Liang Qichao 梁启超 was a pioneer thinker to engage in theoretical thinking and interpretation of the aggression of the foreign powers since the First Opium War. His theory of tangible partition and intangible partition provided a deep analysis of the ways and means of foreign aggression against China， concluding that the intangible was more devastating than the tangible，touching upon the essential characteristics of the imperialist colonial expansion. Subsequently， with the popularity of imperialism theory in the political and academic circles of Europe， America and Japan， Liang not only imported it into China， but also provided theoretical interpretations. In contrast to the western theory of imperialism which aimed to defend the colonial aggression of the foreign powers， Liang’s theory of imperialism was on the standpoint of the Chinese nation. While drawing on the relevant concepts of the Western theories of imperialism， Liang rejected any attempts to justify or glorify imperialist aggression， fully alerting and revealing the aggressive nature of imperialism， particularly emphasizing the harm of economic imperialism to China. which showed an inherent ideological continuity with his theory of “tangible or intangible partition”. Liang’s cognition of the overall trend， means， and characteristics of imperialist aggression and expansion， as well as his explanation of China’s response strategies， constituted the basic discourse of how the Chinese intellectual community analyze the international situation and solve China’s problems during this period， exerting a far-reaching impact on the public opinion at that time.
