| With the continuous development of the social economy and the continuous evolution of technology,new risks are constantly emerging in the market.On this basis,the academic community has begun to realize that the implementation of internal control is inseparable from the support of risk management,and the emphasis on enterprise operational risk management system is gradually deepening.COSO-2017 Enterprise Risk Management Framework closely links enterprise risk management and enterprise value,focusing on the integration of risk management with strategy and performance.COSO-2017 is based on the original risk management framework,further updating the connotation of risk management and enhancing people’s attention to comprehensive risk management.The trust industry has the characteristics of high risk and high complexity,because the main body of trust companies will be affected by information asymmetry,and driven by the high uncertainty of risk and capital profit pursuit in the financial industry,the problem of internal control of trust companies is constantly emerging,even the perfect internal control system is difficult to avoid internal control risks.It can be seen that it is very necessary to study the internal control of trust companies.This article will evaluate the effectiveness of the internal control system of Z Trust Company based on the internal control guidelines issued by the state.Based on relevant literature at home and abroad,this paper analyzes the relationship between internal control and comprehensive risk management.Based on the comprehensive risk management theory,the Basic Standards for Enterprise Internal Control and its supporting guidelines,the internal control guidelines of trust companies,combined with the current situation of internal control of Z Trust Company and the20 basic principles corresponding to the five elements of COSO-2017,an internal control effectiveness evaluation system was constructed.In this paper,the analytic hierarchy method and the fuzzy comprehensive evaluation method are used in the internal control evaluation method,and it is found that although Company Z currently has a series of internal control systems,there are still some design flaws,or the system is not well implemented.At the same time,the problems and causes of Company Z were studied and analyzed,and corresponding suggestions were put forward to provide reference for the internal control evaluation of other enterprises in the trust industry. |
