[Purpose/Significance] This study aims to unravel the complex relationship between new quality productivity (NQP) and rural revitalization, and to deepen understanding of the role of media in rural development. NQP, characterized by advanced technologies, innovative practice, and enhanced efficiency, has the potential to transform rural economies and communities. This research provides a multi-dimensional theoretical perspective and scientific foundation to advance comprehensive rural revitalization in China. By offering novel insights compared to the existing literature, this study establishes its significance in the field of scientific knowledge and demonstrates its potential to address significant real-world challenges. Understanding the synergies between NQP and rural revitalization can help policy makers, researchers, and practitioners to develop effective strategies to promote sustainable rural development and address socio-economic disparities. [Method/Process] The study employed a rigorous methodological approach that involved the training of a naive Bayes classifier to categorize the texts of government work reports. This machine learning technique enabled the extraction and analysis of relevant information from a large corpus of textual data, providing a robust basis for further empirical investigation. The study utilized provincial-level data from 2012 to 2022 to construct comprehensive evaluation frameworks for the NQP and rural revitalization. These frameworks included a wide range of indicators reflecting economic, social, and technological dimensions.Statistical analyses included bi-directional fixed effect models and spatial Durbin models, which allowed for a comprehensive exploration of the impact mechanisms and spatio-temporal dynamics of NQP on rural revitalization. The bi-directional fixed effect model helped to control for unobserved heterogeneity and to capture the dynamic interplay between NQP and rural revitalization over time. The spatial Durbin model was particularly useful in identifying spatial spillovers and understanding regional interdependencies. The theoretical underpinnings of this research were grounded in established frameworks in economic development and media studies. Media practice, including information dissemination, community building, and consumption upgrading, were hypothesized to play a crucial role in facilitating the impact of the NQP on rural revitalization. The empirical foundations were derived from robust provincial-level datasets, ensuring the reliability and validity of the findings. These methodological choices ensured a rigorous examination of the complex dynamics between NQP and rural revitalization in different regions over time. [Results/Conclusions] 1) Media factors demonstrated significant complementary relationships with various drivers of rural revitalization. 2) Media practice, centered on information support, community building, and consumption upgrading, has profoundly altered rural production relations and economic bases. 3) Temporally, both NQP levels and rural revitalization showed rapid growth, with annual growth rates increasing. Spatially, the central and western regions showed a stronger impact of NQP on rural revitalization compared to the eastern regions.4) NQP had significant spatial spillover effects on rural revitalization, not only influencing local revitalization efforts but also fostering stronger indirect effects on surrounding areas, thereby promoting regional interlinked development.

Simple Summary: This study investigated whether COS in the diet can improve the digestion and rumen health of beef cattle under in vitro fermentation conditions. A total of 24 fermentation tanks were randomly allocated into four groups. Each treatment had six replicates, with one tank per replicate. Each group received a different concentration of 0.02% COS, 0.04% COS, 0.08% COS, and a control group (CON). The results demonstrated that the addition of COS facilitates a shift in rumen fermentation from the acetate model to the propionate model. This is achieved by influencing the microbial population, resulting in alterations to the fermentation level, nutrient disappearance rate, and gas production. These changes have the potential to enhance rumen health. The study aimed to investigate the effect of dietary chitosan oligosaccharides (COS) meal levels on the nutrient disappearance rate, rumen fermentation, and microflora of beef cattle in vitro. A total of 24 fermentation tanks were randomly divided into four treatments containing 0% COS (CON), 0.02% COS, 0.04% COS, and 0.08% COS for an 8-day experiment period, with each treatment comprising six replicates. The disappear rates of DM, CP, EE, and total gas production were quadratically increased with increasing COS levels. The disappear rates of DM, CP, EE, and ADF were greatest, whereas the total gas production was lowest in the 0.08% COS group. The pH, NH3-N, MCP, the content of propionate, isobutyrate, butyrate, valerate, and the A/P were quadratically increased with increasing COS levels, while the A/P were linearly decreased. The pH, MCP, and the content of propionate, and butyrate were highest, whereas the NH3-N and the content of acetate, isobutyrate, valerate, and the A/P were lowest in the 0.08% COS group. Microbiomics analysis showed that the rumen microbial diversity was not altered between the CON and the 0.08% COS group. However, the relative abundance of Methanosphaera, Ruminococcus, Endomicrobium, and Eubacterium groups was increased, and the relative abundance of pathogenic bacteria Dorea and Escherichia-Shigella showed a decrease in the 0.08% COS group. Overall, the 0.08% COS was the most effective among the three addition levels, resulting in an increase in the disappearance rate of in vitro fermented nutrients and improvements in rumen fermentation indexes and microbial communities. This, in turn, led to the maintenance of rumen health. [ABSTRACT FROM AUTHOR]
