中文摘要：

“常态”是较长时期中社会发展比较平稳的状态，具有稳定性、长期性与整体性三大特征。人类社会将经历旧常态、转型社会与新常态三个不同的发展时期。未来不确定性决定了只能通过“回头望，而不是向前看”来判断社会是否进入常态，因而常态是一个历史概念。现阶段，世界与中国的经济与人口并未进入新常态，而只是处在由旧常态到新常态的转型时期，稍有不逊，中国经济就有陷入“中等收入陷阱”的极大风险。中国较少制度红利而较多制度亏空，消减制度亏空，继续释放市场与社会活力，中国经济继续增长的潜力还是巨大的。

英文摘要：

＂Normal state＂ is a relatively stable state of social development over a long period of time, with three main features ： stability, durability, and totality. Human society will experience the three stages of development ： the old normal state, social transformation, and the new normal state. Uncertainty about the future determines that we can only ＂look back＂ instead of ＂looking ahead＂ to decide whether the society has entered the normal state, therefore the normal state should be a historical concept. At the current stage, the world＇s and China＇s economy and population have not entered the new normal state, but located in the transitional period between the old and the new normal states. Any tiny carelessness might plunge Chinese economy into the tremendous risks of ＂medium-income trap＂. China offers little systematic bonus, showing more systematic deficits. By reducing systematic deficits and continuing to release market and social vitality, Chinese economy will get tremendous potential for sustained growth.
