中文摘要：

长三角作为改革开放的前沿地区，技术进步对经济增长贡献轨迹具有独特性。原始积累始于城市边际技术转移，其后转化为技术装备全线引进，推动技术进步内生化。实证分析证实了相关思想：上海和江苏上述路径较为完整，技术进步内生化程度较高；浙江的前两步相对欠缺，内生化程度较低造成后续发展过程中技术进步的贡献率也最低。

英文摘要：

The contribution of technological advances to the paths of economy growth in Yangtze Delta, the frontier of reforming and opening, has specific characteristics. Original capital accumulation begins from city marginal technological transfer, and then the full-set technological equipment brings about from foreign prompted technological advance endogenous. Positive analysis proves the following ideas： such paths are more complete in Shanghai and Jiangsu, and their technological advance endogenous is better. Whereas the first two-steps in Zhejiang are incomplete, and the technological advance endogenous is worse, which makes the contribution to the growth is the lowest in later development.
