Abstract This paper reports the results of a review and analysis we conducted on 416 empirical articles (EAs) published in the Journal of English for Academic Purposes (JEAP) over its lifespan (2002–2019). We present the results of the review and analysis across four broad themes, namely, (1) contexts and participants, (2) research foci and theoretical orientations, (3) research methodology and data sources, and (4) pedagogical implications. In addition to presenting the overall results, we also report findings across two periods (2002–2011 and 2012–2019). The typical article in JEAP was written by a single author addressing an instructional issue based on genre theory as related to undergraduates in universities and using combined methods (employing both quantitative and qualitative data and analysis). We present and discuss the findings overall, as well as across the two periods in relation to the four broad themes and their categories. Based on the findings, we make suggestions for future research in JEAP.

EAP 研究的背景、理论和方法方向：来自发表在学术英语杂志上的实证文章的证据

摘要 本文报告了我们对发表在学术英语杂志 (JEAP) 上的 416 篇实证文章 (EA) 在其生命周期 (2002-2019) 上进行的审查和分析的结果。我们展示了四个广泛主题的审查和分析结果，即（1）背景和参与者，（2）研究重点和理论方向，（3）研究方法和数据来源，以及（4）教学意义。除了呈现总体结果外，我们还报告了两个时期（2002-2011 和 2012-2019）的发现。JEAP 中的典型文章是由一位作者撰写的，针对与大学本科生相关的基于体裁理论的教学问题，并使用组合方法（采用定量和定性数据和分析）。我们总体上介绍和讨论调查结果，以及跨越两个时期的四大主题及其类别。基于这些发现，我们为 JEAP 的未来研究提出建议。
