Public procurement has been studied by numerous researchers and is considered to be an effective instrument for leading public and private actors to implement more sustainable practices. For researchers, public procurement can be leveraged to develop innovative practices oriented towards sustainability and create new markets for eco-friendly products. However, there is still a paucity of empirical evidence on the mechanisms by which public procurement can effectively stimulate sustainable innovation and foster the development of greener markets in relation to circular economy. To shed light on the emerging issue of circular public procurement, we use a qualitative method relying on an empirical case relating to a public tender in Denmark. Our research shows that public procurement can be studied as a design activity and clarifies the mechanisms by which public procurement can stimulate sustainable innovation in organizations, creating opportunities for collective innovative practices. Furthermore, we shed light on the process through which circular public procurement can create green markets, defining the qualities of the goods to be exchanged.

许多研究人员已经研究了公共采购，它被认为是领导公共和私人行为者实施更可持续实践的有效工具。对于研究人员而言，可以利用公共采购来开发面向可持续性的创新做法，并为环保产品创造新的市场。但是，关于公共采购可以有效刺激可持续创新并促进与循环经济相关的绿色市场发展的机制，仍然缺乏经验证据。为了阐明新出现的循环公共采购问题，我们使用定性方法，其依据是与丹麦公开招标有关的经验案例。我们的研究表明，公共采购可以作为一种设计活动进行研究，并阐明了公共采购可以刺激组织中的可持续创新，为集体创新实践创造机会的机制。此外，我们阐明了循环公共采购可以创造绿色市场，定义待交换商品质量的过程。
