本文研究了企业层面的创新失败是否可以解释制造业生产率增长的跨国异质性。文献中没有强有力的证据证明存在这种联系。然而，我们的研究与以往使用企业层面数据对创新与生产率之间的关系进行的跨国比较有很多不同之处。首先，采用了创新投入的更广泛定义，其中研究和开发是创新的几个来源之一。第二，在分析中使用了定量的创新产出测度。第三，分析是基于更大和更有代表性的公司样本，包括小公司。最后，一个计量经济学框架的基础上的知识生产函数会计的选择性和选择性偏差。北欧国家的结果表明，由于在汇集数据方面存在困难，因此必须具体说明针对具体国家的模型，以说明各国的影响和各国国家创新体系的差异。
This paper investigates whether failure in innovation at the firm level can account for cross-country heterogeneity in manufacturing productivity growth. There is no strong evidence in the literature on the existence of such link. Our work, however, differs in a number of ways from much of the previous cross-country comparisons on the relationship between innovation and productivity using firm-level data. First, a broader definition of innovation input is used in which research and development is one of several sources of innovation. Second, a quantitative innovation output measure is used in the analysis. Third, the analysis is based on larger and more representative samples of firms including small firms. Finally, an econometric framework based on the knowledge production function accounting for both selectivity and simultaneity bias is employed. The results from Nordic countries show that given difficulties in pooling the data, it is important to specify country-specific models accounting for country-specific effects and differences in the countries national innovation systems.
