数字技术是数字经济核心驱动力，与实体经济深度融合加速优化重构生产要素体系，催生出数字化生产要素。本文从数字技术是生产要素赋能型技术视角，拓展数字技术为资本赋能型技术和劳动赋能型技术，引入CES生产函数中推演TFP增长公式，清晰展现了数字技术赋能路径，并基于1990-2018年中国制造业27个细分行业面板数据进行参数估计。研究发现：数字技术是TFP增长主要驱动力，中国制造业TFP年增长率4.9%，其中数字技术贡献4.1%；数字技术和要素配置均偏向于资本，数字化背景下资本与劳动替代弹性为0.763（互补关系）；数字技术偏向和要素配置偏向均已由抑制演变为促进，两者交互项已由促进演变为抑制并呈倒U特征。

Digital technology is the core driving force of the digital economy. Its deep integration with the real economy accelerates the optimization and reconstruction of the production factor system, and gives birth to digital production factors. Taking digital technology as a technology empowering production factors, we expand digital technology to capital-enabling technology and labor-enabling technology. Then we introduce the CES production function to derive the TFP growth formula, which clearly shows the path of digital technology empowerment. Based on the panel data of 27 sub-sectors of China's manufacturing sector from 1990 to 2018, parameter estimation is conducted. It is found that digital technology is the main driving force for the growth of TFP. The annual growth rate of TFP in China’s manufacturing industry is 4.9% while digital technology contributes 4.1%. Digital technology and factor allocation are biased towards capital. The elasticity of substitution of capital to labor under the digital background is 0.763 (complementary relationship). Both the digital technology bias and the element allocation bias have evolved from suppression to promotion. The interactive items between them have evolved from promotion to suppression, showing the characteristics of an inverted U.
