In this essay a quantitative empirical study with additional qualitative studies are performed. The purpose of this essay is to study how public procurement is used as a political instrument through the national procurement strategy. Swedish procurement legislation is based on EU directives since January 1, 1994 when the 1992 Act: 1,528 entered into force. The purpose of the provisions was to ensure legal certainty in the purchasing and commercial practices of public authorities. Public authorities spend about 17% of EU gross domestic product on public procurement. The value of purchases covered by procurement laws is estimated at approximately SEK 625 billion, which corresponds to 25% of GDP excluding VAT. This represents just over one-sixth of gross domestic product. Swedish procurement law is based on EU law and lies between administrative and civil law and is often described as commercial administrative law, as public procurement concerns how the public sector will act in commercial transactions. Public procurement has in recent years been the subject of political focus and a way to achieve political goals. The conclusions of this essay are that it is mainly time and human resources that causes a deficient implementation of the national procurement strategy. According to the top-down perspective, there are a number of possible obstacles to the implementation of a policy, lack of time and resources in the state authorities may have contributed to the national procurement strategy not being implemented to the extent that the government probably hoped. The national procurement strategy has had a direct effect on 5 authorities regarding social sustainability. The authorities that have given social sustainability their own heading in the governing documents can, from the top-down perspective, be considered to have had sufficient time to implement the concepts.
