客观评估知识供应链效率状态，有利于促进区域高技术产业持续健康发展。借鉴知识供应链理论、DEA模型和聚类分析法，构建了一套较为系统的区域高技术产业知识供应链效率的分类评价体系；以中国高技术产业统计年鉴（2013-2014年）的相关数据为基础，从投入产出两个维度，给出了我国31省市区域高技术产业知识供应链效率的分类评估结果和优化对策。研究表明：我国高技术产业知识供应链效率总体较好，不同类型省市的知识供应链的投入产出规模差距悬殊；消除投入资源浪费，提升有效发明专利数和新产品销售收入，是相对落后省市改进高技术产业知识供应链效率的主要着力点。本研究成果为我国不同类别省市优化高技术产业知识供应链效率提供了实践启示。 

To evaluate objectively the efficiency condition of Knowledge Supply Chain (KSC) is conductive to promoting regional sustained and healthy development of hi-tech industries. Through using KSC theory, DEA model, cluster analysis method, this paper constructs a set of relatively systematic classified evaluation system of KSC efficiency in regard to regional hi-tech industries. Based on the statistical data of China’s hi-tech industries’ statistical yearbook (2013-2014), from the perspective of input and output, classified evaluation results and optimizing countermeasures for China’s 31 provinces and cities’ KSC efficiency in regard to regional hi-tech industries are provided in this paper. The study shows that the KSC efficiency of China’s hi-tech industry is generally quite good. However, great disparities exist for different scales of KSC input and output when comparing hi-tech industries in different types of provinces and cities. Eliminating the waste of input resource, enhancing the amount of efficient invention patents and the sales revenue of new products are main points to improve KSC efficiency of hi-tech industries in backward provinces and cities. The results of this study provide some practical enlightenments for different types of provinces and cities in improving KSC efficiency of hi-tech industries.
