Abstract:SRDI Firms are the driving force and leader in innovative development, as well as an important force in stimulating market vitality and promoting high-quality economic development. The internationalization development of SRDI firms is conducive to utilizing more technologies and funds for innovation, and obtaining a larger market, thereby achieving sustained improvement in competitiveness. The current development status of SRDI firms in China are reviewed. These enterprises have achieved significant results in terms of scale, technological innovation, and financing. However, there is still a certain gap from the internationalization level, and there are still problems such as low innovation level, slow digital transformation, low brand influence, lack of funds, small market scale, and lack of international competitiveness. The important measures taken by representative cities in China to promote SRDI firms to enhance their competitiveness and international development are summarized. Learning from their advanced experiences, the policy recommendations for the innovation and opening of four major elements: open innovation, data opening, market opening and financial opening are provided.
