学术界一般认为清初经世之学向考据学的演变主要是政治权力的外部压力所致，本文作者则认为，经世之学所以衰亡，更主要的原因是其内在的逻辑矛盾给外部侵袭留出了空隙。作者在考察了这一内在逻辑矛盾后认为，经世之学在本质上仍是为君权政治服务的儒家学术思想，这种思想在清政权尚未取得文化统治权力时还有相对独立的发展空间，而在清政权掌握了文化统治权力后，除了归附清政权或消亡外别无他途，因而经世之学的消亡是必然的。 It is generally believed by academics that the evolution of the study of Confucian classics in the early Qing Dynasty was mainly caused by the external pressure of political power. The author of this paper argues that the decline and decline of the classics classics is mainly due to its internal logical contradictions to external invasion Set aside the gap. After examining this internal logical contradiction, the author thinks that the study of the genesis of the world is still essentially a Confucian academic thought that serves the political sovereignty. This kind of thinking still has relatively independent space for development when the Qing regime has not obtained the power of cultural domination. After the Qing government took over the power of cultural reign, there was no alternative but to go to the Qing government or disappear, so the demise of the Confucian school was inevitable.
