A Simulation Study of General Aviation Cargo Policy in China: A System Dynamics Perspective

Currently, addressing the imbalances in the development of domestic general air freight and public aviation freight formats, as well as the imperfections in policies, regulations, and sys-tems, is crucial. This study employs system dynamics theory as its research method to con-struct a dynamic model of China's general aviation freight system. By examining the supply side, demand side, and the general aviation freight industry chain, the study illustrates the feedback relationships within general aviation freight and establishes an indicator system. Using Ven sim PLE software, the research creates causal relationship diagrams of the main subsystems and an overall system flow diagram. The model is quantitatively specified through historical and sensitivity testing. The findings indicate that varying levels of financial in-vestment and tax preferential policies significantly enhance the economic benefits of navigation and freight in China. Additionally, increased investment in scientific research funding is expected to advance the technical level of navigation operations. Therefore, it is recommended to boost investment in general air freight, implement preferential tax policies for air-craft manufacturing enterprises, navigation operating enterprises, and infrastructure support units, increase investment in R&D for the general cargo transport industry, and focus on the training and incentivization of navigation professionals.
