30年来中国人口、经济、产业重心演变的轨迹及其对比

通过对1978-2008年中国人口、经济、产业重心演变轨迹的比较可知，人口重心演变轨迹是前20年缓慢、稳定地向西南移动，在2000年以后向东南方向移动，比经济重心的移动幅度小；分产业结构看，第二、第三产业重心向东南方向移动，而农业重心则表现为无规律性变化。第二产业分布的重新调整和第三产业的发展是推动经济重心移动的主要因素。因此，为缩小地区差距、促进区域协调发展，一方面要促进落后地区快速发展，另一方面也要建立起落后地区分享繁荣地区经济发展成果的机制。

Research on the Shifts of Gravity Centers of China's Population, Economy and Industry in the Past 30 Years and Contrastive Analysis of Them

The shifts of gravity centers of China＇s population, economy and industry in 1978--2008 are compared in the paper. The findings indicate a slow and stable shift in the first 20 years to the southwest in the gravity centre of the population, and to the southeast after the year 2000, a smaller movement than that of economy; as far as industrial structure is concerned, the focus of the second and tertiary industries move to the southeast, while the change of agricultural one irregular. Re-adjustment of the secondary industry distribution and acceleration of the tertiary industry serve as the main factors to promote the economic shifts. In order to reduce regional disparities and promote balanced regional development, backward areas should speed up their progress, whereas a mechanism must be set up for the areas to share economic fruits of the prosperous regions.
