企业创新效率的可比测度

The comparable measure of the enterprise innovation efficiency

摘要:

本文以354家创业板上市公司为样本,通过极化模拟和DEA二次叠加,揭示创业板上市公司的创新效率分布, 实现了异质行业下企业创新技术效率的可比评价。本文通过研究发现：通过极化模拟和二次叠加改进的DEA方法,对于异质行业下企业可比创新效率的测度是有效的。其次,3/4的创业板上市公司可比创新效率低于0.4,存在较大改进空间；平均可比综合创新技术效率最高的是广播、电视、电影和影视录音制作业,再次是软件和信息技术服务业,最低的是计算机、通信和其他电子设备制造业；最后,企业创新投入结构上存在较大的不平衡性,研发经费投入的有效性没有得到应有的释放；通过改善管理、激励、技术来提升创新效率比单纯改变规模更有效。

Abstract:

Taking 354 listed companies on GEM as the sample, this paper evaluates the technical efficiency of enterprise innovation from the perspective of heterogeneous industry by Polarization modeling and DEA secondary superposition, and reveals the innovation efficiency distribution of the listed companies on GEM. the conclusions are as follows: (1) That the improving DEA method by Polarization modeling and DEA secondary superposition is used to measure the enterprise comparable innovation efficiency of heterogeneous industry is effective; (2) Three quarters of the comparable innovation efficiency of the listed companies on GEM are less than 0.4, and there is a big space for improvement; (3) In terms of the average comparable comprehensive innovation technology efficiency, the most are the broadcast industry, TV industry, film industry, and video and radio production; the next are software and information service industry; the lowest are computer, communications and other electronic equipment manufacturing industry; (4) The results also shows there are larger imbalance in structure of enterprise innovation investment, and the effectiveness of the R D input have not been released efficiently. And, it’s more effective to promote innovation efficiency by improvement of management, motivation, and technology than altering the scale simply.
