Due to the increasing risk and uncertainty of construction projects, contractual flexibility has been considered as an effective tool to cope with emergences and to promote cooperation between owners and contractors. However, in practice, owners often failed to build an efficient cooperative relationship via contracts, resulting in a lacking of appropriate justice. Furthermore, due to a lack of available empirical research, the influence of contractual flexibility on the cooperative behavior of contractors requires further investigation. The purpose of this paper is to fill this gap by conducting empirical research from the perspective of justice perception.
A theoretical model was developed and a series of hypotheses were proposed. Then, partial least squares structural equation modeling analyses were conducted on a sample of 188 respondents.
The results show that contractual content and executing flexibility both have a positive influence on the cooperative behavior of a contractor, which was partially mediated by distribution, procedural, and interactional justice perceptions. Moreover, content flexibility has a significant impact on all three types of justice perception, and the execution of flexibility has more impact on interactional justice compared to other justice perceptions.
The findings contribute to an improved understanding of how contractual flexibility affects the cooperative behavior of contractors, indicating that the owner could develop a fair exchange relationship through flexible contracting and motivation of the other party.
