Legitimacy of economic activity by local public entity

政府合同是采购政策实施所需的商品和服务的手段，但往往拟议中的合同会被用作实现政策目标无关的手段。然而，为了使用这种合同，政府可能会提高采购价格。因此，是否允许使用政府合同作为政策手段是一个问题。契约自由不能成为正当理由，因为国家不享有契约自由。政府合同不是公共活动，而是公共活动。从这一点出发，可以支持将政府合同用作政策工具。另一方面，也提出了国家参与市场，以政府合同作为政策执行手段，可能会干扰正常的市场竞争。这两个要素之间的关系是要解决与国家经济关系。

Government contract is a means to procure goods and services needed for policy implementation, but often the proposed contract will be used as a means to achieve policy objectives unrelated. However, to use such contracts, the government may increase the procurement price. So if the use of government contracts as a means of policy is allowed or not, is the question. Freedom of contract cannot be justification, because the state does not enjoy the freedom of contract. The government contract is not a public activity, but a public activity. From that point, the use of government contracts as a policy instrument can be supported. On the other hand, it also raised the participation of state in market and the use of government contracts as a means of policy implementation could interfere with normal competitive market. Relationship between these two elements is to be resolved with the state-economy relations.
