澳門是孫中山睜眼望洋、走向世界的門戶，也是他早期從事社會活動和革命活動的基地。在澳門的生活經歷以及見證澳門主權問題的社會閱歷，不僅為他早期改良主義性質的思想觀念提供了養分，亦為他逐步走向近代資產階級革命道路，並建構一套以三民主義為核心的法政思想體系奠定了基礎。考察澳門印痕實際是重新追溯孫中山法政思想的發展歷程，有助於我們更深入地理解其思想體系賴以建構成型的特定時空背景。

Macau was a window for Mr. Sun Yat-Sen in reaching out to the world, and was also a base for his early social and revolutionary activities. The experience gained when living in Macau and his witnessing to the question on the sovereignty of Macau provided stimulus for him to develop a reformist thought, as well as the foundation for him to commit to the course of modern bourgeoisie revolution and to develop his judicial and political ideological system with the Three Principles of the People as the core. An investigation on his impressions of Macau is in fact an exercise to trace the course of development of Sun Yat-Sen’s judicial and political thoughts, which will help us to understand more profoundly the context of such formation.
