The Japanese government decided to promote “smart society” in the 5th Science and Technology Basic Plan. The purpose of this research is to evaluate the effects of information and communication technology (ICT) in smart society by input-output analysis using the food industry and agriculture as examples. We define food production and agricultural activities utilizing ICT as a smart food-agri system, and try to analyze the effect of such a system on the economy as a whole. As a result, we confirmed that such a system has a large economic ripple effect on information sectors. At the same time, through these analyses, (1) we redefine information goods and service sectors, (2) we describe the new management sectors that are using these goods and services, but are not currently independent businesses, and (3) we clarify new industrial structure that exists in “smart society” using ICT.
