国际能源机构指出,目前现状是美国天然气供过于求,采购价格仅为欧洲的1/3、日本的1/5。因此分析称,如果目前的价格差异持续下去,大量消耗能源的化工、钢铁、铝业、造纸和石油冶炼等产业的差距将进一步扩大,这些出口产品在世界市场所占的份额将大幅改变。从行业专家对丙烯和丁二烯未来价格走向的判断来看,北美巨大的页岩气储备量和美国成熟的页岩气的开发水平,使得基础化工行业在丙烯的采购价格上无疑可以享受稳定、低价的原料供应。“ International Energy Agency pointed out that the current status of the US natural gas oversupply, the purchase price is only 1/3 in Europe, Japan, 1/5. Therefore, according to the analysis, if the current price differences continue, the gap between the energy consuming chemical, steel, aluminum, paper and oil refining industries will further widen, and the share of these export products in the world market will change drastically. From the judgment of industry experts on the future price trend of propylene and butadiene, the huge reserve of shale gas in North America and the development level of the mature shale gas in the United States make the basic chemical industry undoubtedly enjoy a stable purchase price of propylene , Low-cost supply of raw materials. ”
