The spatial pattern of innovative input in the urban agglomeration is the comprehensive reflection of innovation function division among cities in urban agglomerations, which affects its overall innovation performance profoundly. Thus, this paper took the six urban agglomerations, applied urban Gini coefficient and urban primacy index, calculated the spatial pattern and evolution trend of their innovation input, analyzed the equilibrium relationship and causality between urban agglomeration overall innovation performance and innovation input spatial pattern by panel co-integration, and drew th...
