Given insufficient efficiency areas of industrial park land in China,we selected 16 state-level industrial parks in the Yangtze River delta urban agglomeration. Based on the input and output unit land area index,VRS-DEA modeling and the Malmquist index,we decompose the dynamic evaluation of land use efficiency,and analyze the input and output factors of improving potential. We found that from 2010-2014,the Yangtze River delta urban agglomerations industrial park comprehensive efficiency of land use was an average of 0.600. Only two industrial parks are efficient,and the efficiency differences between land use regions is obvious. In the view of changes in efficiency decomposition,changes in the scale efficiency of land use are the main cause resulting in the evolution of technical efficiency. From a dynamic time series,the Malmquist productivity index was driven by technical efficiency change and grew over the five years. Weakness in technical improvements is the core element of land use efficiency. Through the analysis of land use non-DEA efficient urban spaces,industrial parks have common output redundancy including tax revenues and industrial production. While maintaining investment scale effectiveness,improving the technical efficiency of industry,investment promotion and the tax system is a realistic path to improve land use efficiency of industrial parks in Yangtze River Urban Agglomerations.
