大家伙儿老爱吐槽国内油价，说它涨得快跌得慢，简直像个笑话。国际油价一掉，它就装没看见，涨价时候倒追得紧。 可仔细想想，这事儿真没那么简单。很多人没搞懂国内油价到底锚定啥，以为就是随心所欲。实际上，这套机制有来头，牵扯国际市场、国家调控和民生平 衡。 油价这事儿，很多人觉得国内油价不跟国际同步，涨多跌少。其实，国内成品油价格形成机制从2009年就开始逐步完善，核心就是锚定国际原油价格。 不是随便定的，而是挂靠三种国际原油基准：北海布伦特原油、阿联酋迪拜原油和印尼米纳斯原油。这三种油价的平均变化，直接决定国内汽柴油零售价的 调整。 为什么选这三种？因为中国进口原油来源多样，布伦特代表欧洲市场，迪拜是中东的，米纳斯偏亚洲，能覆盖全球主要供需。 国家发改委每天监测这些油价的移动平均值，每10个工作日作为一个调价周期。周期内，如果国际原油均价变化导致国内成品油价变动超过每吨50元，就调 整；不到50元，就累加到下个周期，不动。 调价生效在发布日24时，汽柴油分开算，标准品为基础。2013年3月，这套机制进一步完善，把原先22个工作日的周期缩短到10个，取消了4%的幅度限制， 让调整更灵敏。 那时候正好徐绍史刚上任发改委 ...
