The Mediating Effect of Value Creation in China High Tech Enterprises
With the high-tech enterprises as samples,the mediating effect between the two factors during the value creation is investigated.The research result shows that the impact of R&D expenditure on ROA and ROE is significantly positive.The relationship between R&D rate and firm value is irrelevant.At the same time,no significant correlation between the R&D and R&D breadth,while R&D depth shows a significant positive correlation with R&D rate at 1 % of the significance level.The higher the R&D rate,the stronger the R&D depth.R&D breadth and R&D depth are significant mediating variables between R&D costs and firm performance,but they are not significant mediating variables between R&D costs and firm market value.
