摘　　要：数字经济重组要素资源,重塑经济发展结构,促进产业融合和创新效率,驱动城市经济高质量发展。本文构建了数字经济发展水平指标与城市经济效率指数,实证研究了数字经济对城市经济效率的空间影响,并基于因果渠道检验对数字经济通过技术创新与产业结构升级影响城市经济效率的机制进行了检验。研究结果表明:首先,数字经济能够直接驱动城市经济效率提升;其次,数字经济本身具备提升城市经济效率的空间效应;最后,数字经济可以通过产业结构优化与技术进步改善城市经济效率,但技术效率改善的机制作用却不显著。因此,应立足城市实际情况,制定更具空间指向的城市发展政策,把握数字经济发展契机,充分发挥数字经济的辐射带动作用,推进产业数字化与数字产业化融合,破除行政壁垒,构建长三角高质量协同发展网络,精准助力城市经济效率提升。Digital economy re-organizes factor resources,reshapes economic development structure,promotes industrial integration and innovation efficiency to promote high-quality urban economic development.This paper constructs indicators of digital economy development level and urban economic efficiency index,empirically studies the spatial impact of digital economy on urban economic efficiency,and tests the mechanism of digital economy impact on urban economic efficiency through technological innovation and industrial structure upgrading based on the cause and effect model.The results show that:firstly,digital economy can directly promote the improvement of urban economic efficiency.Secondly,digital economy itself has the spatial effect of improving urban economic efficiency.Finally,digital economy can improve urban economic efficiency through industrial structure optimization and technological progress,but the mechanism of technological efficiency improvement is not significant.Therefore,it should be based on the actual situation of the city,formulate more spatially oriented urban development policies,seize the development opportunities of the digital economy,fully utilize the radiating and driving role of the digital economy,promote the integration of industrial digitalization and digital industrialization,break down administrative barriers,build a high-quality cooperative development network of the Yangtze River Delta,and accurately support the improvement of urban economic efficiency.
