In recent years, with the computer technology network communication technology and constant innovation rapid development of digital technology, digital new media got rapid development. Under the digital new media industry has gradually become the core industry of 21 st century knowledge economy and the new economic growth point. But there are still some problems in the digital of new media development. How to treat these problems to take effective countermeasures is vital to healthy development of the new media. Our research proposes corresponding guidance and the perspective on the development orientation which acts as the paradigm and the guideline.展开更多
