Internal Audit Scale,Self-interest Motivition Of Managers And Sticikiness Of Expenses

Cost management is the inevitable requirement of the long-term development of listed companies in China and the important level of strategic choice.In recent years,due to the impact of external economic environment fluctuations,the profit space of China's market gradually decreases.Under the requirements of industrial upgrading and transformation,cost management has become an inevitable requirement for the long-term development of China's listed companies.The traditional cost model assumes that costs and expenses increase or decrease with the increase or decrease of business volume,that is to say,the traditional cost and business volume are interdependent and completely symmetric.Anderson et al.put forward the concept of cost stickiness,in which the increase of cost is larger than the decrease of cost when the business volume goes up.This theory breaks the limitation of traditional cost state theory.Subsequently,more and more scholars at home and abroad have carried out further research on this issue.This article selects 2013 to 2017,996 data of Shanghai and Shenzhen a-share listed companies in the domestic and foreign related expenses viscous research,on the basis of combining the principal-agent theory,behavioral science theory,information asymmetry theory and relevant internal audit,relevant theories of managers' self-interest,size of internal audit,managers' self-interest and expenses to the relations between viscosity for empirical research.Through empirical analysis,the following conclusions are drawn: the listed companies in China have sticky expenses;There is a significant positive correlation between managers' self-interest motivation and expense stickiness.The higher the managers' self-interest motivation is,the stronger the expense stickiness of listed companies is.Internal audit scale can adjust the positive correlation between managers' self-interest motivation and cost stickiness.From the perspective of behavioral economics,this paper discusses the influence of managers' self-interested motivation on expense stickiness,and further studies the moderating effect of internal audit scale on the relationship between managers' self-interested motivation and expense stickiness.According to the research results of this paper,the following Suggestions are put forward for enterprises: first,enterprises should establish a sound incentive mechanism and supervision mechanism for managers;Second,enterprises should attach importance to internal audit scale.At the same time,The government should intensify efforts to improve the internal audit system.
