摘要： With the growth of the global population and the surge in demand for animal protein, the production of animal feed has increased rapidly. This trend is expected to continue in the future. According to a report by Fortune Business Insights, the compound annual growth rate (CAGR) of global animal protein demand is projected to reach 4.49% from 2023 to 2030. However, environmental issues such as air and water pollution resulting from the feed processing industry are becoming increasingly prominent. To address these environmental challenges, intensive production methods and industrial clustering have been proposed as viable solutions. These strategies can enhance production efficiency and mitigate environmental pollution. Nonetheless, the spatial separation between upstream feed crop cultivation and downstream livestock farming, particularly in China, poses significant challenges to the development of industrial clustering. Therefore, this study investigates the spatial agglomeration patterns of China's feed processing industry, examines its geographical connection with upstream and downstream industries, and analyzes the factors driving these patterns. This study treats the feed processing industry as an independent intermediate link and offers new insights into the pollution management implications arising from the decoupling of feed crop cultivation and livestock farming. The findings reveal that, over the past two decades, China's feed processing industry has primarily concentrated in the coastal regions of East and South China, with an increasing concentration in these areas. The spatial distribution of the industry is influenced by a variety of factors. The impact of upstream raw material supply on feed processing industry is largely reflected in international imports. Downstream demand for livestock and poultry farming not only directly drives the local agglomeration of feed processing industry but also affects neighboring regions. In terms of transportation, road transport, which facilitates "door-to-door" delivery of feed, has a significantly positive impact on local agglomeration. In contrast, rail and inland river transport, due to cost limitations, suppress agglomeration in neighboring regions. Furthermore, factors such as land rent and corn temporary storage policy influence industrial clustering by affecting production costs. However, due to data availability constraints, this study does not incorporate factors such as climate and technological advancements, which warrant further exploration and refinement in future research.
