媒介的新发展带来讯息传播格局的重大变化，尤其是对传统电视媒体造成巨大冲击。电视新闻作为电视媒体的主要生产内容之一，面对新的传播生态，也必将及时做出调整甚至转型，方能即保持自身的公信力又具备广泛的社会影响力。新闻传播是一门实践性非常强的学科，本文选取从电视新闻这个小角度入手，探讨在媒介发展融合的大背景下，电视新闻如何与之相适应的切实可行的具体“战术”打法：在多屏传播时代，电视新闻的生产及传播的过程中,如何最大限度地利用新兴的网络社交平台及通信新技术与受众互动，以达到互动功能的全方位提升；同时关注如何利用好电视媒体在传播过程产生的大数据资源，使传播内容和传播方式更加有的放矢，并由此促使电视新闻内容生产流程的升级再造，以适应其在不同平台、不同终端的广泛传播。用优质内容打造自身不可复制的核心竞争力，使电视新闻的生产内容更适合在新的媒介生态下生存并传播，从而增强电视新闻的核心竞争力和社会影响力。

New development in medium has brought forth a dynamic change in the landscape of news dissemination，creating a great impact on traditional television media. Being placed in such a new medium ecology, television news, as the main content produced by television media, must also adapt and even transform itself to remain credible and also exert a wide social impact. News dissemination is a subject that relies heavily on practice. This thesis takes television news as an entry point and explores how television news can, against the backdrop of media convergence, cope with the new reality using an adapted and viable “strategy”: in an era of multi-screen broadcasting, how television news production and dissemination can maximize the use of emerging social media platforms and new communication technologies to improve interaction with the audience. In the meantime, the thesis also illustrates how big data produced in news dissemination can be best put to use and make both the content and approach of dissemination more targeted. This will in turn induce the television news production process to reinvent itself, making it better suited for broadcasting on different platforms and devices. Content of quality renders an irreplicable core competitiveness to television news, helping it better survive and broadcast in the new medium ecology, thus promoting the core competitiveness and social impact of television news.
