Coordination Degree Evaluation of Energy-Economy-Environment System Based on P-S-R Model

摘要

The energy, economy, and environment systems are interacted, and the whole of the three systems is called the energy-economy-environment (3E) system. Energy is limited, and the expectations of human economic and social development are infinite while the two constitute a contradiction. At the same time, the irrational use of energy system will also trigger a series of environmental problems which will restrict economic and energy system development. Therefore, the pressure-state-response (P-S-R) model can better reflect the interaction between energy system, economy system and environment system. Based on this, the TOPSIS (technique for order preference by similarity to ideal solution) method is used to comprehensively evaluate the coordination degree of 3E system.
