Efficiency evaluation is helpful to find the problem in urbanization construction process and can provide reference to make scientific urbanization development strategy. This article carries on efficiency evaluation of urbanization construction in 31 county-level cities of Shandong Province based on the data envelope analysis (DEA) model. The results indicate that 20 cities are non-DEA effective, among which 7 cities are at the stage of increasing returns to scale and 13 cities are at the stage of decreasing returns to scale. The projection analysis of DEA model indicate that each input and output factor of non-DEA effective city has input redundancy and output insufficiency at different degree, and non-intensive degree of input factors is quite high, which shows that the present urbanization advancement is mainly pushed by extension growth of input factors.
