古史分期问题在经过一段时间的沉寂之后,近年来又趋于活跃,在最近几年的研究中,一个显著特点是“五种生产方式说”遭到怀疑,否定奴隶时代在中国上古时期的存在,成为一些史家的共识。研究越深入,需要澄清和亟待解决的问题就越多。纵观近些年的研究,可以看出,史学工作者们只要遵循实事求是的原则,每每从一个新角度着手探讨古史问题,均能窥探到我国古代社会独特面貌的一个部分。因此,辨析越多,越能促进人们做更深入。更细致的思考,从而愈益能够显现中国古代社会的特性。目前,这一研究方兴未艾、但它的发展趋势即可以大慨作出如下勾勒,那就是史学工作者日益抛弃从概念到概念的、生搬硬套的、公式化的陈旧研究方法,立足于历史实际、力求从更深的层次上揭示我国古史的真实面貌。晁福林先生近著《夏商西周的社会变迁》（北京师范大学出版社1996年出版,以下引用此书简称《变迁》）一书,便是在前人研究基础上,对于复商周三代社会性质和古史分期问题的新探讨,从正面回答了上古时代——特别是夏、商、西周时代的社会性质问题。 After a period of silence, the issue of staging of ancient history has become more and more active in recent years. In the studies of recent years, one of the notable features is the suspicion of the “five modes of production” and the denial of the era of slavery in ancient China Existence, as some historians consensus. The more in-depth research, the more problems need to be clarified and solved urgently. Looking at recent years, we can see that whenever historians follow the principle of seeking truth from facts, they often start to probe into the issue of ancient history from a new angle and can all see one part of the unique face of ancient China. Therefore, the more discrimination, the more we can promote people to do more. More detailed thinking, which can increasingly show the characteristics of ancient Chinese society. At present, this research is in the ascendant. However, its development trend can be broadly outlined as follows. Historiographers are increasingly abandoning stereotyped and formulated old research methods from concept to concept. Based on historical fact, they strive to move from deeper to deeper Level reveals the true face of ancient Chinese history. In his book The Social Changes in the Xia, Shang and Western Regions (published by Beijing Normal University Press in 1996, the following is a reference to this book, “Change”), Mr. Chao Fulin, on the basis of previous studies, A new exploration of the issue of the staging of ancient history answers the question of social nature in the ancient times, especially in the Xia, Shang and Western Zhou Dynasties.
