摘　　要：学术界对煤炭产业的市场结构与市场绩效的关联度的研究主要集中在煤炭产业集中度与市场绩效的关系上,存在一定的局限性。文章首先以集中度和进入壁垒分析煤炭产业的市场结构,以利润率、安全绩效分析煤炭产业的市场绩效,然后将市场结构和市场绩效的指标引入灰色关联分析模型,运用灰色关联分析法对市场结构与市场绩效的关联度进行探索,得到煤炭产业市场集中度与利润率关联度大,而进入壁垒与安全绩效关联度大的结论。在此基础上提出提高煤炭产业集中度以进一步提高利润率,以及提高煤炭产业进入壁垒以进一步提高安全绩效的政策建议。There are some limitations in the studies of the correlation between the market structure and the market performance of the coal industry, which focus on relationship between the concentration and the market performance of coal industry. Beginning with the analysis of the market structure, the profit margin, the safety performance and the market performance of coal industry from the concentration and the entry into barriers, this paper introduces the indexes of market structure and market performance into Gray Correlation Analysis Model and makes a preliminary exploration about the market structure and performance with the Gray Correlation Analysis method. Finally, it comes to a conclusion that there is a high correlation between the coal industry market concentration degree and the profit margin, and a high correlation between the entry into barriers and the safety performance degree. Based on this con- clusion, the paper puts forward the policy suggestions as to improving the concentration of coal industry to promote profitability, and enhance the entry into barriers of coal industry in order to improve the safety performance.
