Abstract: Based on the data of Chinese industrial firms，this paper examines how standardization affects R&D intensityTheoretically，standardization can both enable and constrain innovationHowever，this paper finds that standardization in China significantly enhances the R&D intensity of industrial firmsFurther analysis shows that，standardformulating activities of firms themselves have larger positive impacts on R&D intensity，and these influences are stronger in larger firms and nonstateowned enterprisesMoreover，this paper also finds that standardformulating firms mutually constrain each others R&D，but this effect is not statistically significant
