摘要
文章基于2015—2022年我国沪深A股上市公司政府采购合同的微观数据,运用文本分析法识别政府采购合同信息,探究政府采购对企业新质生产力发展的影响与作用机制。结果显示:政府采购显著正向推动企业新质生产力提升,且这一结论经稳健性检验后依旧成立。政府采购对企业新质生产力发展的作用机制体现为两条路径:一是增强了企业商业信用融资能力;二是缓解了企业不确定性感知。异质性检验表明,政策效应在跨区域采购、高融资约束及高科技企业样本中更显著。因此,从需求侧政策工具视角拓展新质生产力培育理论框架,能够为政府采购政策的经济效应提供微观证据,为优化公共采购制度、完善新质生产力发展支持体系提供一定的政策启示。
Based on the microdata concerning government procurement contracts of China's Shanghai and Shenzhen A-share listed companies from 2015 to 2022,this study employs textual analysis to extract contract information and investigates the impacts of government procurement on enterprises'new-quality productive forces and their underlying mechanisms.The results demonstrate that government procurement significantly enhances enterprises'new-quality productive forces,which remains valid after robust tests.The mechanisms through which government procurement affects enterprises'new quality productive forces are manifested in both the enhancement of their trade credit financing capacity and reduced perception of uncertainty.Further,heterogeneity tests reveal stronger effects in cross-regional procurement,highly financing-constrained firms,and high-tech enterprises.Therefore,by expanding the theoretical framework for cultivating new-quality productive forces from the perspective of demand-side policy,this study provides micro-level evidence of the economic impacts of government procurement policies.It also offers policy insights for optimizing the public procurement system and supporting system for developing new-quality productive forces.
