作为我国国民经济的支柱型产业,煤炭贸易一直倍受关注,从2000年至2009年之间,煤炭产品的价格总是处在一种不断变化的状态之下。为了研究其中的利弊关系,找到能够影响其产生波动的原因所在,笔者花费大量的精力收集了这段时间内有关于煤炭贸易变化的各种进出口数据,力求从财务管理的角度找到问题的突破口。在经过详细的分析后得出以下初步结论:虽然煤炭贸易与产品价值之间存在着某种程度上的平衡关系,同时煤炭产品价格在拉动煤炭贸易进出口额上面表现出极强的能力,反之则不然;煤炭产品价格的冲击只能对煤炭贸易产生约为5年的效应期,不具备永久性;煤炭贸易中进出口额只表现出短期的正相关性,而不存在长期作用的关系。
As the pillar industry in our national economy, the coal trade has drawn great attention. From 2000 to 2009, the prices of coal products are always in a constantly changing state. In order to study the pros and cons of the relationship and find out the reasons that can affect its fluctuations, the author spent a lot of energy collecting all kinds of import and export data on the changes of the coal trade during this time, trying to find a breakthrough point from the perspective of financial management . After a detailed analysis of the following preliminary conclusions: Although there is a certain degree of balance between the coal trade and product value, while the price of coal products in the coal trade in the import and export volume above showed a strong ability, and vice versa Otherwise, the impact of coal product price can only produce effect period of about 5 years on coal trade, which is not permanent. The import and export volume of coal trade shows only a short-term positive correlation without any long-term effect.
