新能源行业成本粘性行为及其驱动因素研究

学术界关于成本费用粘性行为的研究主要集中于对费用粘性的分析,研究对象多以制造业为主,缺少特定细分行业的相关研究。选择当前受关注度较高的新能源行业为研究对象,以2007—2011年的新能源行业的财务数据为样本数据,对其成本粘性行为及其影响因素进行系统研究。实证分析结果表明:新能源行业上市公司存在成本粘性,当业务量增加1%时成本上升0.932 2%;当业务量下降1%时成本仅下降0.833%。非流动资产密度和负债水平有强化企业成本粘性行为的作用,而独立董事比例越高越能抑制成本粘性的发生。股东比例的作用机理尚不清楚,其效果还有待进一步的研究。

Research on New Energy Industry Cost Stickiness and Its Driving Factors

The research on cost stickiness behavior is mainly about sales ＆ administrative cost and manufacturing industry, lacking studies on particular niche business. Therefore, the new energy industry paid highly attention was chosen as the research object and an empirical analysis of cost stickiness behavior and its affecting factors was conducted. By analyzing the accounting data of China listed companies of new energy industry from 2007 to 2011, we find： （1） the listed companies from new energy industry did have cost stickiness behavior. When the sales increased by 1 %, the cost went up by 0. 9322% ; however, when the sales volume went down by 1%, the cost decreased only by 0. 833% . （2） Non--current assets density and debt levels have strengthened the degree of cost stickiness behavior and the higher the proportion of the independent directors is, the less the cost stickiness would be, but what role the proportion of shareholder has played is still not clear and further research is needed.
