Research on the Trust Cycle of the Contract Parties of Mega-projects Based on the Whole Process Perspective

Under the passive cooperation of contract constraint, the low management performance of large-scale projects has become the main problem in current engineering projects. The embedding of trust mechanism can effectively make up for the deficiency of contract governance and promote the sustainable development of the benign interaction and cooperation between the employer and the contractor. Based on the whole process of project practice, this paper analyzes the dynamic trust cycle between the contracting parties theoretically and practically. On this basis, with DIKA model as the intermediary, this paper expounds the evolutionary path of the leap of trust from the perspective of the whole process of the project, improves the level of trust between the contracting parties, reduces opportunistic behaviors, promotes the sustainable development of the cooperation between the two parties, and improves the performance of project management.
