Requirements Engineering (RE) requires the collaboration of various roles in SE, such as requirements engineers, stakeholders and other developers, and it is thus a highly human dependent process in software engineering (SE). Identifying how human aspects such as personality, motivation, emotions, communication, gender, culture and geographic distribution might impact RE would assist us in better supporting successful RE. The main objective of this paper is to systematically review primary studies that have investigated the effects of various human aspects on RE. A systematic literature review (SLR) was conducted and identified 474 initial primary research studies. These were eventually filtered down to 74 relevant, high-quality primary studies. Among the studies, the effects of communication have been considered in many RE studies. Other human aspects such as personality, motivation and gender have mainly been investigated to date related to SE studies including RE as one phase. Findings show that studying more than one human aspect together is beneficial, as this reveals relationships between various human aspects and how they together impact the RE process. However, the majority of these studied combinations of human aspects are unique. From 56.8% of studies that identified the effects of human aspects on RE, 40.5% identified the positive impact, 30.9% negative, 26.2% identified both impacts whereas 2.3% mentioned that there was no impact. This implies that a variety of human aspects positively or negatively affects the RE process and a well-defined theoretical analysis on the effects of different human aspects on RE remains to be defined and practically evaluated. Findings of this SLR help researchers who are investigating the impact of various human aspects on RE by identifying well-studied research areas, and highlight new areas that should be focused on in future research.

人为因素对需求工程过程的影响：系统文献综述

需求工程 (RE) 需要 SE 中各种角色的协作，例如需求工程师、利益相关者和其他开发人员，因此它是软件工程 (SE) 中高度依赖于人的过程。确定人格、动机、情感、沟通、性别、文化和地理分布等人为因素如何影响可再生能源将有助于我们更好地支持成功的可再生能源。本文的主要目的是系统地回顾主要研究，这些研究调查了人类各个方面对 RE 的影响。进行了系统文献回顾 (SLR) 并确定了 474 项初步初级研究。这些最终被过滤到 74 项相关的、高质量的初级研究。在这些研究中，许多可再生能源研究都考虑了沟通的影响。迄今为止，其他人的方面，如个性、动机和性别，主要与 SE 研究相关，包括作为一个阶段的 RE。研究结果表明，一起研究不止一个人的方面是有益的，因为这揭示了人的各个方面之间的关系以及它们如何共同影响 RE 过程。然而，这些研究的人类方面的组合中的大多数都是独一无二的。56.8% 的研究确定了人类方面对 RE 的影响，40.5% 确定了积极影响，30.9% 确定了负面影响，26.2% 确定了两种影响，而 2.3% 提到没有影响。这意味着各种人的方面对可再生能源过程产生积极或消极的影响，关于不同人为方面对可再生能源的影响的明确理论分析仍有待定义和实际评估。
