The literature review is an integral part of the research process, from developing research ideas to disseminating findings. It involves explaining, interpreting, and summarizing published materials around a topic to elaborate a research hypothesis/question, synthesize new concepts, identify knowledge gaps, develop new theories, and identify new research directions. Effective reading and processing of the literature (i.e., analyzing and synthesizing) and actual writing of the literature (verbal or non-verbal output, e.g., tables and figures) are essential stages of an effective literature review. This article provides a practical guide to conducting an effective literature review. In addition, literature search and evaluation are also briefly discussed.
文献综述是研究过程中不可或缺的一部分,从提出研究想法到传播研究结果。它包括解释、阐释和总结围绕某个主题发表的材料,以阐述研究假设/问题、综合新概念、识别知识空白、发展新理论以及确定新的研究方向。有效阅读和处理文献(即分析和综合)以及实际撰写文献(口头或非口头输出,如图表)是有效文献综述的关键阶段。本文提供了进行有效文献综述的实用指南。此外,还简要讨论了文献检索和评估。
