摘　　要：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。研究发现:绝大多数创业板上市公司可比创新效率较低,存在较大改进空间,其中平均可比综合创新技术效率最高的是广播、电视、电影和影视录音制造业,最低的是计算机、通信和其他电子设备制造业;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、技术提升创新效率比单纯改变规模更有效。Taking 354 listed companies on GEM as the sample,this paper reveals the innovation efficiency distribution of the listed companies on GEM,and evaluats the technical efficiency of enterprise innovation from the perspective of heterogeneous industry by polarization modeling and DEA secondary superposition. Results show that most of the comparable innovation efficiency is low,and there is a big space to improve for the listed companies on GEM; in terms of the average comparable comprehensive innovation technology efficiency,the highest are the broadcast industry,TV industry,film industry,and video recording industry; the lowest are computer,communications and other electronic equipment manufacturing industry;there are larger imbalance in structure of enterprise innovation investment,and the effectiveness of the RD input have not been released efficiently; it＇s more effective to promote innovation efficiency by improvement of management,motivation,and technology than altering the scale simply.
