  我国经济已由高速增长阶段转向高质量发展阶段，工业作为实体经济的核心，推动工业高质量发展是实现经济高质量发展的重要抓手和关键环节。当前，工业发展存在关键领域的技术创新能力不足，产能过剩问题，增长方式相对粗放，质量和效率亟待提高等问题。面对“第四次工业革命”，如何推动数字技术与实体经济深度融合，促进传统产业转型升级，释放数字经济动能，实现工业高质量发展，成为当前亟需解决的问题。
  本文对数字经济和工业高质量发展相关文献进行梳理和归纳，厘清数字经济发展的相关理论，深入分析数字经济对工业高质量发展的积极影响以及数字经济赋能工业高质量的潜在阻碍。考虑到现有研究在研究区域和研究变量上的局限性，本文基于2010-2020年的省级面板数据进行实证研究。首先基于新发展理念和工业高质量发展内涵，从创新驱动、结构优化、绿色高效、国际竞争力、社会效益五个维度构建综合评价指标体系，对地区工业高质量发展水平进行测度并分析其时空变化特征；其次，划分数字经济行业，对数字经济规模进行测算；最后通过构建面板平滑转移模型、空间杜宾模型等，研究数字经济影响工业高质量发展的区域异质性，非线性特征和空间溢出效应。研究得到如下结论：
  第一，工业高质量发展整体水平呈稳步上升态势，但是区域工业高质量发展不平衡，呈阶梯式空间发展格局，同时工业高质量发展具有都市联动效应。
  第二，数字经济规模两极分化严重，存在明显的“数字鸿沟”现象。从数字经济发展趋势来看，数字鸿沟现象略有改善，整体的数字经济规模在持续扩大。
  第三，数字经济对工业高质量发展有推动作用，且这种推动作用具有区域异质性和非线性动态特征。区域异质性方面，数字经济对工业高质量发展的促进作用在中部地区最大，东部地区次之，西部地区不显著。非线性特征方面，数字经济对工业高质量发展的促进作用具有边际效应递增的特点，且数字经济的规模突破一定阈值后，其对工业高质量发展的促进作用会被放大。
  第四，数字经济对本地区的工业高质量发展具有显著促进作用，但对其他地区的工业高质量发展存在负的空间溢出效应。

  China's economy has changed from a stage of rapid growth to a stage of high-quality development. At present, there are problems in industrial development, such as insufficient innovation capacity, overcapacity, relatively extensive growth mode, and urgent need to improve quality and efficiency. In the face of the "industry 4.0", how to release the kinetic energy of the digital economy, and achieve high-quality industrial development has become an urgent problem to be solved.
  This paper combs and summarizes the literature related to digital economy and high-quality industrial development, clarifies the relevant theories of digital economy development, and deeply analyzes the positive impact of digital economy on high-quality industrial development and the potential obstacles of digital economy enabling high-quality industry. Considering the limitations of existing research on research regions and research variables, this paper conducts empirical research based on provincial panel data from 2010 to 2020. First, based on the new development concept, a comprehensive evaluation index system is constructed from five dimensions: innovation, structural optimization, green efficiency, international competitiveness, and social benefits to measure the level of high-quality industrial development in the region and analyze its spatio-temporal dynamic characteristics. Secondly, divide the digital economy industry and calculate the scale of the digital economy. Finally, the PSTR model and spatial Dubin model are constructed to study the regional heterogeneity, nonlinear characteristics and spatial spillover effects of digital economy on high-quality industrial development. The following conclusions are drawn:
  First, the overall level of high-quality industrial development is steadily rising, but the high-quality development of regional industries is uneven, showing a ladder like spatial development pattern. At the same time, high-quality industrial development has an urban linkage effect.
  Second, the scale of the digital economy is seriously polarized, and there is an obvious "digital divide". From the perspective of the development trend of the digital economy, the digital divide has narrowed slightly, and the overall scale of the digital economy has continued to expand.
  Third, the digital economy can promote the high-quality development of industry, which is characterized by regional heterogeneity and nonlinear dynamics. In terms of regional heterogeneity, the digital economy plays the largest role in promoting high-quality industrial development in the central region, followed by the eastern region, and the western region is not significant. In terms of non-linear characteristics, the promotion of digital economy on high-quality industrial development is characterized by increasing marginal effect. After the scale of digital economy breaks through a certain threshold, its promotion on high-quality industrial development will be amplified.
  Fourth, the digital economy has a significant role in promoting the high-quality industrial development of this region, but it has a negative spatial spillover effect on the high-quality industrial development of other regions.
