【摘要】 作为制造与服务融合发展的新业态模式，服务型制造成为制造业高质量发展和现代化产业体系建设的重要内容。基于2012—2021年制造业上市公司数据，系统考察了数字基础设施对服务型制造的影响及作用机制。研究发现，数字基础设施建设显著推动了服务型制造，并且在小型企业、高竞争行业和高生产性服务业集聚地区效果更明显。机制检验表明，数字基础设施对服务型制造的促进作用主要是通过创新效应和成本效应实现的。具体来说，数字基础设施提高了制造业的专利申请数量和专利申请质量，降低了市场交易成本。上述研究结果为数字经济背景下推动制造业和服务业深度融合发展提供了可参考的经验证据。更多还原

【Abstract】 As a new industry mode of manufacturing and service integration and development,service-oriented manufacturing has become an important content of the high-quality development of manufacturing industry and the construction of modernized industrial system.Based on the data of listed companies in the manufacturing industry from 2012 to 2021,the impact and mechanism of digital infrastructure on service-oriented manufacturing are systematically examined.The study found that digital infrastructure significantly boosted service-based manufacturing,and that the effect was more pronounced in areas with small firms,highly competitive industries and high levels of productive services concentration. Mechanism tests show that digital infrastructure facilitates servicebased manufacturing mainly through innovation effects and cost effects.Specifically,digital infrastructure increases the number of patent applications and the quality of patent applications in the manufacturing sector and reduces market transaction costs.The research provides empirical evidence for promoting the development of deep integration of manufacturing and service industries in the context of digital economy.更多还原
