在老龄化和城镇化的双重背景下，为老旧多层住宅安装电梯是提高老年人生活质量的重要举措。但是，由于住户之间的利益冲突，有些住户不愿意或者反对安装电梯，而安装电梯又是一个涉及全楼层住户的大型项目，如果有一位住户不同意合作，那么项目就很难实施。为了解决这一问题，本文研究了影响老旧多层住宅住户安装电梯合作意愿的因素， 通过相关理论，构建了老旧多层住宅住户安装电梯合作意愿影响因素的理论框架。并通过实证研究，发现了显著影响老旧多层住宅住户安装电梯合作意愿的因素，分析了各因素的作用方向和作用强度。以桂林理工大学教职工社区为案例，通过问卷调查收集数据，运用广义定序 logistic 回归模型和二元 logistic 回归模型，对数据进行了全样本和分楼层的回归分析，从而识别了具有显著性的影响因素。根据住户合作意愿影响因素，设计了老旧多层住宅住户安装电梯合作意愿提升的对策，并参考前文的理论和实证研究结果，提出了“外部环境激励、内部环境影响、安装电梯方案优化”的合作意愿提升对策，旨在营造一个有利于安装电梯的环境，提高项目成功实施的可能性。最后，针对桂林理工大学教职工社区多层住宅安装电梯项目，从实施主体、资金筹集、协商机制、住户费用分摊与补偿方式、电梯类型、加建方式、维护费用出资方式等方面，提出了安装电梯项目的实施建议。

Against the dual backdrop of aging and urbanization, installing elevators in old multi-story residential buildings is an important measure to improve the quality of life for the elderly. However, due to conflicts of interest among residents, some are unwilling or opposed to the installation of elevators. Since elevator installation is a large-scale project involving all residents of the building, it becomes difficult to implement if even one resident disagrees with the cooperation. To address this issue, this paper studies the factors influencing the willingness of residents in old multi-story residential buildings to cooperate in elevator installation. Through relevant theories, a theoretical framework for the factors influencing the willingness to cooperate in elevator installation was constructed. Empirical research identified significant factors affecting the willingness to cooperate, analyzing the direction and intensity of each factor’s effect. Taking the staff community of Guilin University of Technology as a case study, data was collected through questionnaires. The generalized ordered logistic regression model and binary logistic regression model were used to perform regression analysis on the full sample and by floor, identifying significant influencing factors. Based on these factors, strategies to enhance the willingness to cooperate in elevator installation were designed, proposing “external environmental incentives, internal environmental impact, and optimization of elevator installation plans” as measures to enhance willingness to cooperate, aiming to create an environment conducive to elevator installation and increase the likelihood of successful project implementation. Finally, for the multi-story residential elevator installation project of the Guilin University of Technology staff community, suggestions for the implementation of the elevator installation project were proposed, covering aspects such as the implementing body, fundraising, negotiation mechanisms, cost-sharing and compensation methods for residents, elevator types, construction methods, and funding methods for maintenance costs.
