大中型高技术企业创新效率测度与分解——基于DEA模型的实证分析

The Measure of China's Large and Medium-sized Hi-tech Enterprises Efficiency and Decomposition:An Empirical Analysis Based on DEA Model

把大中型高技术企业科技活动分解为科技成果产出和科技成果转化为生产力两阶段,运用KAO模型和在规模报酬可变的条件下构建的链形关联DEA模型,选取2000年、2005年和2007—2011年的大中型国有控股企业、大中型内资企业、大中型港澳台资企业和大中型外资企业的数据,具体分析计算各类企业的技术效率、纯技术效率和规模效率。实证研究表明:大中型国有控股企业、大中型内资企业的表现普遍弱于大中型港澳台资企业和大中型外资企业;科技成果转化为生产力的能力低和规模效率低是制约大中型国有控股企业和大中型内资企业发展的两大障碍。

In this paper,the activities of science and technology of large and medium sized high-tech enterprises are divided into scientific and technological achievements and scientific and technological achievements into productive forces in two stages.By using the KAO model and under the assumption of variable returns to scale a relational network DEA model,we first selected the date of large and medium-sized domestic enterprises,large and medium-sized state-owned enterprises,large and medium-sized Hong Kong,Macao and Taiwan funded enterprises and large and medium-sized and large foreign enterprise in2000,2005 2007-2011 year respectively;then we calculated and analyzed of all kinds of enterprises technical efficiency,pure technical efficiency and scale efficiency.Our empirical research shows that large and medium state-owned enterprises and large and medium-sized domestic enterprises performed generally less competitively than large and medium-sized Hong Kong,Macao and Taiwan-funded enterprises and large and medium-sized foreign-funded enterprises;we find low transformation of scientific and technological achievements into productivity and the scale of low efficiency are the two largest obstacles restricting the development of large and medium-sized state-owned enterprises and large and medium-sized domestic enterprises.
