Research on the optimization of investment structure of China's high-tech industries under the new development model of dual circulation

On May 14, 2021, at the Standing Committee of the Political Bureau of the CPC Central Committee, General Secretary Xi Jinping first proposed the concept of "dual circulation", emphasizing the construction of a new development pattern in which domestic and international dual circulations promote each other. Capital circulation is the primary link in opening up the circulation, and high-tech industries are the key areas in this new development pattern. In this context, it is of great significance and value to study the optimization of the investment structure of high-tech industries. This study takes the new dual circulation model as the starting point and conducts an in-depth analysis of high-tech industries from the perspective of investment structure optimization. By applying theories such as capital circulation, dynamic comparative advantage, and investment portfolio, the relationship between China's current economic development status and dual circulation is explained. At the same time, the development status of China's high-tech industries is compared with that of foreign high-tech industries, and the advantages, gaps, and problems between China's high-tech industries and developed countries are analyzed. The research plan explores the rationality of the investment structure of high-tech industries in the internal circulation, external circulation, and dual circulation from multiple perspectives such as industrial growth, investment efficiency, industrial upgrading, and global value chain. This will provide a theoretical basis and practical guidance for optimizing the investment structure of high-tech industries and help China achieve high-quality development under the new development pattern.
