Based on the patent data and stock return rates of thousands of China listed companies (A-shares), the effect of the innovation continuity which representing by the patent publication frequency, on the stock return rate were analyzed via ANOVA. The innovation continuity was good for observing the stock return rate in the whole market, Shanghai main board and small-medium board. The A-shares with the stronger innovation continuity showed the higher stock return rate. The utility model grantís innovation continuity was an indicator of the highest applicability. It could be applied for the whole market and any stock board. The design grantís strongest innovation continuity group had the highest stock return rate mean among all patent speciesí strongest innovation continuity groups 5 though the design grant was usually regarded as the most valueless patent species in China. The invention grant was always regarded as the most valuable patent species around the world, yet the stock return rate variance between the strongest innovation continuity groups of the invention grant and the invention publication was not significantly different. The invention publicationís innovation continuity was more recommended rather than the invention grantís innovation continuity.
