equation model fitting parameters in different public groups. The results show that the public risk perception (β= 0.213), subjective norms (β= 0.271) and perceived behavioral control (β= 0.379) indirectly affect the degree of acceptance through the attitude , while the attitude directly affects the public acceptance (β= 0.699). At last,three suggestions which are legislation, supervision and publicity have been puts out to promote the urban reclaimed water .
