花卉拍卖中两种品牌形式序贯拍卖价格的比较

Comparison of Price Trends for Two Brand Modes at Flower Auction

昆明国际花卉品牌市场的供货商存在两种主要的品牌形式:"通海"模式和"昆阳"模式."通海"模式下所有农户以一个统一的供应商向拍卖市场供货;而"昆阳"模式下尽管各农户品牌名称相同,但以独立的供货商向拍卖市场供货.论文基于该企业的实际数据,研究了两种品牌形式下序贯拍卖的价格趋势和波动趋势,通过一元线性回归,显示出"通海"模式下序贯拍卖价格趋势相对平稳且价格波动相对较小,研究结果表明"通海"模式下各批次质量差异较小.

The “Tonghai”mode and the “Kunyang”mode are two main brand modes at Kunming International Flower Auction Market （KIFA）.In the “Tonghai”mode,all the farmers with the same brand supply their flowers to KIFA as an identical supplier;whereas in the “Kunyang”mode,all the farmers with the same brand supply their flowers to KIFA as independent suppliers.Based on the actual data from KIFA,the paper simulates the price trend and fluctuation trend in the sequential auction for these two brand modes by using a linear regression.The simulation results show that the price trend and the fluctuation trend in the “Tonghai”mode is smoother than that of the “Kunyang”mode.It is concluded that the quality among different LOTs in the“Tonghai”mode is steadier than that of the “Kunyang”mode.
