The word “decisive” holds important implications for key resources – including fuels, financial capital, and, of course, the currency – that historically have been subject to state-administered pricing. Rhetorical flourishes have always been an important signaling mechanism for major policy changes – think of Deng Xiaoping’s “reforms and opening up” of the late 1970’s.
“决定性”一词对关键资源有重要影响——包括燃料、金融资本，当然还有货币——过去这些资源都由国家指导定价。用词永远是重大政策变化的重要信号——比如20世纪70年代末邓小平所提出的的“改革开放”。三中全会用“决定性”一词给基于市场的道路定性，意义类似。
