Based on the analysis of its basic characteristics,this article investigated the disparities of Chinese service industry among the three regions(the eastern China,the western China and the middle China) and inter-provincial disparities of that in the three regions by Theil coefficient and cluster analysis.Then,major factors influencing its spatial disparity were explored by correlation analysis and regression analysis.The conclusions could be drawn as follows.1) The development of Chinese service industry experienced three phases since the 1980s:rapid growth period,slow growth period,and recovery period.From the proportion of value-added and employment,its development was obviously on the low level.From the composition of industrial structure,traditional service sectors were dominant,but modern service sectors were lagged.Moreover,its spatial disparity was distinct.2) The level of Chinese service industry was divided into five basic regional ranks:well-developed,developed,relatively-developed,underdeveloped and undevel-oped regions.As a whole,the overall structure of spatial disparity was steady in 1990-2005.But there was notable gradient disparity in the interior structure of service industry among different provinces.Furthermore,the overall disparity expanded rapidly in 1990-2005.The inter-provincial disparity of service industry in the three regions,especially in the eastern China,was bigger than the disparity among the three regions.And 3) the level of economic development,the level of urban development,the scale of market capacity,the level of transportation and telecommunication,and the abundance of human resources were major factors influencing the development of Chinese service industry.
