[Abstract] In this paper, we look again at the status, connotations, effects, and prospect of current broadband. We suggest that a) broadband can be the critical infrastructure for economic and social development and can provide a solid backing for national sovereignty and security in network cyberspace; b) it improves economic productivity and efficiency and can boost GDP; and c) it is the basic technology for future sustainable development goals. Broadband construction in China needs more investment, and government policies.
