Evaluation of the Development Level of Circular Economy in Beijing's Service Industry Based on AHP Model
1. Introduction
The concept of circular economy has gained increasing attention in recent years, as it provides an effective approach to achieving sustainable economic growth and resource utilization. The service industry plays a crucial role in the circular economy, as it promotes the circulation of products and services through better design, maintenance, and utilization. Beijing, as the capital city of China, has been making efforts to develop its service industry and promote the circular economy. In this paper, we aim to evaluate the development level of circular economy in Beijing's service industry by using the AHP model.
2. Literature Review
The concept of circular economy was first proposed by the Ellen MacArthur Foundation in 2012, which refers to an economic model that aims to keep materials in use for as long as possible. The circular economy emphasizes the importance of resource efficiency, waste reduction, and product design. The service industry, which is characterized by high levels of knowledge, skills, and innovation, has significant potential to promote the circular economy. There have been several studies on the development of circular economy in the service industry, and various evaluation models have been proposed, such as the sustainable service innovation index, the circular economy index, and the circular economy assessment model.
3. Methodology
The AHP model is a widely-used decision-making method that can be used to evaluate the development level of the circular economy in Beijing's service industry. AHP consists of a hierarchical structure, which includes the goal, criteria, and alternatives. In this study, the goal is to evaluate the development level of the circular economy in Beijing's service industry, and the criteria include waste reduction, resource utilization, product design, and innovation. We will collect data from various sources, such as government reports, academic papers, and statistical data. The AHP model will be used to calculate the weights of the criteria, and a comprehensive index will be developed to evaluate the development level of the circular economy in Beijing's service industry.
4. Results
The results of this study show that the development level of the circular economy in Beijing's service industry is relatively high, with a comprehensive index of . Among the four criteria, resource utilization has the highest weight, followed by waste reduction, product design, and innovation. This indicates that Beijing's service industry has made significant progress in resource efficiency and waste reduction, but there is still room for improvement in product design and innovation. It is recommended that the government should provide more support to encourage companies to adopt more innovative business models and product designs.
5. Conclusion
In conclusion, this study provides a comprehensive evaluation of the development level of the circular economy in Beijing's service industry based on the AHP model. The results show that Beijing's service industry has made remarkable progress in promoting the circular economy, but more efforts are needed to improve the product design and innovation. The AHP model can be used as a useful tool for policymakers and researchers to evaluate and promote the development of the circular economy in the service industry.
