【摘要】：随着世界能源短缺和环境污染矛盾的日益加剧,如何提高能源利用效率成为世界所关注的话题,而实施循环经济和节能减排成为必要措施,我国也在大力推行循环经济和生态文明建设,提倡清洁、绿色、低碳生产,并致力于寻求一个缓解能源和环境矛盾的可持续发展道路。对于我国造纸行业来说,其特点是技术密集、工艺繁琐、流程复杂、能源消耗量大、污染严重,是我国发展循环经济和实施节能减排工作的重点监测行业;并且我国是纸产品生产和消费大国,随着市场需求不断扩大,进而也产生了大量中小型造纸生产企业,导致更大的能源需求量;与此同时,我国经济新常态下传统造纸企业亟需转型升级,其中能源利用效率是企业转型升级中要解决的突出问题。因此为提高造纸企业能源效率水平、减少环境污染,让造纸企业能够真正转型为资源节约型、环境友好型企业,本文在循环经济视角下对我国造纸企业能源效率评价指标体系进行了研究,对社会、政府、企业自身来说都具有十分重要的现实意义。首先,本文在通过文献研究法阅读了大量国内外相关文献后进行整理分析的基础上,从循环经济的研究视角切入,研究我国造纸企业能源利用现状以及影响我国造纸企业能源利用效率的因素,为下文指标的选取进行了铺垫。其次,构建一套循环经济视角下我国造纸企业能源效率评价指标体系,其中包括5个我国造纸企业能源效率的影响因素指标,即造纸企业规模、自产能源能力、技术装备水平、能源消费结构、能源管理水平指标,和3个循环经济相关指标,即能源循环经济效率、能源环境效率、资源循环利用效率指标,并在此基础上运用AHP层次分析法和熵权法的组合值来确定最终指标权重,结合灰色关联评价模型构建出循环经济视角下我国造纸企业能源效率评价指标体系。最后,根据我国造纸企业分布特点,在全国范围内选取了东部地区3家、中部地区2家、西部地区1家共6家具有典型代表的样本企业进行循环经济视角下我国造纸企业能源效率评价指标体系的实证研究,得出我国造纸企业能源效率利用情况整体水平一般,造纸企业能源利用有待进一步改善,在此结果基础上,分别从循环经济建设、能源消费结构、造纸企业规模、技术进步四个方面提出提升我国造纸企业能源效率水平的对策建议,为我国造纸企业及其他行业能源利用提供借鉴。
[Abstract]:With the increasing contradiction between energy shortage and environmental pollution in the world, how to improve the efficiency of energy use has become a topic of concern in the world, and the implementation of circular economy and energy saving and emission reduction has become a necessary measure. China is also vigorously promoting the construction of circular economy and ecological civilization, advocating clean, green and low-carbon production, and seeking a sustainable development path to alleviate the contradiction between energy and environment. For China's papermaking industry, it is characterized by intensive technology, cumbersome process, complex process, large energy consumption, serious pollution, which is the key monitoring industry to develop circular economy and implement energy saving and emission reduction in China. And China is a big country in paper products production and consumption. With the expansion of market demand, a large number of small and medium-sized papermaking enterprises have also been produced, resulting in greater energy demand; at the same time, Under the new normal state of Chinese economy, traditional papermaking enterprises are in urgent need of transformation and upgrading, among which energy efficiency is an outstanding problem to be solved in the process of enterprise transformation and upgrading. Therefore, in order to improve the energy efficiency level of papermaking enterprises and reduce environmental pollution, so that papermaking enterprises can truly transform into resource-saving and environment-friendly enterprises. In this paper, the evaluation index system of energy efficiency in Chinese papermaking enterprises is studied from the perspective of circular economy, which is of great practical significance to the society, government and enterprises themselves. First of all, on the basis of reading a large number of related documents at home and abroad through literature research, this paper analyzes from the perspective of circular economy. This paper studies the present situation of energy utilization in Chinese papermaking enterprises and the factors that affect the energy utilization efficiency of Chinese papermaking enterprises, which paves the way for the selection of the following indexes. Secondly, the paper constructs a set of evaluation index system of energy efficiency of Chinese papermaking enterprises from the perspective of circular economy, which includes five influencing factors of energy efficiency of Chinese papermaking enterprises, that is, the scale of papermaking enterprises, their own energy production capacity, and the level of technical equipment. Energy consumption structure, energy management level, and three related indicators of circular economy, that is, energy cycle economic efficiency, energy environment efficiency, resource recycling efficiency, On this basis, the combined value of AHP and entropy weight method is used to determine the final index weight, and the evaluation index system of energy efficiency of Chinese papermaking enterprises under the perspective of circular economy is constructed by combining the grey relational evaluation model. Finally, according to the distribution characteristics of Chinese paper-making enterprises, three eastern and two central regions are selected in the whole country. An empirical study on the evaluation index system of energy efficiency of Chinese papermaking enterprises from the perspective of circular economy is carried out by a sample of 6 typical enterprises in the western region, and the general level of energy efficiency utilization in China's papermaking enterprises is obtained. The energy utilization of papermaking enterprises needs to be further improved. On the basis of these results, the construction of circular economy, the structure of energy consumption, the scale of paper enterprises, Four aspects of technological progress are put forward to improve the energy efficiency of Chinese papermaking enterprises, which can be used as a reference for Chinese papermaking enterprises and other industries.
