中国煤炭产业买方市场势力实证研究

An Empirical Study of the Strength of Buyer's Market in China's Coal Industry

通过对中国煤炭产业的买方市场势力的量度,得到趋势向上的结论。目前买方市场势力与煤炭产业集中度高度正相关、与利润率显著正相关,与后者的关系与大多数实证结论相悖,究其原因是中国目前煤炭需求的特殊性和产业"边际"集中度增速较快。通过测算煤炭细分市场———炼焦煤市场的集中度,认为其市场结构特征是寡占型;追踪最新的钢铁行业市场结构变化特征,研究结论是钢铁产业集中度的提高推动了炼焦煤市场价格。国家产业政策应鼓励电力企业后向一体化,加快钢铁、水泥等产业兼并重组,促进产业均衡良性发展,确保国民经济稳定运行。

Through the measurement of the strength of the buyer＇s market in China＇s coal industry, an upward tendency can be drawn. At present, the strength of the buyer＇s market shows a positive correlation with the degree of concentration of the coal industry and a significant positive correlation with the interest rates, the later is contradictory to most empirical results. The reason for that is found to be the unique demand of coal at present China and the faster increase of ＂marginal＂ concentration of the industry. Through the It of the coal market segment--the concentration of the coking coal market, it is believed that the characteristics of the market structure belong to monopoly type; By tracing the latest changing characteristics of the market structure of the steel and iron industry, the conclusion of the study shows that the rising of the concentration in the steel and iron industry has driven up the market price in the coking coal market. The industrial policies of the state should encourage the backward integration of the electrical enterprises, speed up mergers and restructuring in steel, cement and other industries, and promote the balanced benign development of the industries, so as to guarantee the stable operation of the national economy.
