This study develops a technology and social capital process aided product innovation conceptual model based on dynamic capability and supply chain ambidexterity theory. The strategy of organisational ambidexterity in balancing technological and relational social capital factors between buyers and suppliers leads to a higher level of digital manufacturing capabilities and enhances buyers’ innovation potential, considering the sustainable practices in their processes to cope with Industry 4.0 manufacturing processes and sustainability challenges. The study empirically validates the model using data collected from 379 French manufacturing companies. This is the first study that examines how buyers perceive the role of blockchain technology in exploring and exploiting innovation management in the Industry 4.0 era. The study advances understanding on the theory of ambidexterity of supply chains in buyer–supplier relationships. The study results show the positive effect between internal integration and blockchain technology as well as relational social capital factors in buyer–supplier relationships. The findings underscore the critical role of relational and technological capital in buyer–supplier relationships, specifically to act as a catalyst for exploiting internal capabilities to achieve the innovation targets. The unique findings state blockchain technology mediation is dominant in exploiting the internal capabilities and benefits buyers' innovation orientation.

本研究基于动态能力和供应链歧义理论，开发了一种技术和社会资本过程辅助的产品创新概念模型。考虑到采购商和供应商之间技术和关系社会资本因素之间平衡技术和关系性社会资本因素的组织战略，可以提高采购商的数字制造能力并增强其创新潜力，以应对其过程中的可持续实践以应对工业4.0制造流程和可持续性挑战。这项研究使用从379家法国制造公司收集的数据对模型进行了实证验证。这是第一项研究，旨在检验购买者如何看待区块链技术在工业4.0时代探索和利用创新管理中的作用。这项研究提高了对买卖双方关系中的供应链歧义性理论的理解。研究结果表明内部整合与区块链技术以及关系社会资本因素在买卖双方关系中的积极作用。研究结果强调了关系资本和技术资本在买卖双方关系中的关键作用，特别是充当了利用内部能力实现创新目标的催化剂。独特的发现表明，区块链技术的调解在开发内部功能方面占主导地位，并有利于买家的创新取向。研究结果表明内部整合与区块链技术以及关系社会资本因素在买卖双方关系中的积极作用。研究结果强调了关系资本和技术资本在买卖双方关系中的关键作用，特别是充当了利用内部能力实现创新目标的催化剂。独特的发现表明，区块链技术的调解在开发内部功能方面占主导地位，并有利于买家的创新取向。研究结果表明内部整合与区块链技术以及关系社会资本因素在买卖双方关系中的积极作用。研究结果强调了关系资本和技术资本在买卖双方关系中的关键作用，特别是充当了利用内部能力实现创新目标的催化剂。独特的发现表明，区块链技术的调解在开发内部功能方面占主导地位，并有利于买家的创新取向。
