摘要：数字技术创新既是促进区域协调发展取得新突破的关键力量，也是实现共同富裕、迈向中国式现代化的重要一环。为进一步深化该主题研究，将数字技术创新的区位因素引入新经济地理学的自由资本模型，在理论上阐述了数字技术创新推动区域协调发展的内在机理，并从国际专利分类（IPC）层面识别出2009—2022年全国239个城市53万余件数字技术申请专利，通过构建改进收敛性分析模型对数字技术创新影响区域协调发展的机制路径开展实证检验。研究结果显示，数字技术创新对区域发展指数及其分项指标具有收敛效应，该结论经过一系列稳健性检验后依然成立。此外，数字技术创新对区域发展指数的赋能效应在中部地区与非中心城市较强，在东部地区、西部地区以及中心城市较弱，在一定程度上缩小了区域发展差距。交互效应检验结果表明，财政科学支持、公共数据共享、制度型开放等政府协同治理手段对数字技术创新的区域收敛效应起正向交互作用。机制效应检验结果表明，数字技术创新可以通过优化资源配置、破除产业同构、促进技术转移等区域协作互动方式来缩小区域差异。研究结论为推进数字技术创新发展、释放其区域收敛效应、建设高质量发展的区域经济布局提供了政策启示。

Abstract: With the continuous advancement of a new round of technological revolution and industrial transformation, digital technology innovation has become an important driver for the transformation of regional economic growth, playing a key role in promoting breakthroughs in coordinated regional development. This paper first introduces the location factors of digital technology innovation into the free capital model of new economic geography, and deduces the potential impact of digital technology innovation on coordinated regional development. This paper finds that digital technology innovation can narrow the regional development gap after reaching a certain level of development. Then, based on the IPC number, more than 530,000 digital technology patent applications are identified in 239 cities in China from 2009 to 2022. A comprehensive evaluation system for the regional development index is constructed from five aspects: economic development, people's livelihood, public services, infrastructure, and ecological environment. An improved convergence analysis model is built to empirically test the mechanism of digital technology innovation affecting coordinated regional development. This paper finds that digital technology innovation has a convergence effect on the regional development index, and this conclusion still holds after endogeneity treatment and robustness tests. The sub-indicator test results show that digital technology innovation can significantly accelerate the convergence speed of the abovementioned five indicators. The heterogeneity analysis indicates that the empowering effect of digital technology innovation on the regional development index is stronger in the central region and non-central cities, while weaker in the eastern region, western region, and central cities. This has to some extent narrowed the overall regional development gap of the economy and provided the possibility for non-central cities to catch up with central cities. The results of the interaction effect test indicate that the government's collaborative governance measures such as fiscal science support, public data sharing, and institutional openness have a positive moderating effect on the regional convergence effect of digital technology innovation. The mechanism analysis indicates that digital technology innovation can narrow regional differences by optimizing resource allocation, breaking industrial homogeneity, and promoting technology transfer.

Based on the above conclusions, this paper proposes the following targeted countermeasures and suggestions. Firstly, we should fully leverage the inclusive development effect of digital technology innovation and improve the unbalanced regional development pattern. Secondly, we should focus on improving the government's overall development and policy system, providing conditions for unleashing the regional convergence effect of digital technology innovation. Finally, it is necessary to strengthen regional cooperation and interaction mechanisms through digital technology innovation, providing strong guarantees for high-level coordinated regional development.

Keywords: digital technology innovation; coordinated regional development; improved convergence analysis; government collaborative governance; regional collaboration and interaction
