摘要：企业创新知识主要来源于内部知识生产和外部知识吸收，不同的知识来源对企业创新绩效有不同的影响。本文以调查数据为基础，利用数据包络分析（DEA）对企业创新知识生产函数进行评测。结果表明，样本企业的创新知识生产效率整体上并不高，只有4604%的样本企业处于效率前沿面；同时，企业创新知识生产还存在弱规模报酬递减。样本企业在知识生产的所有投入要素上都存在一定的冗余，其中，外部知识特别是从产业集群、大学等研究机构获取的知识浪费严重；内部交流方面，也有超过一半的知识没有被充分利用；而在产出方面，专利产出严重不足。此外，本文还发现除了产业类型外，企业规模、产权类型、目标市场和品牌等对企业创新知识生产效率影响不显著。

Abstract: R&D and knowledge absorption, which are the majority sources for firms’ innovation, have a different effect on innovation performance. The efficiency of firms’ innovation is measured based on survey data using Data Envelopment Analysis (DEA). The results show that only 4604% of samples lie on the efficiency frontier and the return of scale are decreasing. Lots of inputs have been wasted, especially the knowledge obtained from the cluster and university; and more than half of knowledge has not been fully utilized because of poor internal communication; furthermore, the patent output is shortage. It is also found that expect industry types, all the factors including scale of firms, property right, target markets, as well as whether or not has a own brand, have insignificant effects on the efficiency.
