Based on 80 literatures on the field of prefabricated construction projects risk research collected by CNKI, common risk identification techniques, risk classification methods and common risks for prefabricated construction projects was examined based on bibliometrics and text analysis. The research results indicate that literature review is common risk identification method. Environment, resources, construction, management and supply chain are common risk categories for prefabricated construction projects. The natural disasters, adverse weather conditions and the occurrence of force majeure, weak risk awareness among operators, quality issues with prefabricated components, poor feasibility and integration of design schemes, unfavorable working environment and surrounding environment during on-site hoisting operations are common risk factors for prefabricated construction projects. In order to provide reference for risk management of prefabricated building projects，the countermeasures and suggestions are proposed to prevent the occurrence of risks.
