內(nèi)容簡(jiǎn)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.
數(shù)字服務(wù)已成為我們工作和日常生活中不可或缺的一部分。本文探討了數(shù)字基礎(chǔ)設(shè)施如何促進(jìn)中國(guó)的全要素生產(chǎn)率（TFP）和勞動(dòng)生產(chǎn)率。利用2003年至2019年各種層次和細(xì)節(jié)的多樣化數(shù)據(jù)集，我們發(fā)現(xiàn)平均而言，數(shù)字基礎(chǔ)設(shè)施投資每年對(duì)中國(guó)的TFP增長(zhǎng)貢獻(xiàn)了0.25至0.52個(gè)百分點(diǎn)。此外，我們的研究結(jié)果強(qiáng)調(diào)了在嚴(yán)重依賴(lài)數(shù)字基礎(chǔ)設(shè)施的行業(yè)中工資顯著增加的情況，顯示了數(shù)字技術(shù)有利于熟練勞動(dòng)力和女性工作者。與美國(guó)相比，我們發(fā)現(xiàn)中國(guó)在數(shù)字基礎(chǔ)設(shè)施投資規(guī)模、年增長(zhǎng)率和平均數(shù)字基礎(chǔ)設(shè)施依賴(lài)度方面仍然落后，而其對(duì)中國(guó)TFP增長(zhǎng)的貢獻(xiàn)是美國(guó)的1.7至2.5倍。
