摘要
基于文献分析,建构机构持股比例差异下分析师乐观评级影响高技术企业研发人力资本存量向研发产出转化过程的理论模型,并使用2011—2017年间A股汽车制造业上市企业样本,结合层次回归和门限回归对相关效应进行检验。实证分析结果在识别研发人力资本存量经由研发支出中介向研发产出转化过程的基础上,揭示机构持股比例较低状态下高技术企业研发支出向研发产出转化过程无法稳定实现的问题,以及机构持股比例较高时分析师乐观评级对高技术企业研发支出向研发产出转化的强化作用。
In this paper,based on the literature analysis,we open the"black box"of R&D process,and construct a theoretical model to illustrate how the analysts'optimistic rating will impact the transformation from stock of human capital to R&D output in high-tech companies with different proportions of institutional ownership.Then,we choose public listed automobile companies in A-share market from 2011 to 2017 as samples.We examined the effects with hierarchical regression and threshold regression.The empirical result verified the identification of transformation from stock of human capital to R&D output through R&D input.Also,it indicated that the R&D input cannot be steadily transformed into R&D output when proportion of institutional ownership is low;furthermore,when proportion of institutional ownership is high,analysts'optimistic rating would strengthen the transformation from R&D input to R&D output.
