ab: Summary: Japanese inter-firm network which consists of about one million
    firms and four million directed links is analyzed by evaluating
    PageRank, and the authority and hub scores of HITS. We show scale-free
    degree distribution, power-law distribution of firm-size, fat-tailed
    distribution of growth rate, positive correlation between degree and
    firm-size, and similarities between degree and these scores. By
    comparing with randomized networks, we find that (i) the firm with
    large firm-size tends to have large PageRank, and small authority and
    hub scores, and (ii) PageRank correlates significantly with the growth
    rate which is hardly observed with other quantities.
