Analysis on Industrial Land Efficiency of Central Yunnan Economic Zone Based on Big-Dat

To speed up the industrial transformation, promote enterprise technology improvement and improve the efficiency of industrial of industry, This study use of DEA and Malmquist Index model decomposition method, comparative analysis of the 2006-2011 period under the background of big data, the differences in four cities in Central and industrial land in the process of change in total factor productivity in the rapid urbanization. The results prove that: 1. Yunnan urban industrial land productivity are quite different. Difference between the productivity of industrial land in Central. 2. Returns to scale urban industrial land in Central region are showing a decreasing trend. 3. Yunnan urban industrial TFP index most decline. Therefore, accelerating industrial restructuring and upgrading, investments in technology, and promoting technical improvements are realized the only way to enhance the efficiency of industrial land.
