如今，我国经济在接下来较长时期内将保持中高速增长，供给侧结构领域的改革也得到大力推进，使我国民航业的发展处于关键节点。同时，疫情影响造成客流锐减，全球民航业损失惨重。虽然中国针对疫情采取了行之有效的防控措施，帮助中国民航在世界范围内首先从疫情的冲击中恢复过来，但身处危机中的我们需要重新审视民航业，育新机，速转型，着力发展机场非航空业务便是这场危机所带来的机遇所在。机场停车楼作为非航空业务的重要组成成分，在经营过程中应注重资源的合理配置，提高生产力，但其管理机制不够精细，经营模式有待完善，车主需求未能满足，机场不给予认可，这些问题正让机场停车楼管理者伤透了脑筋。与停车楼顾客建立长期、稳定的关系，是机场停车楼的长远发展目标，想确定这一目标实现的可能性，同时明确服务改进方向从而实现服务质量的改善，当务之急是衡量顾客对于机场停车楼服务质量的满意程度。

    Nowadays,China's economy has shown a new state, which has promoted the transformation of the development mode and achieved the leap of the "middle-income trap". Moreover, my country's economy will maintain a medium-to-high speed growth for a long period of time in the future. Supply The reform in the field of side structure has also been vigorously promoted, making the development of my country's civil aviation industry at a critical point. At the same time, the impact of the epidemic has caused a sharp drop in passenger flow, and the global civil aviation industry has suffered heavy losses. Although China has taken effective prevention and control measures against the epidemic and helped Chinese civil aviation recover from the impact of the epidemic first in the world, we need to re-examine the civil aviation industry in the midst of a crisis, cultivate new opportunities, and make rapid transformation. Focusing on the development of non-aeronautical business at airports is where the opportunity lies in this crisis. As an important component of non-aviation business, the airport parking building should pay attention to the rational allocation of resources and improve productivity in the operation process.
However, its management mechanism is not refined enough, its business model needs to be  improved, the needs of car owners cannot be met, and the airport does not give approval. The problem is giving the airport parking lot manager a nerve-wracking one. It is the long-term development goal of the airport parking building to establish a long-term and stable relationship with the customers of the parking building. To determine the possibility of achieving this goal, and at the same time clarify the direction of service improvement to achieve the improvement of service quality, it is imperative to measure the customer's perception of the airport parking building. Satisfaction with service quality.

    This paper focuses on the parking lot of Daxing Airport, conducts a survey on the customers of the airport parking lot, intercepts car owners to fill in the questionnaire, conducts empirical research on the questionnaire data, analyzes the effect of user characteristics on customer satisfaction, and finds out that gender, age, identity, place of residence, travel Objective The impact of these user characteristics on customer satisfaction is not significant. In the relatively mature satisfaction model at this stage, the analytic hierarchy process is selected, combined with the actual characteristics of the parking lot of Daxing Airport, the subjective analysis and the objective analysis are combined, and the entropy value method, principal component analysis method, BP neural network and other methods are used. The strategy method is used to weight the indicators. After comparison, the optimal BP neural network method is selected to weight the indicators, and the customer satisfaction evaluation index system of the parking building of Daxing Airport is constructed.
