The article provides an important analytical framework: the true motivation of localization policies is often political anxiety rather than pure economic or security rationality, so the actual implementation strength may not match the announced stance. Foreign trade practitioners can approach assessment from three angles. First, examine the dependence structure—your customer's country's true reliance on your product or technology determines your bargaining space. Second, examine cost differentials—if the cost of domestic substitution is far higher than imports, policy implementation often meets resistance or exemptions appear. Third, examine policy reversal risk—if the other side pushes localization hard but the cost is too high, they may instead reopen or shift toward diversified procurement, actually creating opportunities. Mastering these analytical bases helps make more accurate predictions in quotation strategy and delivery scheduling, rather than being simply led by policy announcements.
