本研究考察了国际化经营背景下企业环境、社会和治理（ESG）活动的同伴效应。ESG同伴效应研究面临的核心挑战在于内生性问题，即企业的ESG活动与其同伴之间的互动可能受到共同因素的驱动。为缓解这一问题，本文利用海外东道国分批引入的强制性ESG信息披露法规作为外生冲击——该法规仅适用于东道国本土企业，而不适用于在同一市场运营的美国跨国企业（MNEs），从而为识别同伴效应提供了理想的准自然实验情境。以慈善捐赠作为企业ESG战略的关键维度，研究发现，东道国实施强制性ESG信息披露后，美国跨国企业与东道国企业在该国的捐赠数量均显著提高。进一步分析表明，这一结果与本土模仿性同构机制相一致，即跨国企业通过模仿东道国同伴的亲社会行为来获取当地经营合法性，以缓解外来者劣势（LOF）。本研究为ESG活动的同伴效应提供了跨国维度的新证据，同时为跨国企业海外ESG活动提供了新视角。

This study examines the peer effects of corporate Environmental, Social, and Governance (ESG) activities in the context of international business operations. A core challenge in studying ESG peer effects is endogeneity — firms' ESG activities and their interactions with peers may be jointly driven by common factors. To mitigate this concern, this paper leverages the staggered introduction of mandatory ESG disclosure regulations in foreign host countries as an exogenous shock. These regulations apply exclusively to local firms and not to U.S. multinational enterprises (MNEs) operating in the same market, thereby providing an ideal quasi-natural experimental setting for identifying peer effects. Focusing on philanthropic giving as a key dimension of firms' ESG strategies, the study finds that both U.S. MNEs and their local peers significantly increase their donation amount in the host country following the ESG mandate. Further analysis indicates that this finding is consistent with local mimetic isomorphism—MNEs imitate the prosocial behavior of their host-country peers to gain local operational legitimacy and mitigate the liability of foreignness (LOF). This study contributes new cross-national evidence on the peer effects of ESG activities, while also enriching the literature on MNEs' overseas ESG activities.
