摘要
Abstract
As a major agricultural country,the agricultural policies of the United States not only exert influences on global agricultural commodity trade but also offer insights for the development of agriculture in other countries.Adopting a textual analysis approach,this study employs statistical analysis and the Latent Dirichlet Allocation(LDA)model to identify the key policy concerns embedded in the United States Department of Agriculture(USDA)media release data from 2012 to 2023.The findings indicate that U.S.agricultural policies manifest in various domains as follows:a market orientation that prioritizes efficiency yet lacks equity;a robust drive for technological innovation coupled with emerging risks;an emphasis on environmental protection that confronts significant challenges;and a comprehensive approach to rural development that reveals existing disparities.关键词
