摘　　要：笔者采用广义超越对数成本函数确定效应模型和SUR法,对山西省15个县市的44家果蔬农民专业合作社的规模经济和范围经济进行了实证研究。结果显示,样本合作社总体上具有轻微的规模经济和显著的范围经济。样本合作社产出的主产品、化肥和农膜具有特定产品规模经济;主产品和化肥的联合生产相对其他产品的联合更具有特定产品范围经济。合作社产出的主产品、化肥和农膜具有较大优势,合作社可以通过增加主产品销售、提供统购化肥和农膜的服务,使其投入成本的增加小于产出的增加,进而实现规模经济和范围经济。The paper researches the economies of scale and scope of 44 fruit and vegetable cooperatives in Shanxi Province by using SUR method and the fixed period generalized translog cost model. It is found that the cooperatives have slight economies of scale and significant economies of scope as a whole ; the outputs of main products, fertilizer and agricultural films have product-specific economies of scale which means by increasing these inputs would decrease the total cost in long run. The main products joints with chemical have product-specific economies of scope, which their joints would save more cost than other outputs joints. Therefore, the output of main production, fertilizer and agricultural films have larger advantage, which could make the the proportion of outputs cost less than the cost of inputs and therefore achieve the economies of scale and scope of the cooperatives.
