| The management of cost plays a crucial role in the ordinary management of enterprises.With the development of globalization,Chinese enterprises have enhanced strength in worldwide economic competition,and then the management of cost has attracted more attention by managers and people who care about the profit of the company.In traditional cost analysis,the cost is separated as fixed costs and varied costs,and the cost is assumed as a linear function of the amount of business,which can be modeled as y=a+bx.However,as stated by Anderson et al.(2003),the sale and management cost is increased by 0.55% when the income increases by 1%,while the cost is only reduced by 0.35% with the 1% decrement of incomes,and this phenomenon was defined as cost stickiness.Then many researchers investigated the existence and cause,while only few studies on the industrial difference and influencing factors of financial structure.This paper investigates the cause of cost stickiness with respect to a financial index based on the data of A-share companies in Shenzhen stock exchange from 2011 to 2014.Besides,we also carefully discuss the characteristic and influence of the cost stickiness of each subproject.Theoretical analysis and experimental validation are combined in our study.Seven assumptions are proposed based on theoretical analysis.Data preprocessings are conducted firstly,and then statistics and regression analysis are implemented by SPSS.Numerical analysis shows several results as follows: 1).The cost stickiness is detected in A-share companies in Shenzhen stock exchange,and the management cost stickiness is much more significant compared with the sale cost stickiness;2).The industrial difference of cost stickiness is validated,and the strength and type of different industries are varied significantly;3).Enterprise cost stickiness has relationship with the financial structure.Finally,some suggestions on cost stickiness control are proposed based on theoretical and numerical analysis results. |
