进入21世纪以来,中国的互联网事业得到了飞速发展;但同时互联网发展的区域差异仍表现得十分明显。采用σ-收敛、β-收敛和俱乐部收敛3种分析方法,对1997~2008年期间中国(港澳台地区除外)互联网用户增长的收敛性进行了探析,并对影响互联网普及率的关键因素进行了条件β-收敛的检验。结果发现,中国互联网用户增长的省际差异变动存在着较为明显的σ-收敛和β-收敛。控制人均GDP、城镇化水平、基础设施水平、受教育程度、对外开放度、地理位置等变量后,地区间存在条件β-收敛。东、中、西三大区域存在着较为显著的俱乐部收敛趋势,收敛速度则表现为东部慢于中部,中部慢于西部。
Since the late 1990s, Internet has maintained a dramatic growth in China. However, it is noticeable that disparities among regions in regard to Internet development are very distinguishing. This paper conducts research to explore from 1997 to 2008, how the process in regard to the growth convergence of Internet users among China's provincial areas ( Hong Kong, Maucao and Taiwan excluding) transformed, that is based on three measures, i.e., sigma convergence, beta convergence and club convergence. Moreover, the research adopts conditional beta convergence to examine the key factors which might have the influence on the utility of Internet among regions. The study suggests that during this period, distinct sigma and beta convergence exist in the growth of Internet users among China's provincial areas. By properly introducing an array of control variables, such as per capita GDP and the level of development in aspects of urbanization, infrastructure, education, openness, and geographical location, It's find out that the growth is less rapid in areas where the Internet has broadly been adopt, if in other less developing areas, vice versa. The result as well shows such growth can be categorized as conditional beta convergence. Furthermore, there is clear evidence of club convergence among the three regions of China. Each region demonstrates their capability to stable the convergence internally with the different speed. The growth in eastern regions is the least rapid while in western regions, the growth is the fastest.
