Risk Evaluation Model of Overseas Mining Investment Based on Grey System Theory

Risk Evaluation of Overseas Mining Investment Based on a Support Vector Machine

“…Second, it relies mainly on artificial design features and inevitably involves the subjective factors of the researchers, and the characteristics of the design are too targeted and incomplete. Third, the traditional linear method also has strong linear settings, but the impact of various factors on risk is often nonlinear [3][4][5]28]. In recent years, the support vector machine has emerged as an artificial intelligence method based on statistical learning theory [29][30][31][32], which has better generalization performance, has a global optimal solution, and can effectively solve the computational complexity of the linear model via kernel mapping and linearization etc.…”

“…The specific evaluation flow based on SVM is shown in Figure 3. Legal system (level of legality) (2) Risk evaluation index system Based on the existing results achieved, 34 indexes of 16 items in 7 categories are selected as the risk assessment indexes of overseas mining investment (Table 1) [3][4][5]28]. After extensive investigation and research, according to the characteristics and measurement attributes of each index, the 0-10 value assignment criterion is set.…”

“…The South African government encourages foreign mining investment, and it has a close and friendly relationship with China, so South Africa is one of the areas that Chinese mining enterprises focus on. However, the overseas investment project is large, the cycle is long, and the unpredictable factors are numerous, so the resource-based enterprises face a greater risk [3][4][5]. Therefore, to promote the sustainable, rational, orderly, and healthy development of overseas mining investment and to guide enterprises in the scientific assessment and prevention of overseas mining investment risks, an objective project is large, the cycle is long, and the unpredictable factors are numerous, so the resource-based enterprises face a greater risk [3][4][5].…”

Therefore, to promote the sustainable, rational, orderly, and healthy development of overseas mining investment and to guide enterprises in the scientific assessment and prevention of overseas mining investment risks, an objective summary of the rules of overseas mining investment and protection against investment risks has strong research value [4,[6][7][8][9][10][11][12].…”

Therefore, the aim of the present research was to explore how to use scientific methods to perform a quantitative and comprehensive evaluation of the risks faced by China's mining overseas investment, so as to guard against the risks of mining enterprises' overseas investment and protect the rights and interests of China's resources.…”
