Affected by complicated issues, such as regional conflicts, trade wars, and the COVID-19 pandemic, manufacturing firms face enormous challenges in reconstructing the global supply chain landscape to form new cooperative innovation mechanisms. This study investigates the relationship between supply chain partnerships (SCP) and innovation performance (IP) from a knowledge-management perspective. A multi-factor conceptual model of this relationship was proposed, considering the mediating effect of knowledge sharing (KS) and the moderating effect of knowledge distance (KD). SCP is measured in three dimensions: trust relationship (TR), commitment relationship (CMR), and contractual relationship (CTR). IP is measured in two aspects: technological innovation performance and management innovation performance. An empirical study was conducted to test the hypotheses using data from 417 valid questionnaires. Confirmatory factor analysis and structural equation modeling were applied to test the hypotheses. The results demonstrate that (1) KS plays a significant mediating role in how SCP impacts IP and that the indirect effect of TR through KS on IP is greater than that of CTR or CMR. (2) KD between supply chain partners plays a significant negative moderating role between KS and IP; that is, the smaller the KD, the higher the IP achievable through sufficient KS. These findings shed new light on building collaborative innovation mechanisms for supply chain management.

受地区冲突、贸易战、新冠肺炎疫情等复杂问题影响，制造企业在重构全球供应链格局、形成新的合作创新机制方面面临巨大挑战。本研究从知识管理的角度探讨了供应链伙伴关系（SCP）与创新绩效（IP）之间的关系。考虑知识共享（KS）的中介作用和知识距离（KD）的调节作用，提出了这种关系的多因素概念模型。SCP从三个维度来衡量：信任关系（TR）、承诺关系（CMR）和契约关系（CTR）。知识产权的衡量标准有两个方面：技术创新绩效和管理创新绩效。我们使用 417 份有效问卷的数据进行了一项实证研究来检验这些假设。应用验证性因素分析和结构方程模型来检验假设。结果表明：（1）KS 在 SCP 对 IP 的影响中起着显着的中介作用，并且 TR 通过 KS 对 IP 的间接影响大于 CTR 或 CMR。(2)供应链伙伴之间的KD在KS和IP之间起显着的负向调节作用; 也就是说，KD越小，通过足够的KS可以获得的IP越高。这些发现为构建供应链管理协同创新机制提供了新的思路。结果表明：（1）KS 在 SCP 对 IP 的影响中起着显着的中介作用，并且 TR 通过 KS 对 IP 的间接影响大于 CTR 或 CMR。(2)供应链伙伴之间的KD在KS和IP之间起显着的负向调节作用; 也就是说，KD越小，通过足够的KS可以获得的IP越高。这些发现为构建供应链管理协同创新机制提供了新的思路。结果表明：（1）KS 在 SCP 对 IP 的影响中起着显着的中介作用，并且 TR 通过 KS 对 IP 的间接影响大于 CTR 或 CMR。(2)供应链伙伴之间的KD在KS和IP之间起显着的负向调节作用; 也就是说，KD越小，通过足够的KS可以获得的IP越高。这些发现为构建供应链管理协同创新机制提供了新的思路。
