摘　　要：运用断裂点概念和公式,分析比较京、津两市2012—2015年办公空间的发展格局及两城市间的相互作用与联系。研究表明:1)北京和天津两市的办公空间格局均呈现从市中心向外围不断扩展的态势,北京在中心城区以CBD—金融街—中关村为核心的三足鼎立式办公聚集区格局趋于增强,同时上地、亚奥、望京地区的办公空间集聚显现;天津受滨海新区建设发展的影响,由单中心向双中心转变,办公空间沿京津方向和滨海新区方向,呈组群扩展。2)城市内部办公活动集聚效果显著,北京办公空间分布方向性减弱,空间格局方向变化不显著,总体上呈"西北—东南"走势;天津办公空间分布由"南—北"走势,转向"西北—东南"走势,空间分布重心向南偏移的比较显著。3)利用断裂点公式,以城市从业人口、第三产业产值和写字楼数量作为城市规模指标,得出北京的吸引区范围较天津更大。同时,在区域发展进程中,北京的向心引力在不断增强,对区域的吸引和辐射也呈现显著增强的态势,随着天津滨海新区建设和京津城际轨道交通的建设,天津也正在逐渐发挥其港口城市的优势,与北京形成空间互补。Using the concept and formulas of break points, the authors make analysis and comparison of Beijing and Tianjin cities＇ 2012-2015 development pattern of office space and the interaction between the cities. The results show： 1）The office space pattern of Beijing and Tianjin city presents the expanding trend from the city center to the periphery. With CBD, financial street, and Zhongguancun office cluster as the core, the three pillar pattern in downtown Beijing tends to be enhanced. At the same time, Shangdi, Olympic, and Wangjing area office space agglomeration is emerging; Affected by the construction and development of Binhai new area, Tianjin shifts from single center to double center. The office space is expanded along the direction of Beijing- Tianjin and the Binhai new area. 2）The agglomeration effect of office activities within the city is remarkable. The directional distribution of Beijing office space was weakened. The directional change of spatial pattern was not significant, with a generally ＂ northwest-southeast＂ trend; Tianjin office space shifted from ＂ South - North＂ trend to ＂northwest - southeast＂ trend, and the center of spatial distribution shifted southward more significantly. 3） Using breaking point formula, with urban working population, the tertiary industry output va｜ue and the number of office as the city scale index, the conclusion shows that the attraction area of Beijing is larger than that of Tianjin. Meanwhile, in the process of regional development, the attraction force of Beijing is growing, and attraction and radiation areas also showed a significant enhancement trend. With the construction of Tianjin Binhai New Area and the Beijing-Tianjin inter-city rail transit, Tianjin is gradually taking advantage of a port city, and forming a complementary space with Beijing.
