Cooperative relationships require trust. Trust, on the other hand, requires a framework, i.e. an environment, in which it can be built. Numerous studies have focused on the antecedents of trust. For example, various trust-building factors have been identified in these studies. However, there is no comprehensive study exploring the ways in which contracts support the trust-building environment. This study attempts to fill this gap by drawing on the notion that contracts have a framing effect on trust, thereby creating an environment that can lead to trust building. The study entails an analysis of eight contracts made between the Finnish Defence Forces and its civilian contractors. The analysis is theory-driven and applies a framework of trust-building factors. The conclusion of the study is that the contracts support the environment by defining roles and responsibilities, relevant legal regulation, communication processes, and forums for interaction. However, trust building would benefit if contracts were improved in five ways, namely by establishing fewer forums of communication, encompassing personal relations and potentially deviating interests, providing more communication via avenues other than key personnel, carefully considering the need for restrictive confidentiality clauses, and using contracts to pursue a certain culture.

合作关系需要信任。另一方面，信任需要可以建立信任的框架，即环境。许多研究集中在信任的前提上。例如，在这些研究中已经确定了各种建立信任的因素。但是，没有全面的研究探讨合同支持建立信任环境的方式。这项研究试图通过利用合同对信任具有框架效应的观念来填补这一空白，从而创造一种可以建立信任的环境。该研究需要分析芬兰国防军与其民用承包商之间的八份合同。该分析是理论驱动的，并应用了建立信任因素的框架。研究的结论是，合同通过定义角色和职责，相关的法律法规，沟通流程以及互动论坛来支持环境。但是，如果以五种方式改善合同，则建立信任将受益，即通过建立较少的交流论坛，涵盖人际关系和潜在的利益偏差，通过关键人员以外的途径提供更多的交流，仔细考虑对限制性保密条款的需要，以及使用合同追求某种文化。
