我们使用国家统计局1997-2008年期间英国大型生产企业的微观数据来研究它们的生产率与大量研发活动之间的关系,无论是在生产单位本身,还是在同一企业集团拥有的其他英国报告单位。我们估计,与没有研发的企业相比,拥有大量研发的企业的全要素(收入)生产率平均高出14%左右。在没有研发的企业中,我们估计那些在英国其他地方有大量研发的企业集团在同一子行业的生产率平均高出约9%。对于本身拥有大量研发的企业,我们还使用动态规范估计当前生产率与过去研发支出之间存在显著的正相关关系,该规范允许特定于企业的“固定效应”和序列相关误差成分。
We use Office for National Statistics' micro data for large UK establishments in the production industries in the period 1997–2008 to study the relationship between their productivity and the presence of substantial R&D activities, either at the production unit itself, or at other UK reporting units owned by the same enterprise group. We estimate that total factor (revenue) productivity is on average about 14% higher at the establishments which have substantial R&D themselves, compared to those with no R&D. Among the establishments with no R&D themselves, we estimate that productivity is on average about 9% higher at those which belong to enterprise groups which do have substantial R&D elsewhere in the UK in the same sub-sector. For the establishments with substantial R&D themselves, we also estimate a significant positive relationship between current productivity and past R&D expenditure using dynamic specifications which allow for both establishment-specific ‘fixed effects’ and a serially correlated error component.
