摘要
基于政府采购合同信息与专利申请数据库,运用文本分析和专利共类分析方法,测算了2006—2021年285个地级及以上城市的政府数字采购规模与数实融合发展水平,考察了政府数字采购对数实融合的影响及作用机制。研究发现:通过促进数字基础设施建设的“筑巢”效应和加速数字市场主体培育的“引凤”效应,政府数字采购显著推动了数实融合发展;这一影响因采购类型和城市特征的差异而呈现出异质性,本地采购对数实融合的促进作用更强,而在政府数字关注度高、制度环境完善以及具有产业比较优势的城市中,政策效应更为显著;经济后果检验发现,政府数字采购对数实融合的推动作用能够助力新质生产力发展。研究结论不仅有助于弥补数实融合政策体系中需求侧研究的短板,也可为如何最大化发挥政府数字采购政策效应提供理论依据和实践参考。
Based on government procurement contract information and patent application databases,this study employs text analysis and patent co-classification analysis to measure the scale of government digital procurement and the development level of digital-real economy integration across 285 cities from 2006 to 2021,investigating the impact of government digital procurement on such integration and its underlying mechanisms.The results indicate that,through the“nest-building”effect of promoting digital infrastructure construction and the“phoenix-attracting”effect of accelerating the cultivation of digital market entities,government digital procurement has significantly advanced the development of digital-real economy integration.This impact exhibits heterogeneity depending on the type of procurement and city characteristics.Local procurement demonstrates a stronger promoting effect on digital-real economy integration,while the policy effect is more pronounced in cities with high government digital attention,well-developed institutional environments and comparative industrial advantages.Economic consequence tests reveal that the promoting effect of government digital procurement on digital-real integration can facilitate the development of new quality productive forces.The research conclusions not only help compensate for the shortcomings of demand-side research in the digital-real integration policy system,but also provide theoretical basis and practical reference for maximizing the policy effects of government digital procurement.
