Purpose: Recent research has focused on the impact of communication networks on the performance of construction project teams, attempting empirical exploration from various social network analysis perspectives. However, there is still a significant gap in understanding the variations in performance and the mechanisms for teams using different communication networks. Drawing from organizational learning theory and social network theory, this study, based on the Input-Mediator-Output (IMO) model, explores the effects of the interaction between centralization and tie strength in communication networks on team performance, as well as the mediating mechanisms of knowledge sharing behavior and team resilience performance in engineering project teams.
Methods: Drawing on classic group communication experiment, we design an online communication and collaboration platform to simulate the execution of a construction engineering project. Finally, data was collected through the communication experiment with 720 participants, and hypotheses were tested using ANOVA and PROCESS.
Results: The results indicate that under conditions of weak tie strength, centralized communication networks yield higher performance. Conversely, under conditions of strong tie strength, decentralized communication networks demonstrate superior performance. Furthermore, this study also verifies the mediating role of knowledge sharing behavior and team resilience performance when tie strength is strong.
Conclusion: This study focuses on engineering project team, exploring the evolutionary development of knowledge sharing behavior and team resilience performance from the perspective of the interaction of communication network structural characteristics, as well as the paths to enhancing team performance. Our research results highlight the interactive effects of structural indicators and relational indicators of communication networks, revealing the mechanism by which the structure of communication networks impacts team performance. Additionally, from the perspectives of forming and timely adjusting team communication models, and motivating and supporting employee communication behavior, our study provides practical insights for project managers and relevant administrators.

揭示通信网络对工程项目团队绩效的影响：集中化和联系强度的相互作用

目的：近期研究重点关注通信网络对建设项目团队绩效的影响，尝试从各种社交网络分析角度进行实证探索。然而，在理解使用不同通信网络的团队的性能差异和机制方面仍然存在很大差距。本研究借鉴组织学习理论和社会网络理论，基于输入-中介-输出（IMO）模型，探讨了沟通网络中的集权化与联系强度的相互作用对团队绩效的影响及其中介机制。工程项目团队中的知识共享行为和团队弹性绩效。
方法：借鉴经典的群体交流实验，设计一个在线交流协作平台来模拟建筑工程项目的执行。最后，通过 720 名参与者的交流实验收集数据，并使用 ANOVA 和PROCESS 测试假设。
结果：结果表明，在弱联系强度的条件下，集中式通信网络产生更高的性能。相反，在强联系强度的条件下，去中心化的通信网络表现出优越的性能。此外，本研究还验证了当关系强度较强时知识共享行为和团队复原力绩效的中介作用。
结论：本研究以工程项目团队为研究对象，从沟通网络结构特征交互的角度探讨知识共享行为与团队韧性绩效的演化发展，以及提升团队绩效的路径。我们的研究结果突出了沟通网络结构指标和关系指标的交互作用，揭示了沟通网络结构影响团队绩效的机制。此外，从形成并及时调整团队沟通模式、激励和支持员工沟通行为的角度，我们的研究为项目经理和相关管理者提供了实用的见解。
