信息基础设施建设与数智化创新:“赋能” 还是“负能” ——来自“宽带中国”战略的经验证据

Information infrastructure construction and digital-intellectual innovation: empowerment or negative energy: Empirical evidence from the “Broadband China” strategy

摘要:

立足于信息基础设施建设带来的时代红利,探讨其对物联网、云计算、人工智能等数智化创新产生的影响及其驱动路径具有重要意义。 本文使用 2011—2021 年中国 284 个城市面板数据,实证检验信息基础设施建设对数智化创新的影响。 研究发现:以“ 宽带中国” 战略表征的信息基础设施建设能够有效提升数字技术、5G 技术、人工智能技术、信息技术和电子商务技术等数智化创新水平。 该结论经过多种稳健性检验后依然成立。 机制检验表明,信息基础设施建设通过提高数智化人才集聚度和优化数智化产业环境,从而增强数智化创新能力。 异质性结果显示,信息基础设施建设对数智化创新产生的积极影响因区域和交通特征差异表现出明显的地理梯度效应,整体上从中西部地区到东部地区、从非高铁开通城市到高铁开通城市逐步增强。 本文研究为优化信息基础设施建设空间布局和差异化提升数智化创新水平提供理论依据。

Abstract:

Based on the era of dividends brought about by the construction of information infrastructure, it is of great significance to explore the impact of it on digital-intellectual innovations such as digitalization, cloud computing, and artificial intelligence. The driving path were discussed. Utilizing data from 284 Chinese cities from 2011 to 2021, an empirical model of information infrastructure construction on digital- intellectual innovation was constructed. It finds that the construction of information infrastructure, represented by the “ Broadband China ” strategy, effectively enhances the level of technological innovation in digital-intellectual innovation, such as digital technology, 5G technology, artificial intelligence technology, information technology and e-commerce technology. The conclusion remains valid after various robustness tests. Mechanism tests show that information infrastructure construction enhances digital-intellectual innovation by increasing the concentration of digital-intellectual talent and optimizing the digital-intellectual industrial environment. Heterogeneity results show that the positive impact of information infrastructure construction on digital-intellectual innovation exhibits a clear gradient effect across different regions, progressively strengthening from the central-western to the eastern regions, and from cities without high-speed rail to those with high-speed rail. It provides a theoretical base for optimizing the spatial layout of information infrastructure construction and enhancing the capacity of digital-intellectual innovation.
