Public sector procurement is increasingly seen as an important instrument for inducing innovation in the private sector. Yet, a broad range of different concepts, each with their own associated rationales, and approaches, are used in literature and practice to describe the stimulation of innovation through public procurement. Due to a lack of an overview on the use of concepts, rationales and approaches to stimulate innovation through public procurement in literature and practice, it remains difficult for public organisations to decide why, how, and to what extent they will stimulate innovation in the private sector through public procurement. The contributions of this article to mitigate this problem are threefold. First, it provides a review of the different streams of literature, dichotomies and typologies on public procurement with respect to inducing innovation. Second, it discusses various approaches to stimulate innovation through public procurement individually and compares them in a structured overview. Finally, it provides guidance on the suitability of the use of these approaches in different situations.

公共部门采购越来越被视为促进私营部门创新的重要工具。然而，在文献和实践中使用了范围广泛的不同概念，每个概念都有自己的相关原理和方法，以描述通过公共采购刺激创新。由于在文献和实践中缺乏对通过公共采购刺激创新的概念、原理和方法的使用的概述，公共组织仍然难以决定它们为何、如何以及在多大程度上刺激私营部门的创新通过公共采购部门。本文对缓解此问题的贡献有三方面。首先，它提供了对不同文学流派的回顾，公共采购在引导创新方面的二分法和类型学。其次，它分别讨论了通过公共采购刺激创新的各种方法，并在结构化概述中对它们进行了比较。最后，它就在不同情况下使用这些方法的适用性提供了指导。
