知识价值增值能力研究——基于黑龙江省上市公司的证据

采用市账率指标测量企业的知识资本,并利用净资产和净利润指标分别测算了企业的有形资产和价值,将线性回归模型和二因素方差分析相结合,构建了知识价值增值能力测量模型。以2010年黑龙江省21家上市公司为样本,对知识与价值增值能力之间的关系进行了实证研究。实证分析结果表明:知识对价值形成的影响是间接的,知识通过促进有形资产的价值增值能力提升而实现价值增值;当企业的资产规模较大时,知识与有形资产在价值增值上存在交互效应,知识能够极大提高有形资产的价值增值能力;当企业资产规模较小时,知识的价值增值能力不显著。

Based on Evidence from Listed Companies in Heilongjiang Province

This paper uses the index of P/B to estimate knowledge capital of company,and uses net assets and profits to estimate the tangible assets and value of enterprise.And it constructs the model of evaluating knowledge value-added ability by combining the linearity regression model with the two-factor variance analysis.The results obtained through the empirical analysis on twenty-one listed companies in Heilongjiang 2010 shows as follows：the influence of knowledge on value formed is indirect;knowledge realizes value-added by improving the value-added ability of tangible assets;knowledge and tangible assets affect each other on value-added,and knowledge can accelerate value-added when company＇s asset scale is large,while this ability is not obvious when the asset scale of company is small.
