Risk of corporate social responsibility (CSR) refers to the possibility and consequences of the potential lack of CSR, which will cause damage and loss to society and enterprises. Hence, scientific evaluation of CSR risk is conducive to enterprises to take timely risk response measures and reduce potential risk factors. In order to fully reflect the CSR risk, a comprehensive risk evaluation index system is established from four dimensions of corporate stakeholders, law, environment and charity. In addition, hesitant fuzzy language is used to describe the CSR risk information, so as to reflect the uncertainty in the process of risk judgment. Considering the complexity of the CSR concept and the possible discreteness of risk results, the hesitant fuzzy language-cloud model is established to evaluate CSR risk level. Finally, utilizing China Huaneng Group as a case to apply the CSR risk evaluation model, it is found that the overall CSR risk level of Huaneng is relatively low. Through further comparative and hierarchical analysis, it is found that the CSR risk of community stakeholders is relatively high, and the CSR risk of legal, environmental and charitable is relatively balanced.
