摘要：

大手町地区位于日本东京经济中心，寸土寸金的土地使其聚集众多全球性企业总部大楼，高层与超高层建筑鳞次栉比，平均容积率高达7.0 左右。如何使如此高密度的城市中心区在保障众多企业正常运营的同时实现都市再生，是大手町地区城市更新面临的最核心问题。本文系统剖析大手町地区整合周边资源、以种子基地为引擎、不动产证券化、产官学三方合作等都市再生策略，详细解读其“连锁型”接力更新过程；并以此为基础，针对我国城市更新提出政策保障、设计策略、服务管理三个层面的具体建议。

Abstract：

renewal process of Gearing Type in detail. Furthermore, aiming at urban renewal in China, this paper puts forward specific proposals of policy security, design strategy and service management on three levels.
