In this paper, we describe and develop a two-step model, based on the CDM approach and the new firm paradigm, to link innovation outputs and ICT to productivity gains, using micro-level data from 1,000 Polish companies. Our study confirmed the mediating role of innovations and ICT complementarities with respect to productivity gains. However, the main finding is that the strength of this relationship depends on the company's distance to the technological frontier. We show that the more productive a company is, the more important are co-innovative sources of productivity. Thus, support programmes should also be provided to highly productive companies, which require a higher level of ICT complementarities to boost productivity. This finding may hold true for other CEE countries as well.

波兰的创新，ICT和ICT驱动的劳动生产率

在本文中，我们描述并开发了一个基于CDM方法和新公司范例的两步模型，该模型使用来自1000家波兰公司的微观数据将创新产出和ICT与生产率提高联系起来。我们的研究证实了创新和ICT互补性在提高生产率方面的中介作用。但是，主要发现是这种关系的强度取决于公司与技术前沿的距离。我们表明，公司的生产率越高，协同创新的生产力来源就越重要。因此，还应向高生产率的公司提供支持计划，这些公司需要更高水平的ICT互补性以提高生产率。这一发现也可能适用于其他中东欧国家。
