摘要
基于产业组织理论,对当前我国煤炭产业集中度进行了测算,并根据2004—2013年10年间的产业集中度变化趋势,认为我国虽然目前产业集中度偏低,仍处于低集中的竞争型市场结构,但已经积聚了向寡头主导型结构的势力。同时,还对产业集中度的影响因素进行分析研究,构建了我国煤炭产业集中度与期初集中率、进入壁垒、市场容量和生产扩张能力等因素的多元回归模型,并根据回归结果提出了产业政策的相关建议。
Based on a industrial organization theory, an estimation was conducted on the concentration of China coal industry.According to the variation tendency of the industrial concentration in the passed ten years from 2004 to 2013, the paper hold that although the present industrial concentration in China was low, but still was lower than the concentrated competed market structure and would have an accumulated power to an oligopoly leading type structure. The paper had an analysis and study on the factors affected to the industrial concentration. A multiple linear regression model was established on China coal industry concentration and initial concentration rate, in a barrier, market volume, production expansion capacity and other factors.Related proposals of the industrial policy were provided according to the regression results.
