    "abstract": "The Japanese shareholding network existing at the end of March 2002 is\nstudied empirically. The network is constructed from 2,303 listed companies and\n53 non-listed financial institutions. We consider this network as a directed\ngraph by drawing edges from shareholders to stock corporations. The lengths of\nthe shareholder lists vary with the companies, and the most comprehensive lists\ncontain the top 30 shareholders. Consequently, the distribution of incoming\nedges has an upper bound, while that of outgoing edges has no bound. The\ndistribution of outgoing degrees is well explained by the power law function\nwith an exponential tail. The exponent in the power law range is gamma=1.7. To\nunderstand these features from the viewpoint of a company\u0027s growth, we consider\nthe correlations between the outgoing degree and the company\u0027s age, profit, and\ntotal assets.",
