In order to improve the pertinence and effectiveness of social stability risk assessment of land requisition in construction projects, 22 social stability risk factors of land expropriation in construction projects were identified based on literature research and expert interviews. The risk factors were classified according to legality, rationality, feasibility and controllability, and a list of social risk factors of land expropriation in construction projects was constructed. The risk factor list was validated using engineering examples, and the evaluation results show that the combined risk index of the proposed land expropriation project is 0.24, which belongs to low social stability risk.
