China is currently designing a regional economic layout for high-quality urban development, shifting its focus from the primary stage of beautifying cities to the next stage of profound urbanization aiming at strengthening industry. This is of high importance given that the urbanization rate of permanent residents by the end of 2019 was 60.60%, according to the National Bureau of Statistics of China. In the face of various factors such as the need to economize the intensive use of resources, urban stock development, and the need for urban constructions to maintain harmony with the surrounding ecosystem, regeneration has emerged as an efficient means to repurpose old residential districts. It conforms to the policy of stock planning and is one of the important methods to ensure the sustainable development of a city. Prioritizing the right attributes in renovation is one of the critical steps in the regeneration of old residential districts-instead of merely focusing on their selection and scoring by experts, more attention should be paid to the resident satisfaction (or the lack thereof) arising from them. Therefore, in this study, we have proposed a collaborative approach that requires communities to prioritize the appropriate aspects in urban renewal. This study employed the three-factor theory of customer satisfaction, to investigate the five attributes namely geographical location, infrastructure, traffic, residential management, and living facilities, of satisfaction and dissatisfaction of residents in the old city. This includes 327 samples based on the residents of Yanta old town in Xi'an. The asymmetric impact-performance analysis technique was used to explore, and quantify the asymmetric relationship between the attributes of old residential districts, and residents' satisfaction. The results proved that attributes were divided into three: excitement factors, performance, and basic factors, based on the asymmetric influence of attributes on residents' satisfaction. Residential management was into excitement factors, living facilities were categorized into basic factors, and the remaining three attributes were categorized into performance factors. The satisfaction of the residents regarding the renovation was maximized by comprehensively considering the performance of given attributes, adjusting the improvement strategies of each attribute, and further determining the focus of the renovation of the old residential districts. Simultaneously, it helped planners make more rational choices in urban renewal and sustainable development.
中国目前正在设计一个促进高质量城市发展的区域经济布局，将工作重点从城市美化的初级阶段转移到加强产业的深层次城市化阶段。考虑到截至 2019 年底中国常住居民的城市化率为 60.60%，这一点非常重要。面对资源集约利用、城市存量发展、城市建设与周边生态系统和谐共生等因素的需要，再生成为旧住宅区重新利用的有效手段。它符合存量规划的政策，是确保城市可持续发展的重要方法之一。在旧住宅区的再生中，优先考虑适当的属性是关键步骤之一——与其仅仅关注专家对其的选择和评分，不如更加关注居民对这些属性的满意度（或缺乏满意度）。因此，在这项研究中，我们提出了一种社区共同参与的方法，要求社区在城市更新中优先考虑适当的方面。本研究采用客户满意度的三因素理论，调查了五个属性，即地理位置、基础设施、交通、住宅管理和生活设施，以及老城居民的满意度和不满意度。该研究基于西安雁塔老城的居民，共采集了 327 个样本。采用非对称影响绩效分析技术，探讨并量化了旧住宅区属性与居民满意度之间的非对称关系。结果证明，根据属性对居民满意度的非对称影响，属性分为三类：兴奋因素、绩效因素和基本因素。住宅管理属于兴奋因素，生活设施属于基本因素，其余三个属性属于绩效因素。通过综合考虑给定属性的绩效，调整每个属性的改进策略，并进一步确定旧住宅区改造的重点，可以最大限度地提高居民对改造的满意度。同时，这有助于规划者在城市更新和可持续发展中做出更合理的选择。
