【摘要】 基于2015—2023年长三角地区新能源汽车企业经验数据，构建多元回归模型和中介效应模型，明确数字营商环境对新能源汽车企业创新效率的影响路径，揭示其过程中的中介效应和调节效应。研究发现：数字营商环境显著促进新能源汽车企业创新效率，且在进行多种稳健性检验后结果依然可靠；数字化转型在数字营商环境与企业创新效率之间起到重要的中介作用；异质性分析结果显示，新能源汽车企业所有权和规模在数字营商环境对企业创新效率的影响上存在调节效应。更多还原

【Abstract】 Based on the empirical data of new energy vehicle enterprises in the Yangtze River Delta region from 2015 to 2023,multiple regression models and mediating effect models were constructed to clarify the impact path of the digital business environment on the innovation efficiency of new energy vehicle enterprises and reveal the mediating and moderating effects in the process.The research findings are as follows: The digital business environment significantly promotes the innovation efficiency of new energy vehicle enterprises, and the results remain reliable after multiple robustness tests.Digital transformation plays an important mediating role between the digital business environment and enterprise innovation efficiency.The results of the heterogeneity analysis show that the ownership and scale of new energy vehicle enterprises have moderating effects on the impact of the digital business environment on enterprise innovation efficiency.更多还原
