数智赋能对制造业创新效率的影响机制研究

选取2015—2022年制造业上市公司的数据，分析数智赋能如何促进创新效率提升。实证结果表明，数智赋能可以显著提升制造企业的创新效率。如果制造企业的规模超过了门槛值，那么数智赋能对创新效率的作用是正向的，反之为负。随着政府支持力度变强，数智赋能对创新效率的促进作用逐渐变大。在数智赋能的过程中，制造企业进行开放式创新或者推动融资成本下降，都有利于提升创新效率，这两者发挥着中介作用。

The Study on Impact Mechanism of Digital Empowerment on Manufacturing Innovation Efficiency

Selecting the data of manufacturing listed companies from 2015 to 2022, how digital empowerment can improve innovation efficiency was analyzed. The empirical results indicate that digital empowerment can significantly improve manufacturing innovation efficiency. If the scale of manufacturing enterprises exceeds the threshold, then the effect of digital empowerment on innovation efficiency is positive; conversely, it is negative. With stronger government support, the promoting effect of digital empowerment on innovation efficiency is gradually increasing. In the process of digital empowerment, promoting open innovation or reducing financing costs for manufacturing enterprises is beneficial for improving innovation efficiency, and both play a mediating role.
