The allocation of land right in modern times needs to be restudied with an improved research method. Three factors, namely, public land, one piece of land shared by two owners and households without land have great impact on the statistics of the allocation of land right, which have usually caused the overestimate of the intensity of land right allocation. Removing the impact of these factors, this paper modifies Gini Coefficient of land right allocation in some regions and finds that the overestimated intensity of land right allocation in southern regions such as Jiangsu, Zhejiang and Guangdong declines to a great extent. In terms of the intensity of land right allocation in modern China as a whole, there is no great difference between the north and the south, and the overall allocation is quite average in most areas.
