基于DEA的内蒙古煤炭企业投资效率实证研究

煤炭产业是内蒙古自治区的支柱产业,煤炭企业的发展对内蒙古经济具有十分重要的意义。通过分析发现,当前内蒙古煤炭企业面临着新的发展形势:一是供需矛盾突出,产能过剩压力巨大;二是传统经济发展模式难以为继,急需进行产业升级;三是煤炭企业生产成本持续上升,盈利能力降低。面对新的发展形势,本文以数据包络分析(DEA)为基础,对内蒙古煤炭企业投资效率进行深入分析,探究其自身不足,通过与行业领先企业进行对比,提出煤炭生产企业发展战略。本文认为当前内蒙古煤炭生产企业投资效率整体较好,规模效率占据优势,但技术效率不足,经营业务较为单一;未来内蒙古煤炭生产企业应该努力提升管理水平和生产技术水平,扩大投资范围,实施多元化发展战略。

Empirical study of investment efficiency for coal enterprises of Inner Mongolia based on data envelopment analysis

Coal industry is a pillar industry in Inner Mongolia Autonomous Region, the development of coal enterprises has very important significance to the economy of Inner Mongolia. The analysis shows that the coal enterprises in Inner Mongolia are facing some new development situations: firstly, the contradiction between supply and demand is prominent, and the pressure of excess capacity is enormous; secondly, the traditional economic development model is unsustainable, and industrial upgrading is urgently needed; thirdly, the production cost of coal enterprises continues to rise, and the profitability is reduced. Faced with the new development situation, based on data envelopment analysis(DEA), this paper makes an in-depth analysis of the investment efficiency of coal enterprises in Inner Mongolia, explores their own shortcomings, and puts forward the development strategy of coal production enterprises by comparing with leading enterprises in the industry. The paper thinks that the investment efficiency of Inner Mongolia coal production enterprises is relatively good, scale efficiency dominates, but technical efficiency is insufficient and business operations are relatively single. In the future, Inner Mongolia coal production enterprises should strive to improve management and production technology, expand the scope of investment, and implement diversified development strategy.
