Of Guangxi has developed rapidly. Guangxi is rich in mineral resources, with a wide variety of types and large reserves, especially non-ferrous metals such as aluminum and tin. It is one of the ten key non-ferrous metal production areas in China. There are currently 145 kinds of minerals such as manganese, aluminum, tin, iron, arsenic, bentonite, vanadium, tungsten, indium, lead, zinc, and antimony silver that have been discovered in the territory, and 97 kinds of mineral reserves have been proven. According to The Overall Planning of Mineral Resources in Guangxi (2016–2020), the output value of mining and related energy and raw material processing and manufacturing industries was 673.8 billion yuan, accounting for 31% of the region’s total industrial output value. There are obvious regional differences in the distribution of mineral resources, mainly in Hechi, Baise, Chongzuo, etc. Most (82%) of manganese reserves are concentrated in Chongzuo and Baise, 96% of aluminum reserves are concentrated in Baise, 67% of tin reserves are concentrated in Hechi, and over 85% of rare earth reserves are concentrated in Yulin, Hezhou, and Guigang; 79% of the barite resource reserves are concentrated in Liuzhou and Laibin, 88% of the kaolin resource reserves are concentrated in Beihai, and 88% of the coal resource reserves are concentrated in Baise and Laibin. Part of the mineral reserves in Guangxi are even at the forefront of the world, so Guangxi is also known as the “hometown of non-ferrous metals.” [40] Thus, it is essential to study the sustainability of mining, the results of which may accelerate the construction of a major mining province and provide policy recommendations for promoting the sustainable economic and social development [41]. 2.2. Definition of the Composite Mining Eco-EfficiencyEco-efficiency refers to creating more goods and services while having less impact on the environment and less consumption of natural resources. It involves all aspects of the economy and society and is a complex and multi-dimensional problem [13]. This study constructs a three-dimensional analysis framework to reveal the relationship between ecological efficiency, environmental efficiency, resource efficiency, and economic efficiency. These four types of efficiencies are all based on total factor productivity. In order to maximize it, economic growth, resource assumptions, and environmental pollutants cannot be fixed, indicating that non-orientation should be more appropriate when measured eco-efficiency [30]. The meaning of eco-efficiency in this research: maximization of economic output, minimization of environmental pollution, and minimization of energy consumption.Economic efficiency
