| This paper takes Shandong Province as an example to analyze the present situation of exploitation and utilization of coal resources in Shandong Province. The huge consumption of coal resources has supported the rapid development of Shandong Province. The annual contribution rate of coal economy to economic growth in Shandong Province is about 15% Shandong Province, the utilization of coal resources is not high, there is a big waste. In this paper, the data of Shandong Province from 2005 to 2015 are selected and the coal consumption efficiency of Shandong Province is measured and decomposed from provincial, industry and city levels by constructing the Super SBM (Undesirable Output) model of coal efficiency in Shandong Province. , Found that Shandong Province, the overall efficiency of coal is not high, the average annual efficiency of only 0.310 level, ranking ninth in the country; industry coal consumption efficiency in the heavy industry sector efficiency level is lower than the first and third industries,energy saving and emission reduction space The coal efficiency of the coastal cities of Qingdao, Weihai, Yantai and Dongying is higher, the coal efficiency of the inland cities is relatively low, and the space of energy saving and emission reduction is relatively large. . Secondly,through two-stage method, this paper analyzes the influence factors of coal efficiency in Shandong Province, and points out that economic development, technological progress and opening-up level have a good promotion effect on coal efficiency in Shandong Province, while industrial structure and energy consumption The structural imbalance has seriously hindered the improvement of coal efficiency in Shandong Province. The coal consumption efficiency of Shandong Province was clustered by different industries and regions, so as to better promote the development of coal economy in Shandong Province according to local conditions, and promote the clean and efficient use of coal resources. |
