经济流对于城市间经济联系的强度和各城市间经济的依赖性具有直观反映，对于分析城市群各城市间的经济联系问题具有重要的借鉴意义。本文借助万有引力模型，对京津冀城市群各城市的经济流强度及河北省11市对京津两市的经济隶属度进行计算，发现当前京津冀协同发展的实际情况与顶层设计的政策目标存在偏差，“京津冀”协同发展在实践中更多呈现为“京津廊”发展。因此，亟需由“京津廊”到“京津雄”再到“京津冀”，实现循序渐进的协同发展。综合考虑影响经济流强度及隶属度的因素，结合京津冀协同发展的现状和困境，本文提出从产业、交通和民生等方面入手，发挥北京辐射作用、促进京津冀产业转型协同，完善交通基础设施、构建区域经济联系网络，提升居民幸福指数、促进人流合理均衡。

Economic flow can reflect the intensity of economic connection between cities and the dependence of economy among cities, which is of great significance for the analysis of economic connection among cities in urban agglomeration. Based on this, this paper, with the help of the gravity model, combined with the perspective of economic flow, calculates the economic flow intensity of each city in the BeijingTianjin-Hebei Urban Agglomeration from 2014 to 2019 and the economic membership degree of each city to the other two cities. Combined with the analysis of the development process of Beijing-Tianjin-Hebei, it finds that the current collaborative development of Beijing-Tianjin-Hebei is more limited. The collaborative development of "Beijing-Tianjin-Langfang" needs to be solved step by step, from "Beijing-TianjinLangfang" to "Beijing-Tianjin-Xiongan" and then to "Beijing-Tianjin-Hebei". To solve this problem, we need to start with economy, transportation, people's livelihood and industry. Beijing should play a radiating role in promoting the coordinated development of Beijing, Tianjin and Hebei, improving the transportation infrastructure, building a regional economic network, improving the happiness index of residents, promoting the transfer of population between cities, and promoting the coordinated transformation of Beijing, Tianjin and Hebei industries.
