Developing China's high-tech industry is important to make the country innovation-oriented. This requires optimising the allocation of innovation resources and improving innovation efficiency. However, few studies have investigated this topic and the realisation path for the high-tech industry. This study develops an input-oriented inverse data envelopment analysis (DEA) model with frontier changes to analyse the optimisation of resource allocation in China's high-tech industry during 2019–2025. With this method, decision makers can scientifically analyse the specific amount of resource investment. We also construct an analysis framework from short- and long-term perspectives. The results show that the excessive input of research and development (R&D) personnel and unbalanced allocation of capital resources are the main barriers to the development of high-tech industries in the short term, and in the mid- and long terms, the demands for investment in talent and capital will continue to increase. Improvement directions for promoting the development of China's high-tech industry are discussed. Finally, we present valuable information for policymaking to promote progress in high-tech industries in different regions. [ABSTRACT FROM AUTHOR]

The development status of China's marine industry in recent years was qualitatively analyzed, and it is found that the scale of China's marine economy continued to expand, and the industrial structure has been continuously optimized. Then, the coupling and coordination degree between the development of marine industry and the gathering of marine talents were analyzed quantitatively, and it is found that the development of marine industry generally promoted the gathering of marine talents, but the promotion of each industry was weak. The influence of the development of marine industry on the gathering of marine talents should be strengthened. It is proposed that the development of marine industry should be promoted from the aspects of strengthening the planning level of industrial development, improving the efficiency of resource allocation, promoting the innovation and development of marine industry, and strengthening the management of marine talents, so as to enhance the influence of marine industry on the gathering of marine talents and form a benign interaction between talents and industry.
