New kinetic energy is the main driving force of the“new economy” and a important way to realize the high-quality development of Chinese economy. This paper measures new kinetic energy index at the level of the whole nation, four regions and provinces during 2015-2018. The study finds that: (1) China"s new dynamic energy has made remarkable progress and is accelerating to generate huge economic benefits. The main performance can be listed as follows. Firstly, the technological progress and rapid accumulation of intangible capital lay the foundation for the cultivation of new dynamic energy. Secondly, the transformation and upgrade of industrialStechnology is effective. Finally, the development of new business forms is growing rapidly. However, the improvement of business environment to promote the growth of new kinetic energy is not obvious. (2) The growth of new dynamic energy in the eastern part is remarkable, and the growth of new dynamic energy in the central and western part is accelerating, but the growth of new dynamic energy in the northeastern part is still lingering. (3) Beijing and Shanghai are the engines of new power growth in China"s economy, but Xinjiang, Hainan, Gansu, Heilongjiang and other provinces still need to improve.
