Abstract: The urban efficiency and its changes in Jiangsu province were analyzed based on relevant panel data from 13 prefecture-level cities in Jiangsu province from 2006 to 2015 using the DEA model and the Malmquist index. From the static analysis results of urban technical efficiency in Jiangsu province in 2015, the technical efficiency of cities in Jiangsu province is generally high, but most prefecture-level cities still have not realized the effective allocation of resources. According to the annual Malmquist productivity index and decomposition results in the decade of 2006—2015, the advancement of technology level is crucial for the improvement of urban productivity in Jiangsu province. Therefore, in the process of promoting urban development, Jiangsu province needs to focus on improving the technological level, and rationally allocate the resources of production factors to improve that efficiency of the city.
