中国经济发展进入新常态,基本特征是速度变化、结构优化、动力转换。深入认识这三者的内涵及相互关系,是我们全面理解经济发展新常态的重要基础,也是我们主动适应新常态的基本要求。一般来说,经济发展进入新常态,速度变化、结构优化、动力转换相互影响。经济增速的变化是主要动因,能够直接影响到结构、动力的改变,如果没有一个相对稳定的经济增长速度,结构优化升级、新的动力机制重塑都要受到制约。但同时,结构优化、动力转换也会反作用于经济增速, China’s economic development has entered a new normal with the basic characteristics of speed change, structural optimization and power conversion. A thorough understanding of the connotation and mutual relations among the three is an important basis for our comprehensive understanding of the new normal of economic development and a basic requirement for us to take the initiative to adapt to the new normal. In general, economic development has entered a new normal, with its speed changing, structural optimization and power conversion interdependent. The change of economic growth is the main driving force, which can directly affect the structural and dynamic changes. Without a relatively stable rate of economic growth, structural optimization and upgrading, the reform of the new dynamical mechanism should be constrained. But at the same time, structural optimization and power conversion will also react to economic growth,
