DISTRIBUTION OF PRODUCER SIZE IN GLOBALIZED MARKET

Distribution of producer size in a globalized market is a complex market phenomena, which is affected by the market behavior of consumers such as the loyalty of consumers to producers and the purchasing power of consumers, as well as the trade barriers among countries. In the present paper, in order to study the distribution of producer size in the globalized market, we construct a bipartite network that consists of consumers and producers with community structure. We find that the distribution of producer size in each community in a multi-community network can be projected to that in one-community bipartite network by mapping the globalized market behavior of consumers to an isolated market behavior. The mapped market behavior is dependent on the trade barriers among communities. The distribution of producer size in globalized market is thereby dependent on the mapped loyalty of consumers and the mapped growing rate of purchasing power. Furthermore, simulation results show that the distribution of producer size differs community by community. It follows the power-law distribution if both the mapped loyalty of consumers and growing rate are high.
