运用重心研究方法对1995—2006年全国及7大区国内旅游客流量、收入重心的空间动态变化轨迹进行详细分析，结果表明：1995—2006年国内旅游收入重心呈“西北—北—东南—西北”移动，整体向北移动，国内旅游收入南北差距有明显的缩小；1995年以来国内旅游客流量重心呈“西南—西”方向移动，西南区的旅游业为我国旅游次级增长极，国内旅游客流量东西差距不断缩小．国内旅游收入重心和客流量重心的位置和变动轨迹不一致，整体国内旅游收入重心较同期客流量重心偏东．7大区国内旅游客流量、收入重心呈现出各异的时空变化特点，各区内国内旅游发展存在较大不均衡性，多表现出省区间交错发展．

Based on the gravity center method, the center-of-gravity changes of domestic tourism flow and income in China and seven regions from 1995 to 2006 were analyzed. It showed that the center-of-gravity of domestic tourism income presented “northwest-north-southeast-northwest” tendency and moved to the north as a whole. The domestic tourism income gap between northern and southern China was reduced obviously. The center-of-gravity of domestic tourism flow presented “southwest-west” tendency, and the southwest region became the sub-growth pole of domestic tourism. The difference of domestic tourism flow between eastern and western China was reduced gradually. The position and changes of the domestic tourism income and flow were inconsistency, and the center-of-gravity of domestic tourism income located more easterly than that of domestic tourism flow as a whole. The center-of-gravity of domestic tourism flow and income of seven regions changed spatially and temporally. The development of domestic tourism in different regions was quite unbalanced, and showed the staggered development among provinces.
