This paper applies PEST analysis to The Chinese version of TikTok, a video-sharing app developed by Zhang Yiming-He and founded in 2016. It examines how TikTok has adapted to different market conditions over time using PEST and SWOT analyses. This paper will provide critical insights into how The Chinese version of TikTok has developed from the perspective of the company's top management team in light of changes within the market since its establishment to help them make decisions about their strategy going forward. It will also look at changes in social behavior over time to explain their resilience. The PEST study of the Chinese version of TikTok reveals that the political paradigm of the technical element, which includes the AI big data algorithms and the AI economic calculation model, can stimulate public interest because it is a content platform. As a result of its monopolistic nature, however, it is motivated by a desire to serve the public interest. PAFBJR-301001 can see the opportunities that arise from these problems, but the benefits of technological advances are less noticeable. According to the SWOT analysis, five main advantages stem from the technical aspects. First, it has a vast user volume, which means it has acquired many data on user behavior. Second, it has powerful Big Data-based financial debugging skills. Third, it has access to cutting-edge artificial intelligence tools and data. In the fourth place, it has created an advertiser-friendly platform. As the last step, it has established a public service-oriented website. Because it relies on Big Data, AI's technical flaws—including its flawed big data algorithms and extremely conservative economic calculating model—are greatly relieved because it relies on Big Data. Business choices under a centralized economic paradigm have to be made at the top, reducing room for creativity. Another flaw is that there is no internal mechanism for The Chinese version of TikTok to adapt to changing circumstances or industry trends. The AI big data algorithms and the AI economic calculation model face competition from other participants in this industry who may have access to a more comprehensive database and superior artificial intelligence equipment.
