网络空间是亿万民众共同的精神家园，更是意识形态交锋的无形场域。习近平总书记指出：“互联网日益成为意识形态斗争的主阵地、主战场、最前沿”。[1]这一重大论断揭示了新时代意识形态安全的关键命题——谁掌握了网络空间主导权，谁就掌握了价值塑造和思想引领的更高点。而新时代背景下，随着人工智能、大数据、元宇宙等技术的加速迭代，在重塑信息传播范式的同时，也为意识形态安全带来了新的风险，其不仅关系国家的政治安全和社会稳定，更关系国家的文化软实力和国际竞争力。鉴于此，深入剖析新时代网络意识形态面临的问题与挑战，准确把握其内在规律和发展趋势，并据此提出科学有效的防范策略，成为当前意识形态安全领域亟待解决的重要课题。

The cyberspace serves as a shared spiritual home for hundreds of millions of people and an intangible battlefield for ideological confrontations. General Secretary Xi Jinping pointed out that the internet has increasingly become the main position, main battlefield, and foremost frontier of ideological struggles. This major judgment reveals the core proposition of ideological security in the new era: whoever secures the dominant power of cyberspace will gain the initiative in value shaping and ideological guidance. In the context of the new era, the accelerated iteration of emerging technologies such as artificial intelligence, big data, and the metaverse has reshaped the paradigm of information communication, while bringing new risks to national network ideological security. These risks are not only related to China’s political security and social stability, but also bear on the country’s cultural soft power and international competitiveness. Therefore, thoroughly analyzing the problems and challenges facing network ideology in the new era, accurately grasping its internal laws and development trends, and formulating scientific and effective prevention strategies have become urgent and vital tasks in the field of current ideological security research.
