This system has evolved through four stages, balancing government guidance and market demand while ensuring financial stability [3][4] Yuan Exchange Rate Analysis Framework - A "3+1" framework is established for analyzing the yuan's exchange rate from long, medium, and short-term perspectives, incorporating institutional regulation.
