[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.
