摘要：
Water conservancy construction is an important infrastructure related to national economic and social development, and effective water conservancy investment is the premise guarantee for water conservancy reform. Therefore, it is necessary to study the efficiency of water conservancy investment. The efficiency of water conservancy investment in Shaanxi Province is evaluated by the super-efficiency DEA model and the Malmquist index.The results show that the comprehensive efficiency of water conservancy investment in most regions of Shaanxi Province increased steadily from 2012 to 2017, and pure technical efficiency is the main reason that hinders the further improvement of the efficiency of water investment in various regions. Therefore, it is necessary to strengthen technological innovation, optimize organizational structure, continuously adopt advanced technology, and expand the scale of water conservancy construction in order to attain the maximum value of investment.
