动力煤期货价格与现货价格动态关系研究

运用协整分析、向量误差修正模型、脉冲响应分析等多元时间序列计量经济方法,对2013年9月26日-2015年3月25日我国郑商所活跃合约的动力煤期货价格和秦皇岛港23.0 MJ/kg动力煤现货价格的动态关联性进行了研究。研究结果表明:动力煤期货上市至今,期货价格和现货价格具有长期协整关系,期货价格在均衡系统中起单向引导作用,误差修正项对现货价格的调整作用显著,对期货价格的调整效果不显著。期货市场的短期价格波动可以加剧现货价格的波动,反之现货市场的短期价格变化并不能显著影响期货价格。因此,期货价格虽然对现货价格起到一定的引导作用,但此种引导并不能有效反映现货市场的实际供需情况。这与我国动力煤期货市场发展尚不成熟、交易规则不够灵活、投机交易多而套期保值参与度不高等因素有关。

基于VAR模型的我国动力煤价格影响因素实证研究

动力煤是我国煤炭的主体,其价格波动不仅能准确反映煤炭价格变化,而且会冲击经济增长。本文运用VAR模型、协整等计量方法研究经济增长、内部供给、对外贸易依存及替代能源价格与动力煤价格间的动态关系。结果表明四因素与煤价间存在长期协整关系;经济增长、内部供给与国际油价是动力煤价格的强格兰杰原因。短期内,国际油价冲击大于经济增长及内部供给对煤价的影响,而对外贸易依存的冲击最小;长期看,经济增长对动力煤价格的冲击日益增加,国际油价与内部供给的冲击在迅速达到峰值后缓慢下降,对外贸易依存的冲击增长非常缓慢。因此抑制动力煤价格的剧烈波动一方面应该通过转变经济增长方式,淘汰落后产能,转变产业结构,另一方面应加大动力煤进口规模,减缓国内资源消耗速度,利用倒逼机制促进国内动力煤产业健康发展。
