摘要
以披露研发信息的信息业与制造业上市公司为样本,针对其行业特征以及对科研投入的依赖性进行分析,利用面板数据建立多元线性回归方程模型,考察科研投入与企业绩效的关系。结果表明,企业科研投入与盈利能力之间的关系并不明显,但对企业成长能力有显著的促进作用;高研发密度和高效率的人工费用投入,以促进信息业主营业务收入增长能力和整体盈利能力增长速度的提高,对制造业主营业务收入的增长能力也有显著的贡献。
Choose information industry and manufacture industry listed companies which released the R＆D information as samples, the features and the dependency degree of R＆D expend of the samples are analyzed. By using the panel data, multi-linear regression models are established to investigate the relationship between R＆D expend and enterprise operating performance. The main empirical findings are following： There is not a fixed linear regression relationship between enterprise R＆D expend and profit ability; Enterprise R＆D expend has a significant promotion to enterprise growth ability; High density of R＆D expend and high effectiveness of human capital input could promote the growth ability of revenue and ROA of information industry which also has a great contribution to the growth ability of revenue of manufacture industry.
