数字经济发展的动力是大数据、人工智能等数字技术的进步，文章从数字技术的相关政策视角出发，基于国家级大数据综合试验区的准自然试验，利用2012-2019年省级面板数据，采用双重差分广义空间模型考察了数字技术的发展对企业创新能力的影响。研究发现：国家级大数据综合试验区能够发挥政策红利，显著提升企业创新能力，同时国家级大数据综合试验区提升了区域产学研合作水平，并且这种产学研合作在国家级大数据综合试验区赋能企业创新能力的过程中起到了部分中介作用。此外，国家级大数据综合试验区对本地和邻近地区均产生了显著的溢出效应，凸显了其示范引领作用正在逐步扩大。以上结论在更换被解释变量、变化处理组和政策冲击时间的反事实试验条件下依然成立，研究为评估国家级大数据综合试验区的政策效果提供了参考，在推动我国数字技术发展以及企业创新建设方面具有重要的理论和现实意义。

The development of the digital economy is driven by advances in digital technologies such as big data and artificial intelligence. This paper starts from the policy perspective of digital technology based on the quasi-natural experiments of national-level big data comprehensive pilot zones, examines the impact mechanism of the pilot policies of big data pilot zones on enterprise innovation capacity using provincial-level panel data from 2012-2019 by adopting a double-difference generalized spatial model. It is found that the establishment of big data pilot zones can bring into play policy dividends and significantly enhance the innovation capacity of local enterprises, while the establishment of big data pilot zones also strongly promotes the local industries-universities-research collaboration, and the industries-universities-research collaboration plays a part of intermediary role in the process of empowering the enterprise innovation capacity in big data pilot zones. In addition, the Big Data Pilot Zone has produced significant spillover effects on both local and neighboring regions, highlighting that the demonstration and leading role of the Big Data Pilot Zone is gradually expanding.And the above findings still hold under the counterfactual test conditions of replacing the explanatory variables, change treatment groups and policy shock times, and the study provides a reference for assessing the policy effects of the big data pilot zones, which has important theoretical and practical significance in promoting the development of China's digital technology and the construction of enterprise innovation.
