珠宝企业对黄金价格变动的灵敏性分析

如今金、工分离的黄金饰品销售方式使得黄金饰品的价格越来越透明。珠宝企业对黄金价格变动的灵敏度的高低不仅关系到消费者的权益，更关系到珠宝企业的利润。通过数学建模和运用MATLAB软件，分析了珠宝企业对黄金价格变动的灵敏程度。结果显示，灵敏性从高到低依次为：全国性知名珠宝企业（包括港资）、一般区域性珠宝企业和当地私营珠宝企业；灵敏性的差异源于不同珠宝企业受黄金市场、地方政策及经营模式影响程度的不同。研究发现，所调查的珠宝企业对金价均是追涨止跌，以获得最大利润。

The sensitivity of the gold price is related to both the consumers＇ rights and the profits of jewerly enterprises. Mathematical models and MATLAB software are used to analysize the retail price of gold jewelry in this paper. The results show that the sensitivities are as follows from high to low： the national well-known jewelry enterprises （including Hong Kong-owned）, the regional jewelry enterprises and the local private jewelry enterprises. The difference of the sensitivity is from the influence of the gold market, the local policies and the business model for the different enterprises.
