A gravity model analysis of meat trade policies
改进了传统引力模型用于单一农产品，分析影响肉类贸易流量的因素，发现贸易政策、补贴、生产能力和距离是关键，长期协议促进贸易，进口配额和口蹄疫则阻碍贸易。
Abstract The conventional gravity model is revised for a single commodity and applied to meat markets to determine factors affecting trade flows of meat. This study demonstrates that the gravity model for a single agricultural commodity can be parameterized more effectively by using time series and cross‐section data rather than cross‐section data alone. This study reveals that trade policies and subsidies used by exporting and importing countries, livestock production capacity in countries, and distances play an important role in determining trade flows of meat. Long‐term agreements achieve the highest performance toward enhancing international meat trade. Import quotas and the hoof‐and‐mouth disease on beef greatly impair meat trade.
