【摘要】 基于2011—2022年的省级面板数据，实证检验数字经济对制造业高质量发展的影响效应与影响机理。研究结论显示：数字经济有助于促进制造业高质量发展，采用替换变量、加入滞后变量以及工具变量法后，上述结论仍然成立。进一步研究发现，数字经济的影响具有结构性效应，数字产业化对制造业高质量发展的促进作用相比于产业数字化更强；门槛回归模型与空间杜宾模型的结果表明，数字经济对于制造业高质量发展的影响具有明显的非线性特征和空间溢出特征；数字经济对制造业高质量发展的影响效应存在显著的区域异质性，地区经济越发达，数字经济对制造业高质量发展的激励效应越显著。中介效应模型结果表明，数字经济通过提高人力资本，激励产业升级，促进技术创新，降低交易成本，进而促进制造业高质量发展。更多还原

【Abstract】 The article is based on provincial panel data from 2011 to 2022 to empirically tests the influence effect and mechanism of digital economy on the high-quality development of the manufacturing industry. The research conclusion shows that the digital economy helps promote high-quality development of manufacturing industry. After using replacement variables, incorporating lagged variables, and instrumental variable methods, the above conclusion still holds. The results of threshold regression model and spatial Durbin model indicate that the impact of digital economy on the high-quality development of manufacturing industry has obvious nonlinear characteristics and spatial spillover characteristics. There is significant regional heterogeneity in the impact of the digital economy on the high-quality development of the manufacturing industry. The more developed the regional economy is, the more significant the incentive effect of the digital economy on the high-quality development of the manufacturing industry. The results of the mediation effect model indicate that the digital economy promotes high-quality development of the manufacturing industry by increasing human capital, stimulating industrial upgrading, promoting technological innovation, and reducing transaction costs.更多还原
