With the rapid development of the digital economy and the rise of the industrial Internet, China has made significant progress in terms of industrial competitiveness and industrial innovation and development. However, China's capacity for independent technology innovation must be improved. Firstly, China's independent innovation capacity in key core technology areas could be more robust. This mainly manifests in China's reliance on imported technologies and equipment in high-end manufacturing and emerging industries. Although China has made certain technological breakthroughs in specific fields, there is a particular gap between China and the international advanced level. Secondly, the investment in technological research and development of Chinese enterprises must be increased. Although the R&D investment of Chinese enterprises is gradually growing as more attention is paid to scientific and technological innovation, there still needs to be a significant gap compared with developed countries. In particular, the R&D investment of small and medium-sized enterprises is relatively low, resulting in the overall level of independent technological innovation not being high. Again, China needs to strengthen the protection of intellectual property rights. For a long time, the construction of China's intellectual property protection system has been lagging, and the problem of intellectual property infringement is relatively prominent, which has formed a particular obstacle to independent technological innovation. Therefore, studying economic digital development restrictions and development strategies has profound theoretical and practical significance in the new development pattern.
