矿业城市可持续发展效率评估与优化

Evaluation and optimization of sustainable development efficiency of mining city in the field ecological innovation

矿业城市在我国经济建设中占有重要地位。如何提升矿业城市的核心竞争力,促进其可持续发展,是时下亟待解决的重大课题。文章以此为视角,选取万元GDP能耗、人均固定资产投资、污染治理投资占GDP比重3个投入指标和矿业废弃物综合利用率、矿山破坏土地恢复率2个产出指标,形成矿业城市效率评价指标体系;从不同区域选取9座不同类型的矿业城市为研究对象,以3座"优秀矿业城市"为参照,借助DEA方法对其发展瓶颈和效率进行评估与优化。研究结果表明,通过深入挖掘矿业城市的资源潜力、构建多元发展战略、并通过技术创新强化生态环境保护工作等,可以完成矿业城市的能力重整,提升矿业城市的核心竞争力。

Mining city plays an important role in the construction of national economy.How to enhance the core competitiveness of mining city and promote its sustainable development is a major issue to be solved nowadays.With such a perspective,by selecting three input indicators of energy consumption of$10,000 GDP,fixed assets investment per capita,share of GDP in investment of pollution control;two output indicators of the rate of mining waste comprehensive utilization and the rate of the destruction of land mine recovery form a mining city efficiency evaluation index system.By studying nine different types of mining cities from different regions,and three outstanding mining cities as reference,the Data Envelopment Analysis（DEA）method is applied to evaluate and optimize the development bottleneck and efficiency.The results show that by digging mining resource potential of the mining city,building diversified development strategy,and strengthening ecological and environmental protection by the way of technological innovation,can complete the reform of mining city and enhance the core competitiveness of mining cities.
