Research on academic expatriation has rarely investigated the drivers of academic performance in a foreign cultural environment. This study focuses on research productivity as a crucial facet of performance and integral part of academic jobs. Drawing from the job demands-resources model, we position perceived organizational support and the number of doctoral students supervised as resources and teaching and service load as demands of self-initiated expatriate (SIE) academics' jobs. Most importantly, we suggest that being cross-culturally adjusted is a vital personal resource living and working in a foreign country and that cross-cultural adjustment moderates the effects of demands and resources. The analysis of combined survey and publication data from 208 SIE academics in natural sciences indicates that the number of doctoral students supervised increases research productivity, while teaching load reduces it. Moreover, findings show that cross-cultural adjustment amplifies the effects of demands and resources. The implications of these findings are discussed.

自发的外籍学者的研究生产力：工作需求、资源和跨文化调整的影响

关于学术外派的研究很少调查外国文化环境中学术表现的驱动因素。本研究侧重于将研究生产力作为绩效的关键方面和学术工作的组成部分。借鉴工作需求-资源模型，我们将感知的组织支持和监督的博士生数量定位为资源，并将教学和服务负荷定位为自发外派（SIE）学者的工作需求。最重要的是，我们认为跨文化适应是在国外生活和工作的重要个人资源，跨文化适应调节需求和资源的影响。对 208 位自然科学领域 SIE 学者的综合调查和发表数据的分析表明，指导的博士生人数提高了研究生产力，而教学负担降低了。此外，研究结果表明，跨文化调整放大了需求和资源的影响。讨论了这些发现的含义。
