开发利用地下空间是拓展城市空间、解决“大城市病”的重要途径,土地开发利用逐渐由平面走向立体。与此同时,地下空间权属管理的问题也日渐显现。当前中国地下空间产权管理滞后于开发建设,全面分析当前地下空间产权管理政策情况,有针对性地提出应对策略,对于完善中国的城市地下空间法律制度、优化国土空间格局具有重要意义。本研究通过梳理中国地下空间领域法律法规,结合各城市实际利用情况,厘清当前地下空间产权管理存在的主要问题,并对地下空间利用问题的难点进行剖析。通过对比各地地下空间权属管理现状,借鉴吸收新加坡、日本的先进管理经验,提出完善中国地下空间产权管理的几点建议。

The development and utilization of underground spaces are essential strategies for addressing "urban disease" and expanding urban space, land use is gradually changing from plane to three-dimensional. In the meantime, the problem of ownership management of underground space is apparent. Currently, ownership management in China's underground space lags behind its development and construction. A comprehensive analysis of the current policies regarding ownership management in underground spaces, coupled with targeted strategies, holds significant importance in improving China's urban underground space legal system and optimizing the national land spatial structure. This study, through a review of China's legal and regulatory framework in the field of underground spaces, combined with an assessment of the actual utilization in various cities, aims to identify the primary issues in ownership management concerning underground spaces. The study further delves into the complexities of underground space utilization issues. By comparing the current state of domestic and international underground space ownership management, drawing inspiration from advanced management experiences in countries like Singapore and Japan, the study proposes several suggestions to enhance ownership management in China's underground spaces.
