On January 3, GLONGHUI (688056.SH) said during a survey with specific targets that at present, large-scale implementation of domestic substitution requires a process. Relatively speaking, the proportion of imported products is relatively high, and the market space for domestic alternatives will be relatively large. Moreover, it is true that some customers in the market prefer domestic products, especially in industries such as semiconductors that are more sensitive to trade frictions. However, in response to the promotion of domestic substitution policies, many importers will respond by means of domestic OEM, OEM sales, etc., and customers will also need some time to accept and verify the actual use and application of domestic products. Customers will also comprehensively consider various factors such as instrument performance, instrument brand, and service response speed. In the long run, this positive impact and trend of domestic substitution exists.
