Abstract:Accompanying with the promotion of joint construction of the "Belt and Road" initiative, mining investment in countries along the route has increased steadily. Based on the integrated analysis framework of international investment risk, a "four level" indicator system for mining investment risk evaluation is proposed from two dimensions, they are social general environment and industry general environment. Then, an important tool of grey system theory, grey correlation analysis is used to conduct empirical research on the indicator system. It is indicated that the degree of political stability is the primary factor affecting the risk of mining investment, followed by diplomatic relations, infrastructure construction, mineral resource endowment, external single investment, and national education level; The research results of risk assessment by country indicate that Vietnam, Indonesia and other countries are low-risk, Kazakhstan, Poland and other countries are medium risk, and Pakistan, Iran and other countries are high-risk.
