摘　　要：为优化农产品物流中心经营规模,分析了农产品物流中心的经营行为,将规模收益率引入物流中心经营规模优化中,建立了一种基于生产函数和规模收益率的物流中心经济规模优化模型,计算了物流中心经营规模与规模收益率的关系。以寿光市农产品物流中心为例,对优化模型进行了应用,规模收益率计算结果在模型确定的范围内,且随物流中心资本与劳动力投入的增长,物流中心规模收益率呈现先递增后递减的特征,结果表明优化模型是可行的,可以用来衡量物流中心经营规模的经济性。In order to optimize the economic scale of agricultural products logistics center, its production function, scale profit ratio and economic behavior were analyzed, and the relation of scale profit ratio and logistics center scale was calculated. Shouguang logistics center of agricultural products was taken as an example to validate the optimized model. Calculation result shows that the scale profit ratio is in the determination scope of the model, it begins to increase with the growing of labor and capital investments, and then to decrease with the continuous growing, which indicates that the optimized model is feasible, can be used to evaluate economic property of the operational scale of logistics center. 2 tabs, 2 figs, 12 refs.
