摘要
在国内外多重超预期因素的影响下,新型信息基础设施作为数字经济发展的底层支撑,对增强经济韧性具有重要意义。本文基于地级市4G基站数据构建新型信息基础设施指标,从技术属性、渗透属性与连接属性出发,系统研究了新型信息基础设施对经济韧性的影响及作用机制。本文研究发现,新型信息基础设施建设对经济韧性的影响具有显著促进作用,且该结论通过一系列稳健性检验后依然成立。进一步研究表明,新型信息基础设施建设增强经济韧性的主要渠道为提高创新积累、实现风险分担,而生产匹配渠道的激励作用在全样本中尚未显现。同时,新型信息基础设施建设的促进效应在创新积累、风险分担与生产匹配层面突破了距离衰减法则的制约,是偏远地区实现经济韧性的一种新思路。异质性分析表明,在人口密度较大、生产效率较高以及产业结构较优化的地区,新型信息基础设施的建设对经济韧性的提升作用更为明显。本研究为推动我国数字经济健康发展、探索增强经济韧性路径提供了理论依据与经验支撑。
The new information infrastructure,which serves as the foundation for the growth of the digital economy under the influence of numerous unanticipated domestic and international forces,is crucial to the improvement of economic resilience.Based on the data on 4Gmobile base stations in prefecture-level cities,this article develops indicators measuring new information infrastructure and systematically examines the influence of new information infrastructure on economic resilience and the mechanism of its function from the perspective of technical attributes,penetration attributes,and connection attributes.After a number of robustness checks,it is concluded that new information infrastructure construction has a positive impact on economic resilience.Further investigation reveals that while the incentive effect of the production matching channel has not yet been demonstrated in the entire sample,it is primarily through boosting innovation accumulation and risk sharing that the new information infrastructure construction improves economic resilience.To achieve economic resilience in remote places,the law of distance decay is broken at the level of innovation accumulation,risk sharing,and production matching by the facilitating influence of the development of new information infrastructure.According to the heterogeneity study,regions with larger population densities,higher production efficiency,and ideal industrial structures are more significantly affected by the development of new information infrastructure in terms of economic resilience.This paper offers a theoretical framework and empirical support for encouraging the robust growth of China's digital economy and examining ways to improve economic resilience.
