Responsibility boundaries and the governance of global value chains: The interplay of efficiency, ethical, and institutional pressures in global strategy
研究聚焦钽供应链，通过案例过程分析三家制造商面对效率、道德和制度压力时的不同战略回应，发现全球价值链的结构惯性要求企业通过战略重组而非维持结构来应对责任边界扩展。
Abstract Research Summary I explore the relationship of firm global strategy and global value chain (GVC) governance, within a context of expanding responsibility boundaries for unethical practices in the value chain. Specifically, focusing on the tantalum supply chain within the digital electronics GVC, I conduct a case‐based process study that contextualizes the different strategic responses of three manufacturers of tantalum capacitors when faced with similar efficiency, ethical, and institutional pressures. Integrating the GVC and global strategy literatures, I find that structural inertia in GVCs limits the efficacy of strategies that preserve, rather than alter, the governance structure, instead requiring a strategic restructuring carried out by individual firms, whose internalization of responsibility boundaries is encouraged by the institutionalization of these boundaries through public policy. Managerial Summary Unethical practices within global value chains are increasingly becoming the responsibility of firms with no direct control over such practices, leading to growing pressures for firms to alter their global strategies to meet social and institutional demands. Research has focused on strategies that preserve the structure of the value chain, despite questions about the efficacy of these approaches. By looking at the case of “conflict minerals” within the digital electronics value chain, this study finds that inherent flaws in value chain structures, which managers can identify, require individual firms to implement strategies that change the structure of the value chain, specifically by increasing ownership and control over the linkages where unethical practices occur and encouraging public policies that add value to these strategies.
