Abstract: Based on the neo-classical production function,this paper analyzes the relationship between the economic growth and the concentration degree of the coal industry by using the co-integration relationship test, Granger causality and variance decomposition method. The conclusion of the study shows that there is a positive correlation and the long-term equilibrium relationship between the economic growth and the concentration of the coal industry. During the short period,there is a one-way Granger causality between the coal market concentration and economic growth. During the long term,there is the one-way Granger causality from economic growth to the coal concentration,from the capital stock to the coal concentration,from the human capital to the coal concentration, from the human capital to economic growth and from the economic growth to the capital stock. The impact of the coal market concentration,human capital as well as capital stock on the economic growth is not only fast and relatively strong. The coal concentration and human capital has a persistent impact on the economic growth,but the capital stock has not persistent impact on economic growth. This paper provides empirical evidence for increasing the concentration of the coal industry.
