规模经济问题既存在于农业生产的数量上，也存在于农业生产的质量上。从生产成本的角度出发，构建农产品质量成本函数及其弹性估计模型，并对中国乳制品行业的质量成本模型进行实证检验。对调查数据、原料奶质量-成本弹性和数量-成本弹性的估算结果分析表明，在当前的要素市场和政策环境下，原料奶质量不存在规模经济，提高原料奶质量的经济激励不足。相比之下，原料奶数量表现出规模经济，增加生产规模是有利可图的。这为解释为什么提高原料奶质量比增加原料奶数量困难得多提供了理论依据。因此，要从根本上提高原料奶的整体质量水平，改变规模不经济的现状应是首要策略。(C) 2014爱思唯尔公司版权所有。
The issue of economy of scale exists both in terms of the quantity of agricultural production and also in its quality aspect. From the perspective of production cost, we build an agrifood quality-cost function and its elasticity estimation model and then empirically estimate this model in China's dairy industry. Analysis of survey data, estimation results of raw milk quality-cost elasticity and quantity-cost elasticity indicate that, in current factors market and under current policy environment, an economy of scale for raw milk quality does not exist and the economic incentive to improve raw milk quality is not enough. In contrast, raw milk quantity exhibits an economy of scale, and increasing the production scale is profitable. This provides a theoretical basis for explaining why improving raw milk quality is much more difficult than increasing quantity. Accordingly, in order to fundamentally improve the overall level of quality of raw milk, changing the status of diseconomy of scale should be the primary strategy. (C) 2014 Elsevier Inc.
