Abstract: This paper constructs a comprehensive environmental pollution index to reflect the undesired output of environmental pollution through. Based on the non radial and non angle DEA—SBM efficiency measurement model with the undesirable outputs, it measures the industrial environmental technical efficiency of 30 provinces in China from 2001 to 2015.Then it uses the Dagum Gini coefficient and its subgroup decomposition method, the kernel density estimation and spatial Markov chain to analysis the regional disparities and dynamic evolution of China's industrial environmental technical efficiency under the constraints of resource and environment. The results show that: first, China's industrial environment technical efficiency has agglomeration characteristics under the constraint of resource and environment and the distribution pattern of disparities space in east high west is presented. At the same time, the environmental technical efficiency in China is increasing and the distribution state of polarization is obvious; second, the regional disparities of industrial environmental technical efficiency in China have been expanding, the interregional disparities and intensity of transvariation are the main source of the hole regional disparities; third, The evolution of industrial environmental technical efficiency distribution in China is generally influenced by the lag type of the neighborhood space，but in the traditional mode of extensive industrial development, China's industrial environmental technical efficiency has a strong path dependence, so it is difficult to achieve short span development in 1 years. Finally，based on the empirical results, it put forward some advice accordingly.
