利用手机信令数据识别上海市域内手机用户的工作地和居住地,获取就业者的通勤数据,测度上海中心城的就业中心体系。首先用就业者工作地数据生成就业密度分布图,基于中心城的就业密度识别就业中心。随后,用就业者工作地和居住地数据分别从就业密度和通勤联系两方面测度各中心的能级、分析各中心的腹地和势力范围。研究发现:①上海中心城的就业中心呈主中心强大的弱多中心体系;②就业密度越高的中心与其他地区的通勤联系一般也越强,但通勤联系在各中心间的差异更显著;③能级越高的中心腹地面积越大,但势力范围不一定越大;④相比于能级,职住功能混合度对职住平衡的影响更大;⑤缺少就业中心的地区势力范围呈交替状。本研究一定程度上能有助于解决既往就业中心体系研究因空间单元较大、缺少通勤数据在中心识别、通勤联系测度等方面受到的局限,希望能为构建上海中心城就业多中心体系提供帮助。 |

The purpose of this study is to explore the employment center system in the central city of Shanghai by using commuting data obtained from mobile phone signaling data in Shanghai. Based on the signaling data it is possible to identify the phone users' home residence and where their employment is. We compile the employment density map using the employment places data in order to identify the employment centers in Shanghai. Then the employment center system is measured based on two perspectives, namely employment density and commuting connection. We measure the level, the hinterland and influence sphere of each employment center in Shanghai central city. Our main conclusions are as follows: firstly, the employment center system in Shanghai central city is a weak multi-centric system with a strong primary center. Secondly, centers with higher employment densities also contain stronger commuting connections to other areas, and the discrepancies of commuting connections between centers are even more significant. Thirdly, centers with higher levels also have larger hinterlands, but their influence spheres are not necessarily larger. Fourthly, the mixed degree of residential and employment land use is a more significant determinant of the residential and employment land use pattern balance of employment center than the level of the center. Finally, influence spheres are alternately distributed in areas that lack employment centers. To some extent, this paper helps to solve the problems of identifying employment centers and measuring commuting connections. Previous studies have been unable to perfectly identify such centers due to either an overly large spatial unit of measurement or lack of commuting data. This paper will be helpful for constructing multi-center employment system in the central city of Shanghai. |
