The effect of corporate innovation on market structure was analyzed in a two-equation model incorporating variables such as concentration ratio and intensities of research and development, advertising and capital. The data analyzed were taken from a Small Business Administration database which reported on 8074 innovations introduced in 1990. It was concluded that innovativeness is an endogenous factor which may restructure markets into industry concentrations.
