Based on annual pork yield of each province in 1996-2014, using Gini coefficient and spatial polarization index model, empirical analysis was carried out for spatial imbalance and polarization degree of swine production distribution. Results indicate that there is high imbalance in spatial distribution of swine production. The imbalance takes on first rise then declines with fluctuation, largely because of inter-group gap. From the perspective of regions, the regions with balanced grain production have the highest imbalance in swine production, followed by main sales regions, and the main grain production regions have the lowest imbalance. The polarization index indicates that the overall polarization degree of the spatial distribution of swine production takes on a growing trend, and that of each functional region of grain production is also growing.
