Based on Schumpeter’s Innovation Theory，Rogers’s innovation diffusion theory and integrated innovation theory，this paper constructs the New Media Innovation Index of mobile APP，which includes 3 primary indicators such as Media Quality，Technology Attribute and User Value，and six secondary indicators，16 3-level indicators. According to the New Media Innovation Index system，we take a quantitative study on New Media Innovation level of the selected 7 kinds of 106 mobile APP. The results show that Instant Messenger and social mobile APP had an impressive showing，Mobile Live APP take a sudden emergence，payment and information APP need to upgrade. The “Media Quality” and “User Value” indicators score is higher as a whole and relatively balanced，“Technological Attribute” indicators on the low side and polarization. Based on the results of the New Media Innovation presented by the study results，the mobile APP should take the content construction as the core，take the technology as the engine，take the user demand as the leading factor，and enhance the overall level of New Media Innovation.
