摘要
基于协整关系和格兰杰因果检验,对煤炭行业集中度与经济增长的影响进行了实证研究。研究结论表明:煤炭行业集中度和经济增长存在着长期均衡关系,并且双方存在着互为因果关系,进而为提高煤炭行业集中度提供了实证依据。
Based on the co-integration relationship and the granger cause test, the paper had an empirical study on the concen- tration ratio of the coal industry affected to the economic growth. The study results showed that there was long term balanced relationship between the coal industry concentration ratio and the economic growth, there was a mutual cause relationship be- tween the concentration and the growth and thus the empirical basis could be provided to improve the concentration ratio of the coal industry.
