中国是一个具有五千多年历史的国家,两千多年的封建社会是中国历史的重要组成部分。在这两千多年中,天下分分合合,王朝在不断的被重建与毁灭中周期性更替。本文运用耗散结构的理论和方法,联系马克思主义唯物史观,分析了中国封建社会在朝代更替时的特点。认为在朝代更替时,社会必然处于混乱之中,即“大治之前必有大乱,大乱之后必有大治”。 China is a country with more than 5,000 years of history. The feudal society of 2,000 years is an important part of Chinese history. In these two thousand years, the world is divided and the dynasties are periodically replaced by continuous reconstruction and destruction. In this paper, the theory and method of dissipative structure are used in connection with the historical materialism of Marxism to analyze the characteristics of Chinese feudal society in the replacement of dynasties. That in the dynastic change, society must be in chaos, that is, “there must be chaos before the great rule, there must be a big rule after the chaos.”
