This paper investigates the demand2side effect of income inequality on economic growth. Income inequality can be measured by the population share of the rural residents and their relative income. Economic growth is represented by quality improvement driven by innovations of monopolistic firms. Since rich consumers are more willing to pay high prices for the better quality than the poor, the firms profit depends on the income disparity of consumers1 At the separating equilibrium, goods of different quality levels are sold to different consumers. A higher relative income of the urban residents is good for innovations, but a larger population share of the rural residents is bad for innovations. Our empirical evidence supports our theoretical prediction. Key Words : Inequality ; Urban2rural Disparity ; Urbanization ; Economic Growth JEL Classification :D31, D43, O12, O15 ( : ) ( : ) 29
