Abstract: Since the 21st century,the development of ICT has deeply influenced China's economy and society. To test whether there is a "productivity paradox" for China's ICT capital, the PIM is used to estimate the capital stock and output elasticity of ICT service industry and non-ICT service industry at boththe national and regional levels from 2003 to 2016. The results show that China's ICT service industry existed obvious "underinvestment",but later eased since 2012. The capital stock of ICT service industry showed unbalanced distribution among different regions,but the gap between the capital stock of ICT service industry among different regions tended to converge. Investment in ICT service industry can significantly promote economic growth, and the output elasticity for ICT service capital was between 0.1605 and 0.1705. From the perspective of time trend,the impact of ICT service industry capital on economic growth was continuously enhanced during the investigation period. From the perspective of regional differences, the output elasticity of ICT service industry capital decreasedfrom the east, middle and west in sequence. It is further confirmed that there is no "productivity paradox" for China's ICTaradox

Key words: digital China, ICT service industry, capital stock, output elasticity, productivity paradox
