How much does the host country matter in explaining foreign affiliate performance? Using a global sample of 34,708 foreign affiliates operating in 91 host countries, we revisit the relative importance of the host country effect as a performance determinant. Our variance decomposition results suggest that the host country effect is less salient than previously identified, often explaining a small portion of affiliate performance differences. We offer implications for future international strategy research on foreign affiliate performance, advancing an understanding of the relative importance of external and internal determinants. We direct scholarly attention to other effect classes, namely the affiliate effect.

东道国在解释外国子公司业绩方面有多重要？使用在 91 个东道国运营的 34,708 家外国子公司的全球样本，我们重新审视了东道国效应作为绩效决定因素的相对重要性。我们的方差分解结果表明，东道国效应没有以前确定的那么显着，通常可以解释一小部分联属网络营销绩效差异。我们为未来关于外国子公司绩效的国际战略研究提供了启示，促进了对外部和内部决定因素的相对重要性的理解。我们将学术注意力引向其他效应类别，即关联效应。
