中文摘要：

20世纪50年代中国近代建筑史主要以帝国主义和阶级斗争为主线索，改革开放以后出现了现代化的主线索。2016年“中国近代建筑史”（五卷本）的出版是中国近代建筑史研究的里程碑，也促进了对研究线索和理论框架的进一步思考。本文作者基于参与主编本书的经历，提出了X＋Y＋Z的框架，即近代建筑史研究需要同时思考外来的影响（X轴）、传统的继承（Y轴）和他学科的影响（Z轴）的三维取向，而不是任选其一。论文解释了作为X轴的民族主义背景下的“主体受容”、殖民主义背景下的“从属受容”、作为Y轴的传统的承传与创造，并探讨了作为Z轴的知识、权力、想象的共同体、民族主义、殖民主义、公共领域等理论对于中国近代建筑史研究的可借鉴之处。

In the 1950s, the history of Chinese modern architecture was mainly based on imperialism and class struggle. After the reforms and opening up, the main clue of modernization emerged. The publication of The History of Modern Chinese Architecture （5-volume） in 2016 is a milestone in the study of modern Chinese architectural history, as well as an opportunity for further study of the clues and theoretical framework. Based on the experience of editing this book, the author puts forward the framework of X＋Y＋Z, which means we need to think about the three-dimensional orientation： external influence （X-axis）, traditional inheritance （Y-axis） and other subjects influence （Z-axis） rather than to choose only one when we study modern Chinese architectural history. The paper explains X-axis including the ＂active acceptance＂ on the background of nationalism and ＂passive acceptance＂ on the background of colonialism, and the Y-axis including discusses Z-axis including the theories about knowledge public sphere and so on, which can be used for reference the traditional inheritance and creation. The paper also power, imagined community, nationalism, colonialism, in the study of Chinese modern architectural history
