Abstract：Industrial parks are the basic units and main battlefields for energy conservation,pollution reduction,and carbon emission reduction.The construction of integrated energy systems in industrial parks is not only an important practical form of building a new energy system,especially a new power system,but also a strategic support for the development of new quality productive forces and the promotion of high-quality economic and social development.Using emergy analysis and DEA-SBM,this paper takes industrial parks as case studies to systematically evaluate the emergy and efficiency of integrated energy systems under different capacity configuration combinations.The rationality of this method is verified through calculations with specific park data.The results show that under the premise of constant load,different energy capacity combinations and multi-energy complementarity have a significant impact on the operation of the park.When the capacity configuration of the integrated energy system is set differently,the park integrated energy system with photovoltaic as the main component has the best efficiency evaluation.Sensitivity analysis of the system by changing typical days verifies the scientific nature of the research results.
