With the rising concern of Tik Tok videos propagating misinformation to younger viewers, research on the adversary effects of the platform of Tik Tok has been few and far between. This research applies a simplistic approach of gathering and observing numbers related to 60 content creators on YouTube and Tik Tok (30 on each platform) for the comparative analysis. The analysis is largely built upon the average video length of each creator’s most recent 50 videos and the frequency of numbers of lines of each top comment. The correlation between the two is found relatively weak within one platform. However, videos on YouTube have significant lengthier top comments than those on Tik Tok most of the time, which suggests a higher level of thinking and commitment on the former in general. The two factors along with different features on the two platforms that are tailored towards different types of audiences contribute to the levels of discussion and the ways users treat information and misinformation. Implications and recommendations in regard to Tik Tok’s environment are further discussed.

By mastering the spatial-temporal evolution of patterns of soybean production, a reference for optimizing a soybean production layout could be provided, ensuring food security. The variation coefficient method, and the comparative advantage and spatial autocorrelation models were used to analyze the spatial divergence regularities of soybean production, sown area and yield, spatial-temporal changes in the comparative advantages of soybean planting efficiency and soybean planting scale, and the spatial agglomeration characteristics in China from 1949 to 2019. The results indicate that (1) from 1949 to 2019, soybean production and yield changes in China remained constant with a fluctuating upwards trend, and soybean sown areas hardly changed, yet experienced a sharp fluctuation. (2) The Northeast China Plain (NECP) was the main soybean-producing area, and its main position was strengthened. In contrast, the main soybean production position of the Huang-Huai-Hai Plain (HHHP) has declined. The Northern arid and semiarid region (NASR), the Sichuan Basin and surrounding areas (SBSR), the Middle-Lower Yangtze Plain (MLYP), and the Yunnan-Guizhou Plateau (YGP) became new soybean production growth poles. (3) The spatial distribution of soybean planting efficiency-related comparative advantages in China extended from northern China to the whole country, and the soybean planting scale-related comparative advantages proceeded through three stages: steady expansion, relative stability, contraction, and stabilization. (4) The spatial agglomeration of soybean planting efficiency-related comparative advantages has weakened, and the spatial agglomeration of the soybean planting scale-related comparative advantages exhibited a strengthening-weakening-strengthening-weakening process. Through our research analysis, we propose a policy resource to fully utilize the soybean planting efficiency-related comparative advantages in southern China (SC), promote grain-soybean rotation patterns in the HHHP and NECP, improve the soybean cultivation subsidy system, and build a soybean industry chain in the NECP.
