Abstract: As the development of cyberspace represents the cutting edge of the new global economy, its size and content are likely to reflect the distribution of GDP per capita and population of the real world. In this paper, we firstly discuss the spatial-temporal distribution of Internet in China with the methods of Lorenz Curve and Gini Coefficient. Then we use the power law to analyze the domain distribution in each province, the distribution of GDP per capita and the population in each province. It was found that cyberspace is still at its high speed, and the cyberspace distribution reflects the distribution of regional GDP per capita, not the regional population. The correlations that we found between regional domain distribution and population was low, although that between the regional domain distribution and regional GDP per capita was much higher, confirming our general intuition that the economic development of region is all the more important in explaining cyberspace size. The power law relations that we have examined all display the tendency for the number of small events -regional domain distribution, regional population, and regional GDP per capita -to be less than what power law predicts, this can easily be explained by the smaller domains having not yet reached maturity. We illustrate the plausibility hypothesis that the largest domains approximate power law while the smaller domains are growing towards this steady state. The differences in power law that we computed between these two sets confirms this notion. Finally, the paper gives the developing speed and the years to reach the mature and steady state of Internet in China.
