| With the development of the socialist market economy system in China,the market competition faced by enterprises is becoming more and more intense,and the requirements of management standardization are higher and higher.A relatively perfect internal control management system can ensure the compliance and legal operation of enterprises and realize sustainable development.The internal control management of an enterprise is not good,which may cause chain reaction due to the outbreak of a risk point,which will lead to the failure of the enterprise to achieve the established goals,or even bankruptcy.This paper selects G nonferrous metals trading company as the research object.It is a large state-owned holding nonferrous metals trading enterprise.There are important defects in its internal control,such as the decision-making and implementation of bulk commodity trade,large amount of capital payment and so on.Some of its internal control does not exist,some are not perfect,and the major business operation mode is not mature.There are significant risks in trade finance business,and the huge receivables of downstream enterprises can not be recovered for a long time,so the risk of enterprises is huge.First of all,the paper summarizes and refines the relevant literature at home and abroad on internal control of enterprises,introduces the meaning,objectives,principles and relevant theoretical basis of internal control,and points out the characteristics of internal control of non-ferrous metal trading enterprises,which provides a theoretical basis for the writing of the paper.Secondly,through the data investigation,we have a detailed understanding of the basic situation,trade business process,overall production and operation of G nonferrous metal trading company and the operation of each nonferrous metal product trade business.Then,using individual interviews,data surveys and external customer surveys to comprehensively grasp the current situation of internal control,and then found that the main problems of the current internal control,including: the internal control environment needs to be improved,the lack of risk analysis and response ability,the lack of some internal control links and Implementation is not in place,the information communication is not smooth,and the effect of internal control supervision is insufficient.The main causes of the problems are: industry reasons,short-sighted behavior in the setting of business objectives,failure to establish a standardized system,failure to accurately grasp the key control points of internal control,management’s attitude to internal control is not firm enough,the construction of internal control environment is weakened,and the internal control system is lack of necessary supervision.Finally,according to the actual situation of the company,this paper puts forward the motivation,ideas and principles of internal control optimization,and makes it clear that "reasonable control of financing scale and increasing the compression of the two funds" are the key points of internal control optimization.From the perspective of the five elements of internal control,this paper puts forward some feasible internal control optimization measures,mainly including:optimizing the internal control environment;Carry out comprehensive risk assessment to improve risk response capacity;Improve the internal control management link,strengthen the implementation of internal control;Strengthen information communication;Optimize internal control and supervision. |
