Critical regionalism,on the one hand,is regarded as a substitute for post-modernism and at the same time,saves modern architecture.While on the other hand,because of its internal contradictions in the theory,critical regionalism receives criticism.The essence of the issue focuses on criticism and the methods of evaluation,focuses on traditional criticism adhering to explicit knowledge and neglecting tacit knowledge.Applying SECI model to re-look at these contradictions can find three levels of criticism and evaluation establised in practice and in the process of continuous critical reflection can eliminate these contradictions,thus making critical regionalism resume its deserved theoretical position.
