中国早期马克思主义者在接受马克思主义学理的过程中，在很大程度上都曾受到其自身既有知识结构和所处时代问题的影响，相应地，这种影响又会使他们对马克思主义的解释形成一种不同于经典文本的中国表达。作为中共创始人之一的李大钊，也同样经历过这一思想历程，并在同时代人中具有典型性。李大钊思想中的民本主义及其所派生的大众观念、民族主义和社会责任意识等，在其接受和解释马克思主义过程中究竟产生过何种影响？它们之间如何会通？对这些问题的进一步分析与讨论，有助于更深一层地理解五四前后李大钊的思想转变和马克思主义在中国具体传播的思想起点。

In the process of accepting Marxism, the early Chinese Marxists were greatly influenced by their own knowledge structure and the problems of the times. Correspondingly, this kind of influence made their interpretation of Marxism form a kind of Chinese expression differing from the classic texts of Marxism. As one of the founders of the Chinese Communist Party, LI Da-zhao typically went through such a process. What was the impact of LI Da-zhao's people-oriented consciousness, as well as its derived ideas such as populism, nationalism and social responsibility, on his acceptance and interpretation of Marxism? How do they interact with each other? Further analysis and discussion of these issues will be conducive to a deeper understanding of LI Da-zhao's intellectual transformation before and after the May 4^th Movement and the concrete ideological starting point of the spread of Marxism in China.
