新冠肺炎疫情期间，国内公益广告呈现出多层次的广告传播主体、全方位立体化的发布载体、丰富的广告内容、以情感诉求为主的共情传播等创新特色，广告效果有所提升。结合已有的传播经验，今后，突发公共卫生事件中的公益广告传播应进一步充分洞察受众需求，挖掘民族文化特质，汇聚社会智力，发挥渠道联动效益，融入新技术，最大化传播价值。

During COVID-19, domestic public service advertising presented innovative features such as multi-level release subjects, three-dimensional carriers, relatively rich contents and focusing on emotional appeal to realize the effect of empathy. The advertising effect has improved. Combined with the existing communication experience, in the future, public service advertising communication in public health emergencies should further understand the needs of the audience, tap the national cultural characteristics, gather social intelligence, bring into play the benefits of channel linkage, integrate new technologies and maximize the communication value.
