选取2006年1月~2016年12月月度数据,构建协整检验模型。实证分析结果表明,定价机制改变对中国进口澳大利亚铁矿石的数量具有显著影响,会导致进口数量波动性显著增加;中国钢铁产量对其进口澳大利亚铁矿石的数量具有显著正向影响;澳大利亚铁矿石相对价格、海运费及其工人罢工损失工作日等对中国进口澳大利亚铁矿石的数量具有反向显著影响。据此,提出了加快化解钢铁产业过剩产能、提升海运市场主体地位、拓展多元化进口渠道、加大废钢有效利用、努力打造有利定价模式等对策建议。
Based on monthly data from January 2006 to December 2016, the results from co-integration test model show that the change in pricing mechanism significandy affected the iron ore trade quantity from Australia to China and led to obvious increasing in the variance of that quantity. China's steel production had a significant positive impact on the iron ore trade quantity; Australian iron ore relative prices, sea freight and lost working days caused by strikes in Australia, had significant negative impact on that quantity. We propose to resolve the overcapacity in the steel industry, enhance China's maritime market power, diversify the import channels, increase the effective utilization of scrap steel, and strive to build favorable pricing model.
