摘要: Traditional mineral resource availability assessment methods always have strong assumptions and limitations on application. Both the physical mechanism of the Hubbert model and the economic mechanism of the Hotelling model can evaluate only specific dimensions of the availability of mineral resources. Therefore, we propose a hybrid model that could explain mineral resource availability from geological factors to the metal market. In this model, mineral resource availability will be assessed by t关键词: Mineral resource availability;Mining technology;Geological constraint;Price elasticity

摘要: The urban agglomeration in the middle reaches of the Yangtze River, which is the second largest urban agglomeration in China, represents a typical land space range of ecological vulnerability in China. Large differences occur in economic development mode between resource- and non-resource-based cities in this basin area. Accurate identification of the evolution and regional differences in the production-living-ecological space (PLES) is very important in order to elucidate the development and ut关键词: production-living-ecological space;Theil index;ESDA;regional differences

摘要: Improving the green total factor productivity (GTFP) of the extractive industries is an important way to promote high-quality and green development of the extractive industries in China. Due to technological heterogeneity, the GTFP in China's extractive industries may be biased and cause efficiency losses. Therefore, we calculated the GTFP from 2006 to 2017 based on metafrontier and data envelopment analysis method, and analyzed the influencing factors. The results show that the contribution of 关键词: Green total factor productivity;Technology heterogeneity;Extractive industries;China

摘要: The transition of the economic growth in China from high-speed to high-quality development provides new challenges to strategic minerals (SMs) security. Under the transition, combined with its development status, but also to maintain global coexistence from the entire industrial chain, we in this paper first expound the security connotation of SMs and take lithium resources as an example to evaluate its security in China. Monte Carlo Simulation (MCS) is used for sensitivity analysis. Results sho关键词: Strategic minerals;Lithium security;Evaluation index system;Monte Carlo simulation (MCS)
