Analysis of Network Effect in Port and Shipping System Characterized by Scale-free Network

摘要

Based on the brief summarization of the development, properties and representative research achievements of scale-free networks, the paper makes an empirical analysis in some complex network characteristics of global shipping lines network. Taking port as dominant products, and shipping service, its complementary products, the mechanism of network effect in products system is analyzedby the study of two-stage budgeting procedure.
