Based on the analysis of literatures，interview practices and the theory of technology acceptance model，the paper shows the main factors and channels affecting the intention of lean construction implementation and further constructs a conceptual mode．We identify the measurement items of the formal survey questionnaire through project preparation，project analysis and exploratory factor analysis，and then test the conceptual mode by the empirical method．We arrive at the following conclusions: all factors affecting the intention of lean construction implementation reach the significance levels except the environmental factor which certifies that the conceptual mode we propose can better explain the regular pattern in the staff implementation process of lean construction．Some recommendations facilitating the implementation of lean construction in China’s enterprises are brought forward．
