外贸结构的非均衡机理探索

经济结构呈现非均衡的常态特征。在市场不完全、信息不充分、外生条件不统一等因素的制约下,一国外贸结构形成的资源配置效率通常低于均衡世界里的帕累托最优效率,是一种“次优”均衡;这种非均衡模式可能在受到外在冲击时或通过内生演进的方式发生改变,并通过进出口商品结构、贸易方式结构等表现出来。外贸结构非均衡的核心特征是进出口商品的要素密集度高低,并与比较优势和后发优势联系在一起,成为外贸结构非均衡演进规律的主要内容。

An Approach into the Disequilibrium Mechanism of Foreign Trade Structure

Disequilibrium is a kind of normality in economic structure. Restricted by the imperfect market, insufficient information, dis-uniform exogenous conditions and some other factors, the efficiency of resource distribution in a country's foreign trade structure is inferior to the Pareto Efficiency which existed only in the equilibrium world. Such a disequilibrium mode maybe alter when shocked by outside force or through endogenetic evolving and showed by the structures of imports & exports, trade modes etc. The core character of the foreign trade disequilibrium is the density of factors included in the imports & exports. It is the main content of foreign trade disequilibrium evolving when related with comparative advantages and advantages of backwardness.
