农产品价值增值的中间商决策及影响因素

The Value-added Decisions and Influencing Factors of the Middlemen on the Agricultural Products

为提高我国农产品流通环节价值增值水平,保障农产品质量安全,通过构建数理模型,分析了在以两个中间商为主体的农产品供应链中,中间商为实现自身利润最大化决定其实施的农产品价值增值水平和销售价格,上游产地市场决定供给中间商的农产品最优价格,以及需求量对农产品本身价格、价值增值水平、价值增值差异的敏感度,中间商经销农产品的相互替代程度、从事价值增值活动的成本对最优决策变量的影响。依据结论提出确保农产品的优质优价,加强政府在农产品流通环节的质量安全检测、追溯投入,基于不同地区农业发展情况,促进不同流通组织模式运行等建议。

This paper, in order to improve the value-added level of the agricultural products in the circulation link and ensure the quality and safety of the agricultural products, builds the mathematical models to analyze the value-added level of the agricultural products and the price for the middlemen to maximize their profits, the optimal price of the upstream market, and the influencing factors, inclu- ding the sensitivity of the demand for the agricultural price, the sensitivity of the demand for the value-added level, the sensitivity of the demand for the value-added difference, the degree of substitu- tion of the agricultural products, and the value-added cost. According to the results, some sugges- tions, such as assuring high price for high quality, strengthening the input of the government for the quality and safety testing and the traceability in the circulation of the agricultural products, promoting different running mode of the circulation organization on the basis of the agricultural development in different regions, are put forward.
