The relationship between variety and economic growth has been paid much attention in the academic. This paper uses Gini specialization index and entropy measurement method to measure the level of specialization and variety of Chinese cities, and use the concept of “proximity” proposed by Hidalgo to divide the related variety and unrelated variety. Using the panel data of 252 prefecture-level cities in China from 2001 to 2011, we attempt to explore the relationship between specialization, variety and urban economic growth. The empirical results show that the specialization has a negative effect on the urban economic growth, while the variety has an obvious positive influence. Related variety has a positive correlation with urban economic growth, while unrelated variety is not conductive to urban economic growth. Specifically, the impact of specialization and variety on urban economic growth has obvious regional differences. Variety only contributes to the economic growth of the eastern and central cities; related variety and unrelated variety both have an impact on the urban economic growth in the eastern, central and western cities, but the promotion on the eastern cities is stronger than that on the central and western cities.
