摘要
以中国64家独角兽上市企业为样本,采用三阶段DEA模型对独角兽企业的创新效率进行有效测算。结果表明,企业规模、成立年限、政府补贴、研发人员素质、外商直接投资和地区经济发展水平的提高有助于企业创新效率的提升,而产权性质、股权集中度则制约了企业创新效率的改进;清除环境影响和统计噪声后,多数企业的创新效率与纯技术效率上升,但仍处于较低水平。本文的实证结果有助于进一步提升独角兽企业的创新效率,也为独角兽企业后续的研究提供新的视角。
Taking 64 Unicorn listed companies in China as samples,this paper uses three-stage DEA model to effectively measure the innovation efficiency of Unicorn enterprises.The results show that the improvement of enterprise scale,establishment years,government subsidies,R&D personnel quality,foreign direct investment and the level of regional economic development contribute to the improvement of enterprise innovation efficiency,while the nature of property rights and ownership concentration restrict the improvement of enterprise innovation efficiency;after eliminating the environmental impact and statistical noise,the innovation efficiency and pure technical efficiency of most enterprises increase,but still remain at a low level.The empirical results of this paper help to further improve the innovation efficiency of Unicorn enterprises,and provide a new perspective for the follow-up research of Unicorn enterprises.
