 note = {This paper examines the complicated interactions among innovation, imitation, market structure, and many aspects of industry performance. A central aspect of Schumpeterian competition is that some firms strive to be leaders in technological innovations, while others atempt to keep up by imitating the successesof leaders.
　Nelson and Winter constructed the simulation model of Schumpeterian competition for the first time. It is a Markov model of a single industry in which firms produce a homogeneous product and in which cost reduction through productivity improvement is the major competitive weapon.
　In the first section of the paper, the basic structure of the Nelson- Winter (NW) model is presented. Next section, the innovation and imitation process of industry by modified NW model are simulated with MapleV language.
　Being distinguished innovative firms and imitative firms in simulation run, we can explicitly analyze the behavior of productivity, output, market share and profit rate of each firm quantitatively, and price, total output, inverse of Herfindahl-Hirschman index, and average productivity of industry are evaluated for 50 periods.},
