中文摘要
我们研究非上市企业的采购模式, 并考察这些在全球供应链中常被忽视却至关重要的参与者, 在预期需要为其组织边界之外的外部性承担责任时, 如何调整其采购来源。利用细粒度海关数据以及关于《德国供应链尽职调查法》的一次意外信息发布, 产品层面的回归显示, 进口企业从相关生产部门存在较高 ESG(环境、社会和治理)相关风险的国家采购某一产品的可能性要低 3.5 个百分点, 这表明企业倾向于切断与较高风险供应商的联系。该效应集中于对某一产品拥有高度多元化供应商网络且盈利能力较高的企业, 表明它们具备迅速应对预期监管压力所需的灵活性。我们的研究结果表明, 要求企业将广泛的可持续性考量纳入其经营决策的强制性规定可能存在局限, 尤其是对于非上市企业而言。
Abstract
We study the procurement patterns of non-listed firms and examine how these often-overlooked, yet pivotal players in global supply chains adjust their sourcing when they anticipate accountability for externalities beyond their organizational boundaries. Using granular customs data and a surprise information release about the German Supply Chain Due Diligence Act, product-level regressions reveal that importing firms are 3.5 percentage points less likely to source a product from countries where the relevant production sector exhibits elevated ESG-related risks, suggesting that firms tend to cut ties with higher-risk suppliers. The effects are concentrated among firms with well-diversified supplier networks for a product and higher profitability, suggesting they have the necessary flexibility to respond quickly to anticipated regulatory pressure. Our findings suggest that mandates requiring firms to incorporate broad sustainability considerations into their operational decisions may have limits, particularly for non-listed firms.
