中国煤炭产业集中度影响因素分析

An empirical analysis of market concentration in coal industry

在产业组织理论经典的SCP(结构-行为-绩效)分析范式中,市场结构通过影响市场行为,进而可以影响市场绩效。调整和改善不合理的市场结构是提高目标市场绩效的重要手段。产业集中度是重要的市场结构指标,它的变化的影响因素一直是产业经济学研究的重要内容。文章将产业组织理论和计量经济方法相结合,运用统计学相关方法及统计软件,对我国煤炭产业集中度的主要影响因素进行定量的实证分析,最终确立期初集中度、进入壁垒、市场容量、扩张能力等指标与煤炭产业集中度之间的数量关系,为制定我国煤炭产业又好又快发展的产业政策提供参考。

Based on the classical SCP（structure-conduct-performance） paradigm in industry organization theory,market structure has an effect on market performance by influencing market conduct.Adjusting market structure is an important way to improve market performance.Concentration is the first-line measure of market structure indicators,the level of industrial concentration and the determinants of changes in industrial economics has been an important aspect of the study.The paper links the theory of industry organization with the econometrics method,analyzes the factors affecting concentration in our coal industry with the aid of methods of statistics and the statistical software,and establishes the quantitative relations between concentration and the forepart concentration,barrier to entry,capacity of the market and the expansion power factors in the end,offers reference to set industrial policy for the sound and fast development of our coal industry.
