Abstract

Research and Development (R&D) indicators are used to facilitate international comparisons and as targets for research and innovation policy. An example of such an indicator is R&D intensity. The decomposition of the aggregate corporate R&D intensity is able to explain the differences in R&D intensity between countries by determining whether is the result of firms’ underinvestment in R&D or of the differences across sectors. Despite its importance, the literature of corporate R&D intensity decomposition has been developed only recently. This article reviews for the first time the different methodological frameworks of corporate R&D intensity decomposition and how they are used in practice, shedding light on why sometimes empirical results seem to be contradictory. It inspects how the use of different data sources and analytical methods affect R&D intensity decomposition results, and what the analytical and policy implications are. The article also provides methodological and analytical guidance to analysts and policymakers.

企业研发强度分解：不同的数据，不同的结果？

摘要

研究与开发（R＆D）指标用于促进国际比较，并作为研究与创新政策的目标。这样的指标的一个例子是研发强度。公司研发总强度的分解能够通过确定企业研发投入不足还是部门间差异来解释国家之间的研发强度差异。尽管具有重要意义，但企业R＆D强度分解的文献才刚刚开发。本文首次回顾了公司研发强度分解的不同方法框架，以及它们在实践中的使用方式，阐明了有时实证结果似乎矛盾的原因。它检查了不同数据源和分析方法的使用如何影响R＆D强度分解结果，以及分析和政策含义是什么。本文还为分析人员和决策者提供了方法和分析指导。
