收敛区间

From the industry to observe,the author discovers that the regional gap of the secondary industry was the primary contributor,but the rate of was descending.The third industry was becoming the important contributor.The industry structure adjusting and the agglomeration of the third industry and the secondary industry are the primary reason of the forming of the disparity of between the east and the rest areas.In the 1978 to 2005,the absolute convergence of economic growth didn't occur,the other way round,the club convergence of economic growth occurred in the east and in the middle.The speed of the economic growth in the east was higher about 1 centigrade than the middle and the developing west,and was higher about 2 centigrade than the west.

从以省区为单元的中国地区经济发展差距形成的产业构成来看，第二产业的地区差距长期以来都是中国地区经济发展差距的主要贡献者，居主导地位：但是随着第三产业产值比重的提高和第三产业地理集聚的非均衡性扩大(1990年以后)，第三产业的地区差距正逐渐演变为以省区为单元的中国地区经济发展差距形成的主要贡献者。1978-2005年期间，中国地区经济增长并没有出现绝对收敛趋势，而是表现为东中部地区内部的"俱乐部"收敛。1978-2005年东部地区经济增长速度比中西部地区更快，东部地区平均经济增长速度比中部地区高1个百分点左右，比西部地区高接近2个百分点，地区间经济增长速度存在显著的差异。
