摘要： 党的二十届三中全会对进一步全面深化改革推进高质量发展作出了新阐释新部署。依据党的二十届三中全会对推进经济高质量发展内涵的新概括，从新质生产力、数实融合、服务业高质量发展、现代化基础设施建设、产业链供应链韧性和安全5个维度构建了新的我国经济高质量发展水平评价指标体系。针对已有文献主要以国内为参照进行评价的不足，依据我国到2035年人均GDP达到中等发达国家水平的经济现代化发展目标，选取欧盟27国相应指标的平均数为国际参照，利用交叉熵无偏赋权法，对我国经济高质量发展水平进行评估。评估发现：2012—2021年，得益于我国在新质生产力、数实融合、现代化基础设施建设方面取得的长足进步，以及不断增强的产业链供应链韧性和安全水平，我国经济高质量发展水平得到显著提升，2021年达到了6792%，日益接近欧盟27国的平均水平。但要实现2035年发展规划目标，还需要针对已有的短板和弱项，进一步加快推进创新发展、绿色发展和人才强国建设。
