中文摘要：

本文利用共同前沿理论和DEA模型测算分析2005~2010年我国不同性质企业技术创新效率差异、损失来源以及影响机制。结果表明：考察期内我国企业创新效率整体水平偏低，还有42．19／6的提升空间，纯技术效率和规模效率均不高。共同前沿下效率值均不超过群组前沿下效率值，TGR值显示，外资、港澳台资与内资企业的技术差距均位于0．2～0．4，且存在差距继续扩大的风险。不同性质企业效率损失根源存在显著差异，港澳台资和外资企业效率缺失主要受制于落后的企业管理水平；内资企业则因生产技术差距和管理不当所造成的效率损失均占有一定比例。企业性质、企业规模、市场竞争程度和政府金融支持对效率提升具有积极影响，企业规模在政府金融支持与效率关系中起负向调节作用。

英文摘要：

By using the theory of meta-frontier and DEA model, this paper measures different properties enterprises＇ technology innovation efficiency in China from 2005 to 2010, we decompose the non-efficiency value, and then analyze the affecting factor. The results show that. innovation of enterprises overall efficiency is low during the examined period, there is 42.1% to promote. Pure technical efficiency and scale efficiency are both not high. Under the meta-frontier, the efficiency is less than the frontier efficiency value. TGR value shows that. the technology gap between foreign enterprises and domestic enterprises are located in 0.2---0.4, and there is a risk of further widening the gap.
