In order to carry out policy analysis and research more scientifically and to evaluate whether the existing fabricated construction policy system is complete or not,a three-dimensional analysis framework is built based on policy tools,namely,the policy tools dimension,the prefabricated construction agents dimension and the industrial value chain dimension. With the aid of it,using the content analysis method and the quantitative analysis method,this paper conducts a research on 13 prefabricated construction policy texts in China. It is concluded that the policy tools of environmental-type and supply-type are too much,while policy tools for enterprises and scientific research institutions are missing and policy tools in the dimension of the chain of prefabricated construction industry lag behind the value realization of the prefabricated construction,then some proper policy suggestions are proposed.
