我国ICT企业技术创新效率的实证研究——基于DEA方法视角

An Empirical Study on the Technology Innovation Efficiency of Chinese ICT Corporations: Based on DEA Model

利用数据包络分析法(DEA),针对选取的31家沪深两市上市ICT企业,测量了其在2011年至2014年间企业的技术创新效率。研究结果表明:总体上,ICT企业在2011年至2014年间的平均技术效率值分别为0.646、0.584、0.688和0.622,总平均技术效率值为0.635,这意味着相关企业在技术创新过程中的资源浪费程度接近40%。就企业个体而言,31家样本企业中只有4家(法拉电子、国电南瑞、华微电子和长城信息)表现最佳,连续四年技术效率值都为1,而其他无效率的ICT企业则在创新资源投入规模和资源的使用效率方面存在诸多问题,亟待改进管理现状。

31 ICT enterprises listed on Shanghai Stock Exchange and Shenzhen Stock Exchange are surveyed, using data envelope analysis technique （DEA）, for their technological innovation efficiency for 2011 -2014 period. The finding shows ： on the whole, the mean technological innovation efficiencies of the studied ICT enterprises are 0. 646, 0. 584, 0. 688, and O. 622 respectively, for 2011 - 2014, with an overall mean value at 0. 635, signifying that these enterprises operated at a resource wastage rate close to 40% in the process of technological innovation. In view of individual enterprises, only 4 out of the 31 sample enterprises （Faratronic, Nari Technology, Jilin Sino-Microelectronics, and Greatwall Information Industry） registered optimum performance by achieving an efficiency of 1 for four years on end. The rest inefficient ICT enterprises experienced quite a few problems with innovation resource input magnitude and resource utilization efficiency, warranting an immediate improvement in their current management.
