Digital technology innovation is the core driving force for the high-quality development of the digital economy, and in-depth exploration of the regional distribution pattern and formation mechanism of digital technology innovation in China is conducive to the rational layout and coordinated development of the inter-provincial digital economy. Based on the Reference Relationship Table of the Classification of Core Industries of Digital Economy and the International Patent Classification (2023), the patent authorization data of digital technology from 2012 to 2022 were obtained, and the spatiotemporal situation of China's digital technology innovation was analyzed by using ArcGIS software, Dagum's Gini coefficient, and Moran's I index, and the spatial Dubin panel model was used to explore the influencing factors of digital technology innovation. It is found that: (1) the scale and vitality of China's digital technology innovation have increased significantly, and there are obvious spatial differentiation characteristics, and the innovation level of "eastern coastal-central and western interior" is decreasing, forming a cluster distribution pattern in the Yangtze River Delta region, Beijing, Guangdong, and other places, and the degree of agglomeration is decreasing. (2) The overall regional differences in China's digital technology innovation are large, the differences between the East and the West dominate the interregional differences, and the net differences between regions are the main factors leading to regional differences. (3) There is a significant positive spatial correlation between the scale and vitality of digital technology innovation, which has a significant spatial spillover effect. (4) The results confirm that the level of economic development, digital access, financial scientific and technological support, technology market development level, and R&D intensity have a significant positive impact on the scale and vitality of digital technology innovation; The investment in scientific and technological talents has a significant positive impact on the scale of digital technology innovation, but has no significant impact on the vitality of digital technology innovation.
数字技术创新是数字经济高质量发展的核心驱动力，深入探究中国数字技术创新的区域分布格局和形成机制，有利于促进省际数字经济的合理布局和协调发展。本文基于《数字经济核心产业分类与国际专利分类对照关系表（2023）》，获取了 2012—2022 年数字技术专利授权数据，运用 ArcGIS 软件、Dagum 的基尼系数和 Moran's I 指数分析了中国数字技术创新的时空格局，并采用空间 Dubin 面板模型探究了数字技术创新的影响因素。结果表明：①中国数字技术创新规模和活力显著提升，且存在明显的空间分异特征，“东部沿海—中部—西部内陆”的创新水平逐渐降低，呈现出以长三角地区、京津冀、粤港澳等为核心的集聚分布格局，集聚程度逐渐减弱。②中国数字技术创新的区域差异整体较大，东西差异主导着区域间差异，净区域差异是导致区域差异的主要因素。③中国数字技术创新规模和活力之间存在显著的正向空间相关性，具有显著的空间溢出效应。④研究结果证实，经济发展水平、数字接入水平、金融科技支撑水平、技术市场发展水平和研发强度对数字技术创新的规模和活力均具有显著正向影响；科技人才投入对数字技术创新的规模具有显著正向影响，对数字技术创新的活力没有显著影响。
