Detailed Answer
The trend is clear: domestic products have largely replaced imports in generic industrial scenarios (price 1/5–1/10 + faster after-sales), while imports still have advantages in special scenarios (nuclear/military/extreme environments) but the gap is narrowing. Domestic leaders (LDER/XINGJIA) continue investing in R&D, expanding the replacement scope. Enterprise procurement localization is the mainstream trend — suggest gradual replacement with case validation.
