Abstract Planning support systems (PSS) enabled by smart city technologies (big data and information and communication technologies (ICTs)) are becoming more widespread in their availability, but have not yet been fully recognized as being useful in planning practice. Thus, a better understanding of the determinants of PSS usefulness in practice helps to improve the functional support of PSS for smart cities. This study is based on a recent international questionnaire (268 respondents) designed to evaluate the perceptions of scholars and practitioners in the smart city planning field. Based on the empirical evidence, this paper recommends that it is imperative for PSS developers and users to be more responsive to the fit for task-technology and user-technology (i.e., utility and usability, respectively) since they positively contribute to PSS usefulness in practice and to be more sensitive to the potential negative effects of contextual factors on PSS usefulness in smart cities. The empirical analyses further suggest that rather than merely striving for integrating smart city technologies into advancing PSS, the way that innovative PSS are integrated into the planning framework (i.e., how well PSS can satisfy the needs of planning tasks and users by considering context-specificities) is of great significance in promoting PSS's actual usefulness.

无知是福？对 PSS 在实践中有用性的决定因素的实证分析

摘要 由智慧城市技术（大数据和信息通信技术（ICT））支持的规划支持系统（PSS）在其可用性方面变得越来越普遍，但尚未被充分认识到在规划实践中的有用性。因此，在实践中更好地理解 PSS 有用性的决定因素有助于改善 PSS 对智慧城市的功能支持。本研究基于最近的国际问卷（268 名受访者），旨在评估智慧城市规划领域的学者和从业者的看法。基于经验证据，本文建议 PSS 开发人员和用户必须对任务技术和用户技术（即实用性和可用性、分别），因为它们在实践中对 PSS 的有用性做出了积极贡献，并且对上下文因素对智慧城市 PSS 有用性的潜在负面影响更加敏感。实证分析进一步表明，不仅仅是努力将智慧城市技术融入推进 PSS 中，创新 PSS 融入规划框架的方式（即，PSS 通过考虑上下文特定性来满足规划任务和用户的需求的程度如何？ ) 对提升 PSS 的实际效用具有重要意义。
