国内对杨度的研究大多始于上世纪七十年代末期，这些研究多涉及杨度后期的政治主张与思想转变，而对杨度前半生的理论研究较为缺乏。在本文中，笔者以杨度东渡日本前的经历为框架，将杨度的前半生划分为数个阶段，对其各阶段的经历从经济、政治、思想等角度辅以史料分析，以概述其在清末社会变局下的早期生活经历。

Most of the studies on Yang Du in China began in the late 1970s, and most of these studies involved the political proposition and ideological change in the later period, while there is a lack of theoretical research on the first half of Yang Du's life. In this paper, the author takes the experience of Yang Du's journey to Japan as the framework, divides the first half of Yang Du's life into several stages, and analyzes the experience from the perspectives of economic, political and ideological materials, to summarize his early life experience under the social changes in the late Qing Dynasty.
