摘要:

原油市场定价能力对高标准市场体系的建设以及要素市场运行机制的健全有着重要意义。为判断上海原油期货的推出对原油市场定价能力产生的影响,本文基于多尺度分析方法构建了时变信息份额模型,实证检验了2001年12月—2020年11月我国原油市场定价能力的动态演变过程。研究结果表明:(1)原油期货的价格在原油市场占主导地位,各市场定价的能力在样本期相对稳定,但也受到重大事件的影响;(2)上海原油期货在上市后获得了28.84%定价份额,已显现出一定的定价能力,但其在整体尺度以及高频和中频时间尺度上的定价能力均有较大提升空间;(3)在不同时间尺度下,原油市场定价能力的演变具有一定的异质性,在高频尺度上,上海原油期货推出后,获得31.54%的定价权,但并未弥补大庆现货市场定价能力下降的缺口;在中频尺度上,上海原油期货定价能力相对较低;而在低频尺度上,上海原油期货推出后,其定价份额占45.58%,对原油定价产生了显著影响。为提高上海原油期货的定价能力,市场运行机制的改善应着眼于高频与中频时间尺度上定价能力的提升。

Abstract:

Crude oil market pricing power is of great significance to the construction of a high-standard market system and the improvement of factor market operating mechanism. To judge the impact of Shanghai crude oil futures on the pricing power of the crude oil market, a time-varying information share model is constructed based on a multi-scale analysis method to empirically test the dynamic evolution of China’s crude oil market pricing power. The spot price of Daqing crude oil, prices of Brent crude oil futures, WTI crude oil futures, and Shanghai crude oil futures from December 2001 to November 2020 are adopted as the research sample. The research results show that: (1) the price of crude oil futures dominates crude oil market, and the pricing power of each market is relatively stable during the sample period, but it can be affected by extreme events; (2) Shanghai crude oil futures gain a 28.84% pricing share and has shown certain pricing power after its launch, however, its pricing power has much room for improvement on the whole and on high-frequency and medium-frequency time scales. (3) under different time scales, the evolution of crude oil market pricing power shows the characteristics of heterogeneity. On the high-frequency scale, Shanghai crude oil futures receive 31.54% of the pricing power after its introduction. Despite of this pricing power, it does not fill the gap which is caused by the decrease of the pricing power of Daqing spot market. On the medium-frequency scale, the pricing share of Shanghai crude oil futures is lower than pricing power of other frequency domains. On the low-frequency scale, after the introduction of Shanghai crude oil futures, with a pricing share of approximately 45.58%, INE has gained a dominant role. To improve the pricing power of Shanghai crude oil futures, the improvement of the market operation mechanism should be focused on the improvement of pricing power on the high frequency and medium frequency time scales.
