This letter defines seven useful measures for directed complex network analysis. Since each node in the directed network is with an in-degree and an out-degree, and each arc is directed, one node-based in-out degree correlation measure and four arcbased degree-degree correlation measures (i.e., in-in, in-out, out-in, out-out) are defined. Similarly, two clustering coefficient measures are defined for the directed network, i.e., in-clustering coefficient and out-clustering coefficient. Finally, we use these measures to analysis the world trade network. ? 2011 ISSN 2185-2766.
