摘　　要：【目的】精准获取老年人对橱柜使用的需求,通过构建结构方程模型分析适老化橱柜设计的关键影响因素,为设计适老化橱柜及制定其产品市场营销策略提供重要的数据支持。【方法】以60岁以上的老年人为研究对象,采用问卷量表法,通过发放457份有效问卷收集影响适老化橱柜设计的自变量指标数据,并运用李克特五级量表分析,量化各指标对适老化橱柜设计的影响度。从材料、尺寸、布局、功能、色彩和智能6个方面选取36项设计指标,以创新性作为中介变量,消费意愿作为因变量,通过偏最小二乘结构方程模型(PLS-SEM)对影响适老化橱柜设计的关键因素进行实证分析。【结果】1)在量表信效度检验中,布局、材料、尺寸、功能、色彩、智能、创新和消费8个维度的克隆巴赫系数均高于0.86,各测量题项间具有较强的内部关联性和一致性;组成信度均超过0.8,进一步证实量表具备高度的可靠性;平均抽取变异量(AVE)均高于0.7,显示出各变量具备良好的聚合效能,本研究构建的适老化橱柜设计测量模型在信度与效度方面均具有良好表现。2)采用amos软件对量表进行验证,区分效度检验各个维度所对应的AVE平方根都高于它与其他所有变量的相关系数的平方值,证明各变量之间具有良好的区分效度,检验成立。3)在PLS-SEM建模中显示构成各维度的因子荷载系数均较高,但不同指标在其所属维度内的荷载系数存在差异,应优先考虑荷载系数较高的指标,他们对潜在变量的解释能力更强。4)通过假设验证,H1~H6的路径系数均通过显著性检验(P<0.05),H7~H12对不同路径的间接效应通过显著性检验(P<0.05),表明先前假设在一定显著性水平下成立。【结论】研究结果得出一系列对适老化橱柜设计至关重要的影响因素,功能对购买意愿的影响系数最高,智能因素的影响系数相对较低,产品的功能特性【Objective】To accurately capture the needs of elderly individuals regarding cabinet usage by constructing a structural equation model to analyze the key factors influencing the design of age-friendly cabinets.The results provide important data support for the design of age-friendly cabinets and the formulation of corresponding product marketing strategies.【Method】This study focused on elderly individuals aged 60 and above,using a questionnaire survey method.A total of 457 valid questionnaires were collected to gather data on the independent variables affecting the design of age-friendly cabinets.The Likert 5-point scale was used to analyze and quantify the impact of each indicator on the design of age-friendly cabinets.Then,36 design indicators were selected from six aspects:materials,dimensions,layout,functionality,color,and intelligence.Innovation was considered as a mediating variable,and consumer willingness as the dependent variable.A partial least squares structural equation model(PLS-SEM)was employed to empirically analyze the key factors influencing the design of age-friendly cabinets.【Result】1)In the reliability and validity test of the scale,the cronbach’s alpha values of the eight dimensions-layout,materials,dimensions,functionality,color,intelligence,innovation,and consumer willingness were all above 0.86,indicating strong internal consistency among the measurement items.The composite reliability values exceeded 0.8,further confirming the scale’s high reliability.The average variance extracted(AVE)values were all above 0.7,demonstrating good convergent validity.The measurement model of aging cabinet design constructed in this study has good performance in terms of reliability and validity;2)The scale was verified using AMOS software,and the square roots of AVE for each dimension were higher than the square values of its correlations with all other variables,proving good discriminant validity;3)In the PLS-SEM model,the factor loading coefficients of the dimensions were relatively high,b
