Abstract

Pig farming significantly impacts environmental and human health due to nitrogen (N) losses, particularly ammonia (NH3) emissions, especially in regions with high concentration of pig production. In China, national policies regulate the spatial distribution of pig farming, leading to regional variations that influence product distribution and environmental outcomes. However, our understanding of how regional policy responses affect N emissions and the associated socioeconomic costs of pig production remains limited.
