For the conventional investment risk assessment model with stochastic simulation method to evaluate investment risk, it is difficult to calculate the weight of risk evaluation index, which is with a low accuracy of investment risk and benefit evaluation. To address this problem, a risk assessment model for industry investment in marine foreign trade economic zone based on support vector machine (SVM) is proposed in this paper. The evaluation index system of industry investment risk is constructed from two aspects of systematic risk and nonsystematic risk. The weight of each investment risk evaluation index is calculated by analytic hierarchy process, and the 3 industry investment projects are empirically analyzed by using the proposed model. The results show that the proposed model realizes the analysis and evaluation of risk through empirical analysis.
