内容简介：

Digital services have become an integral part of our work and daily lives. This paper examines how the digital infrastructure promotes total factor productivity (TFP) and labor productivity in China. Using a diverse range of datasets with varying levels of detail and granularity during 2003-2019, we find that on average digital infrastructure investment contributes to China's TFP growth by 0.25 to 0.52 percentage points every year. In addition, our findings underscore significant wage increases in industries that heavily rely on digital infrastructure, demonstrating the capacity of digital technology to favor skilled labor and female workers. When comparing with the US, we find that China still lags behind in terms of digital infrastructure investment volumes, annual growth rate and average reliance of digital infrastructure, while its contribution to TFP growth in China is 1.7 to 2.5 times that in the US.

数字服务已成为我们工作和日常生活中不可或缺的一部分。本文探讨了数字基础设施如何促进中国的全要素生产率（TFP）和劳动生产率。利用2003年至2019年各种层次和细节的多样化数据集，我们发现平均而言，数字基础设施投资每年对中国的TFP增长贡献了0.25至0.52个百分点。此外，我们的研究结果强调了在严重依赖数字基础设施的行业中工资显著增加的情况，显示了数字技术有利于熟练劳动力和女性工作者。与美国相比，我们发现中国在数字基础设施投资规模、年增长率和平均数字基础设施依赖度方面仍然落后，而其对中国TFP增长的贡献是美国的1.7至2.5倍。
