In recent years, the development of China's short video market has become a blowout trend. The goal of digitalization to achieve social cultural development shows that people's good life is closely related to short videos. This paper aims to achieve the goal of digital social cultural development, study the generation and protection of government short videos, and explore the impact of government short videos on the public. For the production of government short films, this paper divides them into three dimensions: sense of achievement, sense of happiness and sense of security. In these three dimensions, nine official bean print accounts with more than 100000 bean print fans were selected as the research object, and the factors affecting the transmission effect of short videos were discussed with the number of likes, views, forwarding and comments as dependent variables. For the protection of short video, four protection measures are proposed according to the influencing factors. The experimental results of this paper show that the subject, role and style of government short films account for 29.8%, 24.6% and 21.3% respectively, which shows that the production of government short films should focus on the subject, participating role and style of short films.
