Core Viewpoint - The Ministry of Natural Resources has released a report highlighting typical cases of underground space development, showcasing innovative practices from 22 projects across 17 provinces, with a focus on urban parking solutions [1] Group 1: Project Overview - The underground parking facility in Wuhu City, located beneath Zhongshan Road pedestrian street and Mirror Lake, has been recognized as a demonstration case for underground transportation facilities [1] - The total construction area of the parking lot is approximately 38,000 square meters, providing over 800 parking spaces [1] Group 2: Benefits and Impact - The project effectively alleviates the long-standing "parking difficulty" issue in the commercial center and surrounding old residential areas of Wuhu City [1] - By implementing layered rights and three-dimensional development, the project achieves efficient composite utilization of the square, water body, and underground space, enhancing land use efficiency [1] - The initiative reflects the construction philosophy of "returning green space and lakes to the public," restoring ground landscape and lakeside ecology [1]

Core Viewpoint - The recent measures issued by the Guangzhou Planning and Natural Resources Bureau aim to optimize the development and utilization of underground space in Guangzhou, encouraging active participation from various sectors in the construction of underground spaces in super-large cities during the era of stock utilization [1][2]. Group 1: Development Guidelines - The measures support separate accounting for above-ground and underground building area, with a minimum underground development intensity of 0.2 for key urban functional areas and 0.1 for non-key areas near underground transit stations [1]. - Developers are encouraged to apply for underground space development, with the underground building area calculated separately from the above-ground area, and no transfer of underground area to above-ground calculations allowed [1]. Group 2: Cost Considerations - Given the high costs associated with underground construction, the measures allow for up to 30% of the underground self-operated commercial building area to be allocated for public underground spaces and connections [1]. - The measures support the reservation of space for self-operated convenience service facilities within the scope of underground transit construction, provided that it meets transportation and public service functions and complies with safety regulations [1]. Group 3: Land Pricing and Rights - The measures introduce land price incentives for underground space, including no comprehensive development fees for underground spaces developed through allocation on existing state-owned land, while commercial parts must undergo paid usage procedures [2]. - The pricing for the first transfer of underground space will be determined based on benchmark land prices, considering cost differences, and will implement a downward price reduction policy [2]. - The measures allow for phased payment of land transfer fees for underground spaces, with different payment methods specified for various supply modes [2]. - Support is provided for the separate confirmation of underground space rights, allowing rights holders to apply for new property rights certificates based on three-dimensional cadastral survey results [2].

Group 1 - The Shanghai Municipal Housing and Urban-Rural Development Committee's Science and Technology Committee has completed nearly 30,000 important projects over the past 40 years, contributing significantly to high-quality urban development in Shanghai [1] - The establishment of the Shanghai Construction Technology Development Foundation aims to facilitate the funding, management, and allocation of resources necessary for construction technology development, creating a positive cycle [3][5] - The Science and Technology Committee serves as a consulting body for major scientific and technological issues and policy recommendations, enhancing the macro-management capabilities of government departments [2][5] Group 2 - The Asia-Pacific Urban Technology Cooperation Network was established to strengthen horizontal connections among cities in the Asia-Pacific region, promoting international cooperation in various fields [8] - The Shanghai Municipal Construction Committee has initiated the establishment of four specialized research centers focusing on carbon neutrality, urban underground space utilization, water resource protection, and smart city management [23][25] - The recent Shanghai Housing and Urban-Rural Development Industry Technology Conference emphasized the theme "Empowering Technology, Innovative Development," aligning with national development strategies and promoting high-quality development in the Yangtze River Delta region [35][37]

Core Viewpoint - Shenzhen is accelerating its development of underground spaces to create a vibrant three-dimensional city, with a focus on utilizing underground resources from 2025 to 2035, as outlined in the newly released planning document [1][2]. Group 1: Planning and Development - The Shenzhen Municipal Planning and Natural Resources Bureau has identified 48 key areas for underground development, distributed across various districts [2][3]. - The development will focus on integrating above-ground and underground spaces, particularly around urban functional centers and transit hubs [3][4]. Group 2: Area Distribution - The distribution of the 48 underground development areas includes: - Nanshan District: 10 areas - Futian District: 8 areas - Bao'an District: 8 areas - Longgang District: 7 areas - Longhua District: 4 areas - Luohu District: 3 areas - Pingshan District: 3 areas - Guangming District: 3 areas - Yantian District: 1 area - Dapeng New District: 1 area [4]. Group 3: Functional Focus - The primary functions of these underground areas will include transportation facilities, municipal utilities, and commercial services, with an emphasis on connectivity between underground transit hubs and surrounding amenities [5]. Group 4: Economic Rationale - The development of underground spaces is deemed necessary due to Shenzhen's limited land area and high population density, which necessitates maximizing space utilization to support economic growth and urban living [6]. - Shenzhen's GDP is projected to reach 3.68 trillion yuan in 2024, highlighting the economic imperative for underground development [6]. Group 5: Transportation Infrastructure - By the end of 2024, Shenzhen's urban rail transit network is expected to reach 595.1 kilometers, with a network density of 0.30 kilometers per square kilometer, making it the most extensive in the country [7]. - The city aims to enhance the functionality of underground spaces, improve integration with transit systems, and ensure robust regulatory frameworks for future developments [7].
