【摘要】：石油化工是我国重要的基础能源行业,它关系到我国的国计民生,与国家的安全、综合国力、人民的生活水平息息相关。从GDP总量来看,石油化工行业的增加值逐年上涨,我国已成为第二大经济体。然而,石油化工行业是一种高能耗、高污染的行业,在生产加工过程中各种能源的输入,又伴随着各种对环境的破坏,其中,化工行业的工业三废比例尤为突出,因此,准确的把握石油化工企业的生态效率特征,并运用正确的方法对生态效率进行评价,对解决企业的可持续发展具有重要的意义。本研究以大庆石油化工企业为例,对石油化工企业生态效率评价理论和方法做了深入探讨,首先通过文献研究、企业调查以及对国内外研究的比较,构建了与我国石化企业特点相适应的生态效率评价指标体系;其次,通过传统DEA与超效率DEA结合的方式对大庆石油化工企业进行生态效率与经营效率的比较分析,发现二者的差异性,为探讨生态效率影响因素做铺垫,并运用投入导向规模效益可变的BCC模型进行测算,利用DEAP2.1和Lingo软件计算评价结果,分析企业生态效率无效的原因,并给出具体的改进目标与方向,对生态效率有效的决策单元进行排序,明确企业的行业地位;再次,对大庆石油化工企业生态效率评价情况进行总结分析,为提高石油化工企业生态效率提出了应树立企业生态效率理念、强化企业控制管理、加强企业技术创新管理和加快企业的循环经济体系的建设入手;最后,综合分析研究后得出论文的结论。
[Abstract]:Petrochemical industry is an important basic energy industry in China, which is closely related to the national economy and people's livelihood, the national security, the comprehensive national strength and the living standard of the people. In terms of GDP, the added value of petrochemical industry has increased year by year, and China has become the second largest economy. However, petrochemical industry is a kind of high energy consumption and high pollution industry. In the process of production and processing, the input of various kinds of energy is accompanied by a variety of damage to the environment, among which, the proportion of the three industrial wastes in the chemical industry is particularly prominent. It is of great significance to grasp the characteristics of the ecological efficiency of petrochemical enterprises and evaluate the ecological efficiency by using the correct method to solve the sustainable development of the enterprises. Taking Daqing petrochemical enterprise as an example, this paper makes a deep discussion on the theory and method of ecological efficiency evaluation of petrochemical enterprise. Firstly, through literature research, enterprise investigation and comparison of domestic and foreign research, The ecological efficiency evaluation index system adapted to the characteristics of petrochemical enterprises in China is constructed. Secondly, the ecological efficiency and management efficiency of Daqing petrochemical enterprises are compared and analyzed through the combination of traditional DEA and super-efficiency DEA. The difference between the two is found. In order to explore the influencing factors of ecological efficiency, and to use the BCC model with variable input oriented scale benefit to calculate and evaluate the results, using DEAP2.1 and Lingo software, the paper analyzes the reasons why the enterprise's ecological efficiency is not effective. And give the specific improvement objectives and directions, the ecological efficiency of effective decision-making units to sort out the status of the industry; thirdly, Daqing petrochemical enterprises ecological efficiency evaluation situation is summarized and analyzed. In order to improve the ecological efficiency of petrochemical enterprises, it is proposed that the concept of enterprise ecological efficiency should be set up, the control management of enterprises should be strengthened, the management of technological innovation of enterprises should be strengthened and the construction of circular economy system of enterprises should be accelerated. After comprehensive analysis and research, the conclusion of the paper is drawn.
