2013年3月国家发改委发布了新的成品油价格形成机制完善调整办法,新机制政策指向性明显,即在缩短调价周期的同时降低定价办法执行过程中的人为影响和随意性,保证机制和规则自身效用的最大化发挥。为考察成品油定价机制完善前后政策执行上的变化和差异,从实证角度出发,针对成品油定价机制调整以后在价格响应滞后性、规则透明度以及政策执行严谨性三个方面进行分析。分析结果表明,成品油定价机制调整后,国内成品油价格调整对于国际原油价格变化响应的滞后性明显缩短,定价政策执行的严谨性得到加强,价格调整触发和调价幅度计算的规则透明性有所下降。
In March 2013, the NDRC released a new adjustment and adjustment method for the price formation mechanism of refined oil products. The policy of the new mechanism is obviously directional. In shortening the period of price adjustment, the NDRC will reduce the artificial influence and arbitrariness in the implementation of pricing methods, and ensure the mechanism and rules Maximize the effectiveness of their own play. In order to investigate the changes and differences in policy implementation before and after the refined oil pricing mechanism is improved, the paper analyzes the pricing response lag, the rule transparency and the strict implementation of the policy for the refined oil pricing mechanism adjustment from the empirical point of view. The analysis shows that after the pricing mechanism of refined oil products is adjusted, the lag of domestic refined oil price response to the change of international crude oil price is obviously shortened, the rigor of pricing policy implementation is strengthened, and the rules transparency of price adjustment trigger and price adjustment range decline.
