【摘要】 采用耦合协调度模型和障碍度模型对2011—2022年京津冀区域科技创新、协调发展与绿色生态三系统的耦合协调度的动态演化趋势及其障碍因素进行实证分析。结果表明：(1)研究期内京津冀区域三系统的评价指数均得到显著提升，并呈现出明显的地区差距，北京处于领先地位。(2)京津冀区域耦合协调水平总体发展态势良好，北京处于领先地位，天津紧随其后，河北的耦合协调水平最低。(3)发明专利申请授权量不足、工业污染治理投资占地区生产总值的比重较低以及技术市场成交额偏低均是阻碍京津冀区域耦合协调的主要原因。更多还原

【Abstract】 This paper makes an empirical analysis of the dynamic evolution trend and obstacle factors of the coupling coordination degree of science and technology innovation, coordinated development and green ecology in the Beijing-Tianjin-Hebei region from 2011 to 2022 with the model of coupling coordination degree model and obstacle degree model. The results showed that: Firstly, the evaluation indices of the three systems in the Beijing-Tianjin-Hebei region were significantly improved during the study period, and showed obvious regional disparities, with Beijing in the lead. Secondly, the overall development of the coupling and coordination level in the Beijing-Tianjin-Hebei region was good, with Beijing in the lead, followed by Tianjin, and Hebei lagging behind the most in terms of coupling and coordination development. Thirdly, insufficient authorization of patent applications for inventions, low investment in industrial pollution control as a proportion of regional GDP, and low turnover in the technology market were all major obstacles to the coupling and coordination of the Beijing-Tianjin-Hebei region.更多还原
