[Abstract]:Cost habit is an important concept in the field of management and management accounting, which is used to reveal the relationship between enterprise cost and business volume. In the traditional cost habit model, the cost can be divided into variable cost and fixed cost according to cost habit. The relation between cost and business volume conforms to the relation of y = a + bx, a represents the fixed cost, b represents the marginal change cost, that is, the cost and the traffic are directly related to the linear relationship, the increase and decrease of the cost and the business volume is symmetrical, and the marginal change of the cost is not affected by the change direction of the traffic volume. According to the traditional model of cost habit, the driving factor of total enterprise's total cost is business volume, regardless of other factors such as the direction of the change of business volume, whether the volume of business is up or down, the fluctuation range of total cost is the same. This traditional cost analysis is too simple, although it is easy to understand and master the staff, but it is overly idealization, ignores many influential factors in practice, and does not fully reveal the relationship between total cost and business volume, The actual situation of cost management is not completely consistent with the actual situation. Later, some scholars put forward the idea of cost stickiness. The concept of cost stickiness refers to a kind of asymmetry, and when the marginal rate of change of enterprise cost varies with the traffic volume in different directions, there is no symmetry. When the business volume of the enterprise is increased, the growth rate of the cost is higher than the reduction rate of the cost when the business volume is reduced. The cost stickiness can be measured by the difference of the marginal rate of change in the different direction of the business volume, and the viscosity of different research objects can be compared with the size of the difference. It is worth noting that not all asymmetry is cost-viscous, and if the traffic volume decreases, the speed at which the cost is reduced is greater than the increase in the increase in the volume of traffic, although this phenomenon is also non-symmetrical, but this is not cost-viscous, but an anti-stick performance. Therefore, at the time of research, it is not only necessary to check whether the cost varies with the different direction of the business volume or not, more attention is paid to the concrete expression of asymmetry, the analysis growth rate and the reduction rate are lower, the growth rate is higher than the reduction rate, which is the viscosity of the cost. The rate of growth is lower than the rate of decrease is anti-adhesive. In this paper, the financial data of Shanghai-Shenzhen stock market for 2005-2011 was studied, and the traditional cost model was questioned by empirical data. This article includes the following six parts: In the first chapter, the thesis introduces the background and significance of the topic selection, and also expounds the research methods and points of innovation in this paper. The second chapter is a review of literature, which mainly deals with the literature of the domestic and foreign cost viscous research literature. Review and review. Chapter 3 discusses the formation of First of all, the three concepts of cost stickiness, cost stickiness and total cost are listed, the difference between the three concepts is analyzed in detail, and then the cause of the cost stickiness is also analyzed. The fourth chapter examines the existence of the total cost stickiness of listed companies in our country, the change of viscosity on time span, and compares the differences between cost stickiness, cost stickiness and total cost stickiness, and concludes that the cost stickiness is the biggest and the total cost is sticky. It's the most cost-sticky conclusion. It's also about the total cost. The fifth chapter discusses the difference between the total cost and viscosity of listed companies in 11 industries in China. The characteristics of industry differences are summarized and explained. Negative effects of this cost stickiness The countermeasures and suggestions are put forward. Chapter 7 is the summary of the whole text. The contribution and research bureau of this paper are pointed out on the basis of summarizing the whole text. Based on the analysis of the financial data of 1458 enterprises from two cities in Shanghai and Shenzhen in 2005-2011, the author finds that: (1) The total cost stickiness of listed companies in our country; In sum, or simply consider the operating cost, there are also cost stickiness, cost stickiness, and the maximum cost stickiness, the lowest total cost and the smallest cost; (3) the total cost viscosity decreases gradually with the increase of time span (4) GDP The bigger the growth rate, the bigger the total cost viscosity (5) the larger the debt-liability ratio, the bigger the total cost stickiness (6) there is obvious industry difference in the total cost stickiness, agriculture, forestry, animal husbandry, social service industry, fishery, manufacturing industry, information technology industry, mining and mining industry. There are cost stickiness in the construction industry. The innovation of this paper lies in: (1) on the basis of the research results of the existing cost, the concept of cost is carried out. In this paper, the concepts of cost stickiness, cost viscosity and cost viscosity (i.e. total cost viscosity) are analyzed, compared with the three concepts, and compared with the three concepts, the cost is proved respectively. The existence of sticky, cost-viscous, and cost-viscous (i.e., total cost viscosity). When the cost is sticky, the relationship between the cost and the business volume is deeply excavated. (2) The industry difference of total cost viscosity is also discussed in this paper.
