【摘要】 在将高技术产业投入产出分为技术研究开发和技术应用与改造两个阶段的基础上,利用链式DEA方法对我国17个高技术行业科技投入产出链效率进行研究,发现不同行业投入产出链效率差异较大,同一行业科技投入产出链的不同阶段效率也存在明显的不同;并按照效率特点将各个行业划分为"兼优"、"兼劣"等四类,通过深入分析不同类别行业效率的特点和原因,有针对性地提出了效率改进的政策建议。更多还原

【Abstract】 Based on the separation of S&T input-output process into technology development and technology application,the paper employs Series Network DEA to analyze the efficiency of S&T Input-Output Chain about Seventeen Sub-industries of China’s High-tech Industry.The study indicates the difference between sub-industries of S&T Input-Output Chain efficiency is high,and there is distinction between stages of the same sub-industry,then divides the sub-industries into four categories jading by the features of efficiency,and makes suggestions accordingly.更多还原
