Change and Its Factors of Independent Innovation Efficiency of the State-owned Industrial Enterprises——DEA Analysis Based on the Provincial Panel Data of 1998-2007

In this paper,the authors research on the movement of independent innovation efficiency in the period of 1998-2007 in 30 provinces of China with the Malmquist index and we analyze the decomposition indicators of Malmquist index in conjunction with the three-yearreformofstate-ownedenterprises.We find that the effect of technological change andpuretechnical efficiency change are the key factors of how to improve the independent innovation capacity and total factor productivity of the State-owned Industrial Enterprises. Science and technology personnel redundant,low production capacity utilization,the ignoring of the development of new products and other issues are the main factors which hinder the state-owned industrial enterprises from improving the independent innovation efficiency. Introducing competition mechanism,improving the incentive mechanism,speeding up the construction of the system,increasing investment in research and development are effective measures to promote the reform of state-owned enterprises and improve independent innovation efficiency.
