Competitiveness Evaluation of Marine Engineering Equipment Manufacturing Enterprise Based on BP Neural Network: Evidence from A-Share Listed Companies

The marine engineering equipment manufacturing industry is characterized by high technology and high added value. It is one of the key industries for “Made in China 2025”, the foundation for China to build maritime and manufacturing power, and an important step to maintain the interests of national maritime security. The industry's safe and independent development depends on the central role of enterprises, and the improvement of the competitiveness of enterprises plays a considerable role in promoting the transition to new from old economic engines and the formation of the system of the whole industry. Combining with the characteristics of China's marine engineering equipment manufacturing enterprises, we establish the competitiveness evaluation system, determine the index weight using the Analytic Hierarchy Process, and set the BP neural network model for the competitiveness evaluation of China's marine engineering equipment enterprises. We analyze the sensitivity of the index through BP neural network, summarize the influencing factors of enterprise competitiveness, and combine them with the advantages of Japanese and Korean vital enterprises to provide a reference for the competitiveness of China's marine engineering equipment manufacturing enterprises. Results show that most of our country's marine engineering equipment manufacturing enterprises have significant differences between production and marketing ability, environmental support ability, and R&D ability. At the same time, the degree of influence of secondary indicators on competitiveness varies from company to company, so we have formulated the corresponding strategy to enhance the overall competitiveness and promote the healthy and sustainable development of the marine engineering equipment manufacturing industry.
