Abstract: Upon the proposal of the development strategy of “Internet+” at the National People's Congress and the Chinese Political Consultative Conference(NPC & CPPCC)in 2015, the development of E-commerce has been paid full attention to by local governments of all levels. The E-commerce development level in counties of Fujian ranks only second to that in Zhejiang. In order to deeply understand the E-commerce development situation and its experience in advantageous counties in Fujian, an investigation of 100 best Alibaba e-commerce counties, the top 100 Jingdong E-commerce counties and the first batch of E-commerce demonstration counties in Fujian was carried out. The result shows that a large majority of E-commerce advantageous counties in Fujian have based their development on the local industry foundations, while achievements made in Zhenghe County in terms of E-commerce indicate that even the relatively backward mountainous counties can achieve local economic development and upgrade their local industries by virtue of E-commerce, thus to make the “on-the-curve overtaking” a reality. Key words: Fujian Province; E-commerce index; electronic commerce
