Despite significant improvements in transport, energy and information communication technology (ICT) infrastructures, inadequacies still exist in China's infrastructure development in light of emerging demand and industrial transition and upgrade. China lags far behind advanced economies such as the United States, Germany and Japan in terms of the quality of transport infrastructures except railroad," electricity infrastructure is insufficient and service efficiency needs improvement; ICT infrastructure requires all-round upgrade and gaps in Internet bandwidth are striking. This paper suggests that, based on the needs of supply-side structural reform, China must reform its investment and financing systems to enhance the efficiency of infrastructure investment. Efforts must be made to enhance air transport and port infrastructure to support industrial upgrade; to develop the energy Internet to address emerging demands; and to forge a new generation of ICT infrastructure with industrial Internet as the priority to prepare China for the new round of industrial competition. 展开更多
