Research on the Regional Development Index of China's Low-altitude Economy Based on the Entropy Weight Method

At present, the low-altitude economy, as a strategic emerging industry, serves as a pivotal driver of economic growth, technological innovation, and social service enhancement. In order to better assess the development of the low-altitude economy in different regions of China, this paper proposes a low-altitude economic development index based on the entropy weight method. First, following the principles of scientificity, systematicness and practicality, a 3X3 pyramid-shaped evaluation system is constructed; Then, the data will be preprocessed using the box plot method and the supplementary method; Finally, the entropy weight method was used to calculate the results of the low-altitude economic development index for different regions. The results showed that provinces in the eastern coastal region scored high, while those in the central and western regions lagged behind. The method can provide more targeted advice for policy-making and industrial development.
