Thought and delation about the development of critical regionalism in China [PDF]
, 2013 “批判的地域主义“在两个方面都具有批判性质,一是对当代世界范围内的主流文化和先进技术持批判态度,二是同时对怀旧的传统历史形式表示质疑。但近来此潮流似乎已经走入歧途(尤其是在中国),所有传统材料+现代形式的建筑都被冠以“批判地域主义“之名——这是否为一个本应相对严谨的理论又强行套上了主观的公式？本文试从批判地域主义理论的思想源头开始,将批判地域主义置于当下社会环境中进行一次批判性的再解读,讨论它在中国的研究意义以及出路。The"Critical Regionalism"has critical ...
