The results showed, firstly, the unofficial news websites and microblogs enjoy high usage frequency; secondly, media contact can influence the satisfaction degree of motivation for media use and the gratification with news Apps; thirdly, there is a positive correlation between the satisfaction degree of motivation for media use and media gratification. In order to enhance users' gratification, dependency on and loyalty to the news media, it is necessary to strengthen the content customization for the information motivation, improve the information gathering for the convenience motivation, focus on the user generation for the entertainment motivation, pursue the organic integration of socialization, localization and mobility for the social motivation, and then create mobile news Apps with brand characteristics.
