在京津冀协同发展背景下，为找出京津冀科技投入产出差距及原因，构建京津冀科技投入产出评价指标体系，基于2016－2020年相关代表性数据，运用对比分析和主成分分析法研究京津冀地区和河北省各地市科技投入产出的均衡性。结果显示：京津冀三地科技投入产出存在明显差距，河北科技投入产出落后是主要原因；河北各地市科技投入产出强度存在较大梯度差，大致以石家庄为核心逐渐向冀南冀北减少，是制约京津冀科技协同发展的重要因素。根据研究结果，从发挥北京辐射作用和促进河北发展两方面提出建议，以促进雄安高质量发展、推动京津冀协同发展向更高水平迈进。

In the context of the coordinated development of Beijing-Tianjin-Hebei, in order to find out the gap and reasons of science and technology input-output in Beijing-Tianjin-Hebei, and build the evaluation index system of science and technology input-output in Beijing-Tianjin-Hebei, based on the relevant representative data from 2016 to 2020, the balance of science and technology input-output in Beijing-Tianjin-Hebei and cities in Hebei Province is studied by using comparative analysis and principal component analysis. The results show that there is a significant gap between the input and output of science and technology in Beijing-Tianjin-Hebei, and the backward input and output of science and technology in Hebei is the main reason; There is a large gradient difference in the input-output intensity of science and technology in various cities in Hebei, and it gradually decreases from Shijiazhuang to the South and north of Hebei, which is an important factor restricting the coordinated development of science and technology in Beijing-Tianjin-Hebei. According to the research results, suggestions are put forward from two aspects: giving play to the radiation role of Beijing and promoting the development of Hebei, so as to promote the high-quality development of xiong'an and promote the coordinated development of Beijing-Tianjin-Hebei to a higher level. higher level.
