贸易政策选择:要素流动性纬度的理论分析

Policy alternatives of agricultural trade liberalization-from the perspective of factor mobility

我国入世以后农产品贸易政策的取向成为政府、公众和学界关注的焦点。如何选择合适的贸易政策兼顾效率与公平,是一个既具有理论价值又具有实际意义的问题。本文试图从贸易理论的假设出发,从要素流动性的角度来探讨贸易政策选择的依据,分析要素流动的不充分性及其对贸易利益的影响,验证要素流动不充分时最优的贸易政策形式。

Agricultural trade policy in China has been the focus of the concerns of the government, the public and the academia since China＇ s accession to the WTO. How to choose a certain kind of trade policy which takes both allocation efficiency and social equality into account, is such a critical issue. In this paper, we attempt to provide an analysis on the choice of trade liberalization policy from the perspective of factor mobility. Beginning with querying the assumptions of classical trade theories, we found the evidence that factor immobility impacts trade benefits negatively and gradual liberalization is preferred to the Big Bang with imperfect factor mobility.
