与其他主要经济体相比，英国的商业研发与GDP的比率(BERD比率)相对较低。上世纪90年代，英国的BERD比率也出现了小幅下降，而其他主要经济体的BERD比率则略有上升。相对较低的BERD比率不能仅仅用英国与其他国家在部门或行业层面上的差异来解释。因此，人们有相当大的兴趣了解企业层面的研发投资决定因素。这份报告是由DTI委托进行的，目的是分析通过合并国家统计局的商业研究和发展数据库(BERD)和年度受访者数据库(ARD)而产生的样本公司的研发和生产率之间的联系。该分析估计的是私人研发回报率，而不是社会回报率，因为推动企业决策的应该是私人回报率。这项研究的一个关键目标是分析中小型企业(SME)的研发生产率。这一分析旨在与罗杰斯(2005)的结果进行比较，罗杰斯使用了20世纪90年代英国大中型公司研发的公开数据。
The UK has a relatively low ratio of business R&D to GDP (the BERD ratio) compared to other leading economies. There has also been a small decline in UK’s BERD ratio in the 1990s, whereas other leading economies have experienced small rises. The relatively low BERD ratio cannot be explained solely by sectoral or industry-level differences between the UK and other countries. There is, therefore, considerable interest in understanding the firm-level determinants of investment in R&D. This report was commissioned by the DTI to analyse the link between R&D and productivity for a sample of firms derived from merging the ONS’s Business Research and Development Database (BERD) and the Annual Respondents Database (ARD). The analysis estimates the private rates of returns to R&D, and not the social rates of return, since it is the private returns that should drive firms’ decisions. A key objective of this research is to analyse the productivity of R&D in small and medium sized enterprises (SME). The analysis is intended to allow comparisons to the results in Rogers (2005), which uses publicly available data on R&D in medium to large UK firms in the 1990s.
