面对全球化竞争和市场需求快速变化的挑战，本研究聚焦于供应链管理中知识共享的关键影响因素及其对企业绩效的影响。通过提出物流服务供应链知识共享主体维度及相关情境和测量因素的调节效应假设，并进行元分析实证研究，包括发表偏移检验、异质性检验、效应性检验及敏感性分析，验证了研究结果的稳健性。研究发现，知识内容的深度与广度、合作主体的参与度、国家文化和经济环境等情境因素，以及取样地区和企业绩效测量方式等测量因素显著影响供应链知识共享的合作策略和效果。特别是供应商的积极参与和特定文化背景下企业的表现更为突出。这些因素通过促进信息流通、增强成员之间的信任与合作、提高供应链的灵活性和响应能力来提升企业绩效。基于元分析结论，本研究提出了优化企业间知识共享合作效果的具体管理措施和实践指导，为公司在供应链中有效开展知识共享活动提供了明确的建议。Facing the challenges of global competition and rapid changes in market demand, this study focuses on the key influencing factors of knowledge sharing in supply chain management and its impact on enterprise performance. By proposing the moderating effect hypothesis of the main dimension of knowledge sharing in logistics service supply chain and related scenarios and measurement factors, and conducting meta-analysis empirical research, including publication bias test, heterogeneity test, effectiveness test and sensitivity analysis, the robustness of the research results is verified. The research found that the depth and breadth of knowledge content, the participation of cooperation subjects, national culture and economic environment and other situational factors, as well as the sampling area and enterprise performance measurement methods and other measurement factors, significantly affected the cooperation strategy and effect of supply chain knowledge sharing. In particular, the active participation of suppliers and the performance of enterprises under the specific cultural background are more prominent. These factors promote enterprise performance by promoting information flow, enhancing trust and cooperation among members, and improving supply chain flexibility and responsiveness. Based on the conclusion of meta-analysis, this study puts forward specific management measures and practical guidance to optimize the effect of knowledge sharing cooperation among enterprises, and provides clear suggestions for companies to effectively carry out knowledge sharing activities in the supply chain.
