Abstract:

【Purpose/significance】 EPC projects are often promoted by multi-type subjects with multiple goals and heterogeneous

workflows, which shows the organizational characteristics of knowledge-chain. In-depth study of the interface synergy mechanism of

knowledge transfer between organizations can effectively open up the knowledge chain and promote the transfer and sharing of core

knowledge of EPC projects, and fully stimulate the potential advantages of various project participants, thereby maximizing project per⁃

formance

.

【Method/process】 In this paper, the background and main subjects of EPC project knowledge chain are defined firstly, and

the characteristics of EPC project knowledge are deeply analyzed, followed by the clarifying of project knowledge transfer path among

knowledge chain organizations. The characteristics of knowledge chain organization interface and its obstacles to knowledge transfer

are studied, thereby the interface synergy mechanism and model of EPC project knowledge chain organization being constructed.【Re⁃

sult/conclusion】In order to improve the efficiency of knowledge transfer between knowledge chain organizations and maximize the per⁃

formance of EPC project, it is necessary to effectively overcome the problem of knowledge interface barriers. The results shows that the

explicit interface synergy mechanism of information technology can reduce the complexity and explicit knowledge interface barriers,

and the implicit and potential knowledge interface barriers can be reduced by the implicit interface synergy mechanism of relationship

connection. Thus, the efficiency of knowledge transfer among knowledge chain organizations can be improved in an all-round way.【In⁃

novation/limitation】 In this paper, the overall path and inner mechanism of knowledge transfer between EPC project knowledge chain

organizations are clarified from the view of overcoming interface barriers, and the implicit and potential knowledge interface synergy

mechanisms are therefore put forward. The limitation of this study is that no actual case data is introduced to carry out empirical re⁃

search, which can be further supplemented using the method of SEM in the future.
