Abstract：The paper analyzed the overall situation in R&D investment of the companies listed in Shanghai or Shenzhen stock market and the effects of R&D investment by enterprise scales, ownership and industry concentration.The study showed that R&D investment intensity of the listed companies was stronger than designated scale industrial enterprises, but much lower than the global enterprises with active research and development.A U-shaped relationship was found between enterprise scale and R&D investment intensity, and the income elasticity of R&D investment of medium enterprises was lower than others.Private ownership of the enterprises was positive to improving the income elasticity of R&D investment, and there was no significant correlation between industry concentration and intensity of R&D investment.
