Space heating using straw briquette fuel in China rural is an important method to replace fossil fuels and reduce greenhouse gas emissions. However, the price of straw briquette fuel is high in traditional supply chain. Therefore, a novel closed-loop supply chain centered on energy service station is proposed. An appropriate way to acquire fixed assets can promote the rapid development of energy service station. In order to find a better solution, the methods of net present value and entropy weight are adopted. The results show that the priority order for small-scale energy service station is operating lease (OL), purchasing with loans (PL), purchasing with own fund (PF) and financial lease (FL), while that for large-scale energy service station is PL, OL, PF, FL. The results indicate that for small-scale energy service station, the optimal way to acquire fixed assets is affected by loan interest rate, rent interest rate and discount rate, while for large-scale energy service station, the optimal way to acquire fixed assets is mainly affected by loan interest rate, and the discount rate and rent interest rate have a negligible influence on the decision.
