Abstract The rapid development of the economy and the change in transaction mode has promoted the development of logistics parks. How to evaluate and optimize the ecological efficiency of logistics park to achieve its sustainable development has been considered a challenge. Therefore, this paper puts forward an emergy based ecological efficiency evaluation and optimization method for Logistics Park. By constructing the ecological efficiency evaluation model of logistics park, it quantitatively evaluates the ecological efficiency and sustainable development of logistics park, and analyzes the correlation between various factors and ecological efficiency. The application results of H Logistics Park show that fuel oil, information technology, net profit, and waste gas are closely related to the ecological efficiency of logistics park, and the correlation coefficients are 0.8248, − 0.6949, 0.8544 and 0.7661 respectively. On this basis, the paper puts forward some suggestions to improve the ecological efficiency of the logistics park. This paper provides theoretical and methodological support for the evaluation and optimization of the ecological efficiency of the logistics park.
