Although food loss and waste (FL&W) is high on China's national policy agenda, there is still little scientific information published about how much FL&W exists in China, what its impacts are, and what needs to be done to reduce it. Furthermore, what is known about FL&W across the various hotspots of China's food supply chain is not accessible in one place due to the tendency of scholars to focus on one part of the food chain depending on their disciplinary backgrounds, thereby making it difficult to obtain a 'comprehensive whole supply chain perspective'. Thus, this review provides an interdisciplinary collation of what is already known about FL&W in China. A systematic review of both English and Chinese databases followed PRISMA guidelines further complemented with a qualitative content analysis process uncovered 57 articles. The view revealed confounding factors such as an inconsistency of the definitions and calculation methods used to measure FL&W, and research gaps such as a lack of focus on the behavioral factors pertaining to waste, and the limited range of social innovations studied to reduce it. Thus, this review will help in the development of research agendas designed to advance efforts in this field.
尽管食物损失和浪费（FL＆W）在中国的国家政策议程中占据重要地位，但有关中国存在多少 FL＆W、其影响是什么以及需要采取什么措施来减少 FL＆W 的科学信息仍然很少。此外，由于学者们根据自己的学科背景专注于食物链的某一部分，因此对于中国食品供应链各个热点地区的 FL＆W 了解情况无法集中在一个地方，这使得很难获得“全面的整个供应链视角”。因此，本综述提供了对中国已经了解的 FL＆W 的跨学科整理。对英文和中文数据库进行系统审查，遵循 PRISMA 指南，并进一步辅以定性内容分析过程，共发现 57 篇文章。该观点揭示了一些混淆因素，例如用于衡量 FL＆W 的定义和计算方法不一致，以及研究空白，例如缺乏对与浪费有关的行为因素的关注，以及研究范围有限的社会创新来减少 FL＆W。因此，本综述将有助于制定研究议程，以推动该领域的工作。
