世界主要农产品进口国进口价格弹性及关税福利损失估算

Agricultural Import Elasticity and Dead Weight Loss Estimation for Leading Agricultural Importers

本文采用Kohli(1991)的GDP最优模型,估算了世界农产品进口前20位国家318种农产品的进口价格弹性、农产品贸易限制性指数以及农产品进口关税导致的净福利损失。研究发现,一国农产品进口价格弹性与GDP大小正相关,与其发达程度则没有显著性相关关系。在多哈回合农产品贸易谈判中,我国可以在自身农产品市场不断开放的基础上,提高对印度、印度尼西亚、韩国、墨西哥和泰国等主要出口市场的要价。

Applying Kohli＇ s （1991） GDP maximization model, this paper es- timates the import price elasticity of 318 HS 6-digit agricultural products import- ed by 20 leading agricultural importers in the world. Also calculated in this pa- per are Agricultural Trade Restrictiveness Index and Dead Weight Loss resulted from agricultural import tariff for each country. This research suggests that agri- cultural import elasticity of a country is positively correlated with its GDP, while the correlation of this elasticity with GDP per capita is not significant. In the Do- ha Round, this paper suggests, China is supposed to further open its domestic market and may raise its offer to its major exporting markets such as India, Indo- nesia, South Korea, Mexico and Thailand.
