The general aviation industry is an emerging industry in China and the key industry for the development of digital transformation. Using the rooted analysis method, this paper analyzes the digital transformation and development of 21 listed general aviation enterprises and summarizes four basic modes of digital transformation and development: digital production, digital research and development, product intelligence, and industry intelligence. The competitiveness evaluation model of the enterprise is constructed, and this paper makes an empirical and comparative study on the competitive promotion effect and main factors of the four digital practices of navigation enterprises. The results show that digital development has improved the competitiveness of enterprises to varying degrees. The competitive performance of general aviation enterprises developing in digital R&D model and composite model is stronger, while the competitive performance of general aviation enterprises with weak digital practice is the worst. Based on the analysis and summarization of the characteristics of each digital development model, effective ways to promote the competitiveness of the general aviation enterprises are proposed.
