DEA's CCR Model for Evaluation of Urban Infrastructure Investment Efficiency of Shaanxi Province

Firstly, this paper uses DEA's CCR model to evaluate the relative efficiency of city infrastructure investment of 10 cities in Shaanxi province during 2008-2013. Then according to the panel data of city infrastructure input and output in 2008-2013, it has carried on the longitudinal comparison to observe the dynamic effect of infrastructure investment efficiency in the time series by using the Malmquist-DEA index method. Results show that the overall city infrastructure investment efficiency of Shaanxi province during the whole is on the rise; while each city development is not balanced, Xi'an development situation is relatively better; although, the Malmquist productivity index of the whole province infrastructure investment is restricted by the technical level, it is still on the rise.
