公司的创新绩效已经得到相当广泛和长期的研究。然而，许多研究的结果尚未形成一个普遍接受的创新绩效指标或一套通用的指标。到目前为止，在结构、测量、样本、行业和国家方面的多样性已经很大。本文使用多种指标，研究了四个高科技行业近 1200 家公司的大型国际样本的创新绩效。这些指标涵盖从研发投入、专利数量、专利引用到新产品发布等。该研究表明，基于这四个指标的复合结构清楚地捕捉到了潜在变量“创新绩效”。然而，我们的研究结果还表明，这些指标之间的统计重叠非常严重，未来的研究也可能会考虑使用这些指标中的任何一个来衡量高科技行业公司的创新绩效。 (C) 2002 Elsevier Science B.V. 保留所有权利。
The innovative performance of companies has been studied quite extensively and for a long period of time. However, the results of many studies have not yet led to a generally accepted indicator of innovative performance or a common set of indicators. So far the variety in terms of constructs, measurements, samples, industries and countries has been substantial. This paper studies the innovative performance of a large international sample of nearly 1200 companies in four high-tech industries, using a variety of indicators. These indicators range from R&D inputs, patent counts and patent citations to new product announcements. The study establishes that a composite construct based on these four indicators clearly catches a latent variable 'innovative performance'. However, our findings also suggest that the statistical overlap between these indicators is that strong that future research might also consider using any of these indicators to measure the innovative performance of companies in high-tech industries.
