Taking the number of patents as variables and using the methods of the weighted with both GDP and population, the paper examines the differences of urban innovation capacity in Guangdong Province based on the Theil index. It shows that the urban innovation capacity differences are reduced by the weighted with GDP, and enlarged by the weighted with population; cities are taking more and more attention to the construction of urban innovation, by which they develop themselves; the population growth rate has certain relevance with the city innovation ability, which is the main reason of the urban innovation ability differences.
