Abstract

Digital technology innovation has become essential to China's sustainable, low-carbon social development strategy. However, its spatial impact on carbon reduction and efficiency is unclear. This study innovatively utilizes patent search to define digital technology innovation and spatial econometric modeling to assess its association with total-factor carbon emission efficiency (TCEE) in 286 Chinese cities. There are some exciting research findings: (1) Digital technology innovation effectively accelerates local TCEE and contributes to TCEE in surrounding cities through spatial spillover effects. (2) The heterogeneous results show that digital technology innovation increases the local TCEE in the western region, inhibits the local TCEE in the eastern and northeastern areas, and shows apparent positive spillover effects in both the eastern and western areas; the positive effects of digital technology innovation on TCEE in non-resource cities and small cities are all-encompassing. (3) Both industrial structure upgrading and optimization can enhance the spatial spillover effect of digital technology innovation on TCEE; both formal and informal environmental regulations (ER) can effectively accelerate the TCEE enhancement effect of digital technology innovation on local and surrounding cities. (4) Digital technology innovation affects the TCEE of trading partners through domestic bilateral trade. This manuscript provides an actionable reference for measuring digital technology innovation and China's path to achieving an efficient low-carbon pathway.

数字时代的全要素碳排放效率导航：来自产业结构、环境法规和贸易溢出的案例研究

数字技术创新已成为中国可持续低碳社会发展战略的关键。然而，其对碳减排和碳效率的空间影响尚不明确。本研究创新性地利用专利检索对数字技术创新进行了定义，并利用空间计量经济模型对中国 286 个城市的数字技术创新与全要素碳排放效率（TCEE）的关系进行了评估。研究结果令人振奋：（1）通过空间溢出效应，数字技术创新有效加速了当地的碳排放效率，并促进了周边城市的碳排放效率。(2）异质性结果显示，数字技术创新提高了西部地区的本地 TCEE，抑制了东部和东北地区的本地 TCEE，在东部和西部地区都表现出明显的正溢出效应；数字技术创新对非资源型城市和小城市 TCEE 的正效应是全方位的。(3）产业结构升级与优化均能增强数字技术创新对TCEE的空间溢出效应；正式与非正式环境规制（ER）均能有效加速数字技术创新对本地及周边城市TCEE的提升效应。(4) 数字技术创新通过国内双边贸易影响贸易伙伴的 TCEE。本手稿为衡量数字技术创新和中国实现高效低碳的路径提供了可操作的参考。
