Abstract: In recent years, the international promotion of technical standards based on the two factors of technology and market is two important paths for enterprises to realize the "going out" of technical standards. Based on this, this paper takes 76 communication companies with high activity in global technical standard internationalization as analysis samples, and uses negative binomial regression model to explore the promotion mechanism of technical standard internationalization from two aspects of market and technology. The main conclusions are as follows: (1) The two important factors of technology promotion and market promotion both have a positive impact on the international promotion of technical standards. (2) Compared with the method of expanding the user base to achieve market promotion, patent licensing has a stronger effect on technology promotion. From the perspective of market segmentation, the international market has an obvious role in promoting the internationalization of technical standards, while the domestic market has a negative effect, indicating that excessive attention to the domestic market will have a crowding effect on the cultivation of the international market. (3) Heterogeneity analysis shows that technology catching-up and imitation enterprises have a more significant effect on the internationalization of technical standards through the market promotion mechanism, and they are more inclined to occupy the international market with their superior products to drive the internationalization of technical standards. Technology-leading enterprises, transition-oriented enterprises, and innovative enterprises have a more significant effect on the internationalization of technical standards through technology promotion, and they are more inclined to drive the internationalization of technical standards through patent licensing. The research conclusions provide an important decision-making reference for the realization of the strategic goals of standard international development such as "enhancing the openness of standardization" and "coordinated development of standards at home and abroad" that China is vigorously promoting.
