Abstract

Daily travel distance in urban China has substantially increased. The spatial layout of the 15-minute neighborhood, which supports local living and encourages walking and biking, was detailed in the Urban Residential District Planning and Design Standards in China in 2018. This study investigates the impacts of the 15-minute neighborhood described in the 2018 standards on activity space, using mobile network data in Qingdao, China. A total of 42,991 subscribers of China Mobile are randomly sampled. The 15-minute neighborhood attributes are objectively measured for sampled residents individually. Our study shows that not all 15-minute neighborhood attributes are associated with smaller activity space. Commercial retail services and green open space, which were found to increase walking and physical activity, do not reduce activity space. On the other hand, public services such as primary school and middle school, bus stops, neighborhood centers, and sports facilities within walking distance are positively associated with smaller activity space.

活动空间与15分钟街区——基于青岛市大数据的实证研究
中国城市居民的日常出行距离大幅增加。15分钟社区的空间布局支持当地生活,鼓励步行和骑自行车,在2018年的中国城市住宅区规划设计标准中有详细说明。本研究利用中国青岛的移动网络数据,调查了2018年标准中描述的15分钟社区对活动空间的影响。随机抽取中国移动用户42991名。对抽样居民的15分钟社区属性进行了客观测量。我们的研究表明,并非所有的15分钟社区属性都与较小的活动空间有关。商业零售服务和绿色开放空间增加了步行和身体活动,但没有减少活动空间。另一方面,步行范围内的中小学、公交车站、社区中心和体育设施等公共服务与较小的活动空间呈正相关。
