摘要
以2009-2013年沪深两市A股上市公司为研究对象,对我国连续五年排名前500强企业的研发投入强度进行考察。研究发现,研发投入强度平均为2%左右,最大值超过10%,且总体呈增长趋势;国有企业的研发投入整体水平低于非国有企业;高新技术企业研发投入整体高于非高新技术企业;不同行业RDI存在显著差异,其中RDI较大的行业依次是通讯和通讯设备业、机械设备制造业及汽车及零部件业,RDI较小的行业依次是电力、石油、天然气、化工及其他制造业。排名前500强企业平均研发投入额度也大幅增长,其增长速度是非连续排名500强企业的2倍多,表明对研发的高度重视是企业稳居500强的重要因素之一。
The listed companies in the A share of Shanghai and Shenzhen stock markets from 2009 to 2013 were used as the research objects in this paper which has investigated on research and development(R&D) investment intensity of enterprises ranking in "Top 500" consistently for five consecutive years in China. The analysis has found that for R&D intensity, the average is around 2% and maximum is over 10%, and it shows an increasing trend in general; The overall level of R&D investment of state-owned enterprises(SOE) is lower than that of non-state-owned enterprises, and the overall level of R&D investment of high-tech enterprises is higher than that of non-high-tech enterprises. The analysis has also found that there are significant differences in RDI in different industries, and industries with higher RDI are the communication and communication equipment industry, the machine equipment manufacturing industry, followed by the automobile and spare parts industry, while the power, oil, natural gas, chemical industries and other manufacturing have lower RDI. In view of the overall situation, paying more and more attention to R&D is the common characteristic of enterprises ranking in "Top 500" for five consecutive years, which illustrates that attaching great importance to R&D is a significant factor determining whether enterprises can be listed in "Top 500" consistently.
