Improving the capacity of urban technological innovation is the only way to develop urban economy and improve national innovation capacity. The study of the impact of a variety of industrial clustering model on urban technological innovation has a very practical significance for improving the urban competitiveness based on characteristics of industrial agglomeration in China´s cities. From the perspective of the technology spillover effect of the different industrial agglomeration mode, we select the prefecture-level cities of 23 provinces in China from 2007 to 2009 and use empirical analysis to find out how the mechanism of diversify promote the city´s technological innovation and its relative contribution to technological innovation in the city theoretically and empirically.
