Since the Reform and Opening-up in 1978, China has experienced a huge sustainable growth of gross domestic product (GDP) and an incredible development in Information and Communication Technology (ICT). This study aims to utilize an input-output (I-O) approach to explore the role of ICT in Chinese national economy. Specifically, we employ a static I-O framework, and analyze three topics in its application: the inter-industry linkage effect, the production inducing effect, and the supply shortage effect. We pay particular attention to the ICT manufacturing sector and ICT service-providing sector by taking the sectors as exogenous and investigating their economic impacts, respectively. The results suggest that (1) the ICT manufacturing sector has a high backward linkage effect, an intermediate forward linkage effect, a relatively low production inducing effect, and a low supply shortage effect, it suggests that ICT manufacturing sector has a powerful capacity for pulling the production activities of the whole economy. (2) The inter-industry linkage effect and supply shortage effect of ICT service-providing is low, but the production inducing effect of ICT service-providing is high, which suggests that the impact of an increase in ICT service-providing investment on the total output of all other sectors is large.
