摘要：在传播技术迅猛发展的今天，传媒生态发生了天翻地覆的变化，移动互联网升级换代不断加速、智能终端产品层出不穷，移动新媒体的崛起正在悄然改变着我们的生活方式和社会结构。移动新媒体在更便捷地服务社会大众信息生活的同时，根植于社会阶层差异的“知识沟”，也在一定程度上加剧着社会的撕裂，形成了不同社会阶层间新的“数字鸿沟”，阻碍经济的持续健康发展，也严重影响着社会和谐有序局面的实现。透析移动新媒体的发展形势及其现实影响，阐释“知识沟”假设的基本原理及其新的发展迹象，论证移动新媒体环境下“知识沟”的平衡策略是本文的核心内容。50104

Research on "Knowledge Gap" and User's Accessibility in New Media Environment

Abstract: As the rapid development of communication technology, media ecology has tremendous changes. Mobile internet continues to upgrade and update increasingly and smart terminal products emerge in endlessly. The rise of mobile new media is quietly changing our way of life and social structure. While mobile new media services information life of public more convenient, the “knowledge gap” which rooted in the social stratification is also exacerbating the tear of the society in a way, and formed the new “digital gap” between the different social classes. As a result, it will impede the sustainable and healthy of economic development, and impacting the social harmony seriously. The core content of this paper is that: Analyzing the development trend of the mobile new media and its practical influence; explaining the basic principles of the “knowledge gap” hypothesis and its new development signs; and demonstrating the equilibrium strategies of “knowledge gap” under the mobile new media environment.
