Abstract: This paper constructs an evaluation index system of economic growth kinetic energy index, calculates the economic growth kinetic energy index of 30 provinces in China from 2009 to 2018, and empirically calculates the regional gap of economic growth kinetic energy and the dynamic evolution trend of its distribution. The results are as follows: (1)The economic growth momentum levels of provinces show a fluctuating and rising development trend, and the regional differences are obvious between the east and the west. (2)The overall regional gap of China's economic growth kinetic energy shows a narrowing trend. From the interregional perspective, the gap in the eastern region is the largest and the gap in the central region is the smallest. From the intraregional perspective, the gap between the eastern and western regions is the largest, and the gap between the central and western regions is the smallest. From the perspective of disparity contribution rate, the interregional disparity is the main source of regional disparity in the transformation of economic growth kinetic energy, while the contribution rate of intraregional disparity and supervariable density is small. (3)The regional disparity of economic growth kinetic energy conversion in different regions of China fluctuates, but it shows a downward trend as a whole. There is a bipolar or multipolar trend in all three regions, especially in the central region.

摘要： 本文构建经济增长动能指数评价指标体系，测算2009—2018年我国30个省份的经济增长动能指数，考察其地区差距及分布动态演进趋势。研究发现：（1）各省份的经济增长动能转换水平整体呈现波动上升态势，东西差距显著。（2）总体地区差距呈现缩小趋势，从地区内差距来看，东部地区内差距最大，中部地区内差距最小；从地区间差距来看，东西部地区间差距最大，中西部地区间差距最小；从差距贡献率来看，地区间差距为主要来源，地区内差距和超变密度的贡献率较小。（3）我国整体经济增长动能转换地区差距出现波动式下降，三大地区均存在两极或多极化现象，中部地区尤为显著。
