Evaluation of the Cyclic Economy Development Based on the Rough Sets and Extension Analysis

Abstract

Because of the subjectivity of the current index system of the cyclic economy and the lack of the comprehensive assessment of the trend for the economic development, the present paper proposes a rough-set-based approach to establish the index system for the cyclic economy and sets up the evaluation model for the cyclic economy development with the comprehensive extension evaluation method. The paper begins with the formalizing description and discretization of the initial economy index, establishing the assessment system with the Attribute Reduction method. Then the paper establishes a meta-model for the cyclic economy development and proposes the comprehensive extension evaluation method to assess the cyclic economy development based on the correlation function method. The index system based on the established assessment model is simple but comprehensive enough to assess the current development as well as analyse the trend of the future development of the cyclic economy, which can offer theoretical basis and working approach to development the regional cyclic economy. Finally, taking Gansu as an example, by making an empirical study on the related data in 2013, the paper establishes the index system for the cyclic economy in Gansu, and assesses the development and the trend of the cyclic economy in some areas of the province.
