A risk evaluation index system for mineral resources overseas investment was built up after fully analyzing the risk factors in mining industry overseas investment.The current popular mining investment risk evaluation methods had their deficiencies for they considered either solely subjective knowledge or only objective information.By integrating G1 method with coefficient of variation method，we presented a risk evaluation model for mineral resources overseas investment named G1-coefficient of variation，which was based on dynamic combination weighing method.We also carried out an instance analysis and the results show that the model，which can be used for investment decision-making，compensates for the deficiencies of evaluation index single weighing method.Dynamic combination weighing method had the advantages of both subjective weighing method and objective weighing method in that it took into consideration both experience and wisdom of experts and new changes in objective conditions.The established investment decision-making model provided for a more direct way of analyzing and comparing investment risk.
