The Ellison-Glaeser (EG) index and the CR5 index were used to give a dynamic calculation and analysis of the industrial agglomeration level of China in the article based on the data of five branches of China′s mineral resources industry, which conclued the coal industry, oil and gas industry, non-metal industry, ferrous metal industry and non-ferrous metal industry from 2000 to 2009. The results showed that during 2001 to 2009, the mineral resources industry on the whole had developed to a relatively high level but at a relatively slow speed. The EG index of the four branches of the mineral resources industry was calculated as above 0.05 in 2009 except for that of the non-metal mineral industry; the five branches′ CR5 index presented an apparent agglomeration, which held at a level of 0.6 in most conditions. The oil and gas industry had the highest average value of 0.657, and the lowest was the non-metal mineral industry, which was only 0.512. On the other hand, from an industrial perspective, the calculation results of the EG index revealed great differences in agglomeration level and uneven developments among the five mineral resources branches. The branch which was heading for the top position of the EG index was the ferrous metal industry with an average value of 0.102 , which was five times as that of the non-metal industry. The coal industry came in at second and the nonferrous metal industry and oil and gas industry were at No.3 and No.4. The last position was held by the non-metal industry with an average value of only 0.028, which was the only mineral resources industry that did not present a high agglomeration level. In addition, there were some differences in the variable range of agglomeration levels among the five mineral resources industries. In contrast, the oil and gas industry had the maximal increase slope of 85.17%, while the non-metal mineral industry′s development was comparatively slow, which had presented an evident decline since 2008. The slow or negative increase slope would make high agglomeration levels hard to sustain. However, the CR5 index showed that the difference among the five branches of the mineral resources industry was relatively small. All five industries presented relatively low or negative increase amplitude; the coal industry was the biggest among the industries at only 4.41%. The reason being that the non-metal mineral enterprises of the first five ones in turnover, enjoyed a geographical agglomeration resulting in the non-metal mineral industry showing a high agglomeration level. This narrowed the differences of agglomeration levels between this and the other branches.
