英文文献作者：Liu, Karen
英文文献摘要：
The purpose of this paper is to resolve conceptual problems in the crop supply component of the present GOL model and to develop the conceptual framework for a multiple-product production system of a multiple -commodity agricultural trade model. The major emphasis on the revision of the crop supply system is structural consistency in order to assure consistent acreage allocation among crops and to impose total arable land area constraints on supply.
