Abstract

Despite the thriving development of metro-led urban underground public space (UUPS) and its significant benefits and costs, there remains a critical research gap in understanding and evaluating its efficiency. This paper intends to improve the post-evaluation system of metro-led UUPS by proposing an efficiency evaluation framework based on data envelopment analysis. The public and the private sectors are taken as different coexisting decision-makers, and a pair of linear programming is built accordingly (with different assignments of discretionary and non-discretionary inputs) for each decision-making unit. The directional vector is calculated based on CRITIC weights to model the searching process of referential cases in terms of urban renewal. The empirical study of twenty metro-led UUPSs in central Shanghai reveals that (1) the proposed evaluation framework is feasible and discriminative, (2) the efficient form of metro-led UUPS in Shanghai is mainly limited to a compact pattern with a low proportion of pure public space, (3) the essential solution to promote efficiencies is closer cooperation between different parties, and (4) efficiency evaluation is crucial to avoiding the “the-more-the-better” type of development. The findings of this study are expected to shed light on the future planning and operation of metro-led UUPS.

基于dea的地铁主导城市地下公共空间效率评价方法

尽管地铁主导的城市地下公共空间（UUPS）蓬勃发展，其效益和成本显著，但在认识和评估其效率方面仍存在重大的研究空白。本文提出了一种基于数据包络分析的效率评价框架，旨在完善城域ups的后评价体系。将公共部门和私营部门视为不同的共存决策者，并相应地为每个决策单元构建一对线性规划（自由裁量和非自由裁量输入的分配不同）。基于CRITIC权重计算方向向量，模拟城市更新参考案例的搜索过程。通过对上海市中心城区20个地铁主导UUPS的实证研究表明：(1)本文提出的评价框架具有可行性和判别性；(2)上海地铁主导UUPS的效率形态主要局限于紧凑格局，纯公共空间比例较低；(3)提高效率的根本解决方案是各方更密切的合作；(4)效率评价是避免“越多越好”型发展的关键。这项研究的结果有望为地铁主导的UUPS的未来规划和运营提供启示。

期刊介绍： Underground Space is an open access international journal without article processing charges (APC) committed to serving as a scientific forum for researchers and practitioners in the field of underground engineering. The journal welcomes manuscripts that deal with original theories, methods, technologies, and important applications throughout the life-cycle of underground projects, including planning, design, operation and maintenance, disaster prevention, and demolition. The journal is particularly interested in manuscripts related to the latest development of smart underground engineering from the perspectives of resilience, resources saving, environmental friendliness, humanity, and artificial intelligence. The manuscripts are expected to have significant innovation and potential impact in the field of underground engineering, and should have clear association with or application in underground projects.
