A new-round technical and industrial revolution is emerging represented by information technology, which is a strong drive for the economic and social development. Meanwhile, Internet development has given rise to new challenges to all countries’ sovereignty, security, and interests. It is the common goal and vision of the international community to promote the sustaining development of the Internet so that all nations can share the Internet development achievements. The goal requires joint effort and participation of all countries. Against this backdrop, we decided to compile the World Internet Development Report 2017 (“the Report” for short hereinafter) to study and analyze the world Internet development, summarize the past experience, analyze the present status, and manifest the Chinese academic circles’ knowledge and thinking of the world Internet development, providing new reference and intelligent support for the global Internet development.
