中文摘要：

京津冀地区是中国重要的经济区域,但近年来三地发展水平出现分化,京津两市与河北省的差距拉大,有出现“极化”效应的可能。通过构建创新效率的评价体系,对京津冀三地3年的技术创新投入和产出作DEA方法分析,结果表明河北省的创新效率明显低于京津两市。京津冀三地在综合发展水平、劳动力素质、R＆D活动经费投入和外商投资企业的技术溢出水平上的差异,是这种技术创新效率产生差异的原因。

英文摘要：

Beijing, Tianjin and Hebei is an important economic area in China, but the development of the threeplaces is different, which would lead to “polarization” . This paper constructs an efficiency evaluation system to analyzethe innovation performance in the recent three years. The output of DEA model suggests that the innovation efficiencyof Hebei province was significantly lower than that of the two cities. The reasons for the differences of innovationefficiency are discussed.
