摘要
为研究区域经济增长与煤炭价格关系,以陕西省为例,首先初步研究了陕西经济增长与煤炭价格的相关性,然后对两者进行了协整检验以及格兰杰因果关系分析,确立了两者具有长期协整关系,并在此基础上建立了误差修正模型,进一步确立了陕西经济增长与煤炭价格的短期动态关系。最后,根据实证研究结果,提出了优化陕西煤炭产业价格与经济增长关系的政策建议。
In order to study a relationship between the regional economic growth and coal prices, based on Shaanxi Province as a case, the paper firstly had a preliminary study on a correlation between Shaanxi economic growth and coal prices and then had a co-integration test on the economic growth and coal prices. A long term co- integration relationship of the both was determined. Then based on the circumstances, an error correction model was established and a short term dynamic relationship between Shaanxi economic growth and coal prices was further determined. Finally according to the study results, a policy proposal to optimize a relationship between Shaanxi coal industrial price and economic growth was provided.
