Abstract: The authors think that the addition of entropy constraint to the classical productive forces distribution theory accord better with facts. In this paper, we introduced a productive forces distribution model with entropy constraint and proved that the solution of this problem in some conditions is a gravity model. The importance of this notion is evident, because it shows that in the economic field there exist gravity phenomena.

Key words: entropy constraint, productive forces distribution model, gravity model

摘要： 本文认为:在经典生产力配置模型中引入熵约束能更好地反映实际情况。因而,本文提出了具有熵约束的生产力配置模型。证明了它的解符合引力模型。表明在经济问题中存在引力现象。
