Study on the Evaluation of Technological Innovation Efficiency of Equipment Manufacturing Industry in China Based on Improved DEA

摘要

This paper uses a panel data of statistical panel data over the period 2007-2009, and applies the DEA method to evaluate the efficiency of the equipment manufacturing industry technology innovation in China, by using the improved DEA to evaluate 7 kinds of equipment manufacturing industry technology innovation efficiency, and has achieved the differentiation and sorting of various sub-sector by using the improved DEA model, which solve the problem that when the number of DMU is too small, the DMU can't be ranked. The Empirical result shows that the major categories of equipment manufacturing industry, technological innovation efficiency is generally low. The evaluation results can provide not only a new evaluation method for less decision unit, but also a new idea for the DEA evaluation theory and application.
