 note = {When we refer to economic theory of information, it includes how uncertainty affects decision making, what characteristics information goods have what information activities are, what kind of effects information sectors have, and so on.
　In this paper, we examine the characteristics of information goods (invisible, easy to be conveyed, able to be copied with lower cost, individable in supplying and consuming, hard to be priced).
　Then we especially focus on R&D at firm as an internal information activity, dealing with the problems such as why R&D activity is done within an organization and whether R&D output can share the same characteristics of ordinary information goods or not.
　In addition, we discuss difficulty in evaluating R&D output which is an information "input" for the production sector of the same firm and management of R&D projects they are engaged in simultaneously.},
