Andrea’s Christianopolis is “the third pearl after Utopia and Sun City” in the utopian socialism history. This book embodies Andrea’s ondemand distribution thought,in which he thinks public ownership is the basis of the distribution of ownership, and attention should be paid to the important role of science and technology. Social production should be planned. The means of production and subsistence are distributed according to need. Due to the limitations of history, his distribution according to need is full of equalitarianism and asceticism color.
