%X “宽带中国”战略不仅是国家网络基础设施建设的重要部署，也是企业实现数字化转型的良好契机。本文基于2010~2021年沪深A股上市企业的数据，采用多时点双重差分模型，实证检验了“宽带中国”试点对我国企业数字化转型的影响，并得出以下结论：“宽带中国”试点对企业数字化转型具有显著的正向促进作用，但政策效果对企业数字化转型存在异质性。就地区差异而言，“宽带中国”显著促进了中东部地区企业的数字化转型程度，而对西部地区企业影响并不显著，就行业差异而言，“宽带中国”对高新技术企业数字化转型具有显著的促进作用，而对非高新技术企业数字化转型的效用微乎其微。因此，我国应进一步扩大“宽带中国”试点范围，将西部地区和非高新技术企业作为战略重点，推动政策精准落实，全面充分激活企业数字化转型活力，助力经济高质量发展。<br />
The “Broadband China” strategy is not only an important deployment of national network infra-structure construction, but also a good opportunity for enterprises to achieve Digital transformation. Based on the panel data of A-share listed enterprises in Shanghai and Shenzhen from 2010 to 2021, this paper empirically tests the impact of the “Broadband China” pilot on the digital transformation of Chinese enterprises by using time-varying DID model, and concludes that the “Broadband China” pilot has a significant positive effect on the digital transformation of enterprises, but the policy effect is heterogeneous. In terms of regional differences, “Broadband China” significantly promotes the digital transformation of enterprises in the central and eastern regions, but has no significant impact on enterprises in the western region. In terms of industry differences, “Broadband China” has a significant role in promoting the digital transformation of high-tech enterprises, while the effect on the digital transformation of non-high-tech enterprises is minimal. Therefore, the government should further expand the scope of the “Broadband China” pilot, take the western region and non-high-tech enterprises as strategic priorities, promote the precise implementation of policies, fully activate the vitality of digital transformation of enterprises, and promote high-quality economic development.
