曲线回归在炼化产品价格分析中的应用

Curve Regression Applied in the Price Analysis of Refined Products

借助相关性分析和曲线回归等统计分析方法研究价格模型,建立了国际布伦特原油价格和国内炼化企业产品价格的函数关系式。通过函数的求导,还分析了产品价格相对原油价格的波动弹性。研究结果对于炼化产品价格预测和炼厂产品结构优化具有重要作用。

In this paper, we explored the product price research model with statistical analysis method, and established the function relation between the price of Brent crude oil prices and product prices in domestic refinery. Through the formula derivation, we also analyzed volatile elasticity of the product prices to crude oil price. The results of the study plays an important role in refining product price prediction and refinery product structure optimization.
