Aiming at the problem of inefficiency of infrastructure investment in the process of China's urbanization, on the basis of summarizing forefather's research results, this paper analyzed the efficiency of input and output of infrastructure investment of China's provinces in 2005-2012 using Super-efficiency DEA model and Malmquist index under the background of new-type urbanization.
