文档名：数字经济、产业升级与经济高质量发展
摘要：快速发展的数字经济已日益成为推动经济高质量发展的重要力量和关键驱动因素.在构建经济高质量发展与数字经济发展评价指标体系并使用熵值法进行测算的基础上,利用长江经济带11省市2013—2019年的面板数据,实证探究数字经济推动经济高质量发展的内在机制.结果表明:数字经济对长江经济带高质量发展有显著的正向促进作用;从区域异质性来看,长江经济带下游地区的数字经济发展对经济高质量发展的推动作用要强于上游、中游地区;产业升级在数字经济推动经济高质量发展的过程中发挥显著的中介效应且其占比为34.77％,这充分说明促进产业升级是数字经济推动经济高质量发展的重要路径;产业升级的中介效应存在明显的地区差异:下游地区最强,上游地区次之,中游地区产业升级中介效应不明显.门槛模型检验结果显示:数字经济对长江经济带高质量发展存在双门槛效应,当跨越门槛值后影响效应呈递增趋势,数字经济对经济高质量发展的作用呈现非线性边际效应递增特征.
