Urban growth is considered to be driven by the four kind of factors (population growth, increase of income, decrease of commuting cost and agricultural land rent) in the standard monocentric model. With the development of technology, urban innovation may boost urban land demand and lead to more dispersed urban morphology in developing countries such as China. However, to our best knowledge, there are few of studies examining this effect of urban innovation on urban land growth. This paper studies the extent to which urban growth is driven by urban innovation, and whether urban landscapes are more scattered when the cities are more innovative. We construct a panel dataset by using existing statistical data from 2007 to 2017 and spatial data source at two time points (2010 and 2015) for 231 Chinese cities. Two fixed effects models are employed to control for the possible correlation between independent variables and unobservable city-level effects. The results suggest that urban innovation has indeed driven up urban land growth and make the urban landscape more scattered. We test the robustness of our results using alternative measures of urban innovation, and the main results remain robust. Our empirical evidence has important implications for policy making.
