Abstract:In the first decade of the 21st century, as a typical coal province and mining economic region, Shanxi province made a great contribution to the national economic construction and reform. At the same time, coal mining has caused serious damage to the ecological environment, excessive use of resources, the deterioration of the ecological environment and a decline in the sustainable development capacity. Overreliance on a resource-based economy leads to problems such as a poorly developed economy and a single industrial structure. In this context, Shanxi province has to take actions to transform its industrial structure into a low-carbon development model as soon as possible. This paper measures the values of the consumption coefficients of capital investments, electric power and CO2 emissions by establishing a Grey Model
The supply of rare earths in China has been the focus of significant attention in recent years. Due to changes in regulatory policies and the development of strategic emerging industries, it is critical to investigate the scenario of rare earth supplies in 2025. To address this question, this paper constructed a dynamic computable equilibrium (DCGE) model to forecast the production, domestic supply, and export of China's rare earths in 2025. Based on our analysis, production will increase by 10.8%-12.6% and achieve 116,335-118,260 tons of rare-earth oxide (REO) in 2025, based on recent extraction control during 2011-2016. Moreover, domestic supply and export will be 75,081-76,800 tons REO and 38,797-39,400 tons REO, respectively. The technological improvements on substitution and recycling will significantly decrease the supply and mining activities of rare earths. From a policy perspective, we found that the elimination of export regulations, including export quotas and export taxes, does have a negative impact on China's future domestic supply of rare earths. The policy conflicts between the increase in investment in strategic emerging industries, and the increase in resource and environmental taxes on rare earths will also affect China's rare earths supply in the future.
The economy relies heavily on resources in China, which is particularly evident in resource-based cities where the resources industry takes up a high proportion in economic structure. The local mining industry affects or determines all social and economic aspects of the area. Whether the mining industry can achieve sustainability decides the future development of the region. This paper analyzes the fundamental implications of sustainability of mining industry from two logic perspectives, i.e. the economic and social development stages and microcosmic enterprises. We review the evaluation system of sustainable development of mining industry and establish an evaluation indicator system which covers four sub-objectives and 21 indicators. On the basis of feasibility principles, the lateral and vertical evaluations on the sustainability are performed on 8 resource-based cities including Jiaozuo. Being consistent with the actual situations, the conclusion has reference value for making policies.
