Abstract: This paper proposed an evolutionary model of industrial dynamics based on NW model.It described firms’ product competition.And the competing dynamics in the industry,which allows new firms’ continuous and random entry,could be analyzed by using the model.The paper studied the evolution of industry structure and the interaction between firms’ investment decision-making,R&D strategies,technology transformation,product innovation as well as other aspects of industry characteristics.The evolution of industrial structure was simulated by computer experiment,and the simulation showed that the model could make reappearance of the stylized facts in the evolution of the industrial that produces and sells heterogeneous product.

Key words: evolutionary economics, industrial structure, innovation and imitation
