Based on the characteristics of small and micro technological enterprises and known achievement in scientific research,the evaluation index system of financing efficiency was set up,taking enterprise's total assets,main business cost and asset-liability ratio as inputs,and return on net assets,growth rate of main business income and total assets turnover ratio as outputs.The data envelopment analysis (DEA) models,capable of deleting environmental effect and statistical noise,were established to study the financing efficiency of 54 registered small and micro technological enterprises in National Equities Exchange and Quotations (NEEQ) from 2011 to 2012.The empirical results show that the financing efficiency of 54 enterprises in 2012 is lower than in 2011.The financing efficiencies of the hi-tech service,electronic information and bio-pharmaceutical industries in those 54 enterprises are in the higher interval,and those of the new energy,high efficiency energy saving and environmental protection industry are in low interval.
