中文摘要：

黄河三角洲高效生态经济区建设亟需区域科技创新能力的支撑，科学客观评价该区域科技创新能力具有重大现实意义。我们将黄河三角洲置于山东全省科技创新合作环境中，以黄河三角洲6市数据为依据，利用主成分分析和聚类分析方法对黄河三角洲6市科技创新能力进行分析与评价，得出以下结论：黄河三角洲科技创新发展迅猛，但发展水平依然较低；黄河三角洲科技创新发展潜力巨大，但区域发展不平衡加剧。因此，加大科技创新投入、优化科技创新支出结构、增强区域科技创新基础支撑是黄河三角洲科技创新合作发展的必然选择。

英文摘要：

Yellow River Delta Efficient Ecological Economic Zone dire need of the support of the regional scien- tific and technological innovation ability, scientific and objective evaluation of the regional scientific and technologi- cal innovation ability of great practical significance. The Yellow River Delta in Shandong Province, the province＇ s scientific and technological innovation cooperation environment, the Yellow River Delta city data, analysis and e- valuation of the Yellow River Delta city of scientific and technological innovation capability using principal compo- nent analysis and cluster analysis method, draw the following Conclusion： The rapid development of science and technology innovation in the Yellow River Delta, but the level of development is still low ; huge potential for the de- velopment of scientific and technological innovation of the Yellow River Delta, but intensified regional development imbalances. Therefore, increased technological innovation, optimize the expenditure structure of technological inno- vation, enhance the basic support of the regional scientific and technological innovation is the inevitable choice for the development of scientific and technological innovation of the Yellow River Delta cooperation.
