摘要
投资和消费作为经济增长的主要动力,对我国各省区经济贡献差异明显。本文利用重心模型和探索性空间分析法对1978～2017年我国30个省区经济增长动力的时空演变特征及相关性进行研究,主要得出以下结论:(1)支出法核算下,目前我国经济成长整体尚处于向成熟推进阶段,经济重心经历了"西南——东南——东北"的离移;(2)投资对各省区经济贡献呈现出了"东高——中高——西高"演变过程,空间上表现出了"高散——随机——低低"的集聚;(3)消费对各省区经济贡献经历了北京和广州为中心的消费圈、发展滞后地区高消费和西部地区高消费的演变过程,空间上呈现出了"高散——随机——集聚"的演变特征。
As a source of economic growth,investment and consumption have made significant differences in the economic contribution of various provinces and regions in China.This paper uses the gravity center model and spatial exploratory analysis to study the temporal and spatial evolution characteristics of the economic growth source dynamics of 30 provinces in China from 1978~ 2017.Mainly draw the following conclusions:(1)under the expenditure method,the overall situation of China is still in the stage of maturity,and the economic center of gravity has experienced the migration of“southwest-south-easteast”;(2)the contribution of investment to the economic development of various provinces and regions in China'shows the evolution process of“east high-medium-high-west high”,and spatially shows the accumulation of“high dispersion-random-low-low”;(3)the contribution of consumption to the economic development of China's provinces and autonomous regions has experienced the evolution of consumption circles centered on Beijing and Guangzhou,high consumption in lagging regions,and high consumption in the western region,showing the characteristics of“high dispersion-random-aggregation”in space.
