In the theory of risk management, risk identification is the premise of risk management. Only through correct risk identification can we correctly recognize the existence of risk factors, and then select appropriate methods to deal with the existing risks. Risk identification refers to the use of systematic risk analysis methods to analyze potential risk factors and find out the reasons for the existence of this risk, which is a pre event link, that is, the work carried out before the risk occurs. Generally speaking, risk identification mainly includes risk sensing and risk analysis.
