文章运用双约束引力模型和交叉熵法对我国30个省、自治区、直辖市42部门产品和服务的省间贸易量进行了估算，通过聚类分析比较了各省间贸易在经济和贸易中的比重。得出该比重在我国各省之间的差异较大，尤其是在东部沿海地区各省之间相差很大。同时，各类地区处于优势或处于劣势的指标也均有所不同。从自然资源、人口规模等六个角度分析了该现状的原因，并对我国省间贸易的发展提出了建议，包括充分发挥市场和政府的积极作用等。
文章運用雙約束引力模型和交扠熵法對我國30箇省、自治區、直轄市42部門產品和服務的省間貿易量進行瞭估算，通過聚類分析比較瞭各省間貿易在經濟和貿易中的比重。得齣該比重在我國各省之間的差異較大，尤其是在東部沿海地區各省之間相差很大。同時，各類地區處于優勢或處于劣勢的指標也均有所不同。從自然資源、人口規模等六箇角度分析瞭該現狀的原因，併對我國省間貿易的髮展提齣瞭建議，包括充分髮揮市場和政府的積極作用等。

With the double constrained gravity model and cross-entropy method,this article estimated inter-provincial trades among 30 provinces in China,with 42 sectors distinguished. Based on the cluster analysis,the inter-provincial trade propor-tion in economics and trades in different provinces was compared. It can be concluded that this kind of proportion varies a lot among different provinces, especially among those in the eastern coastal area. Meanwhile, perfect or dissatisfying indicators are always various among different region categories. The cause analysis was given in six perspectives,such as natural resourc-es,population scale,etc. Some suggestions were put forward,like making full use of the positive function of the market and government.
