国内贸易、对外贸易与交易效率关系的实证研究

Empirical Research on the Relationship among Domestic Trade,Foreign Trade and Transaction Efficiencies

本文收集1997～2002年中国30个省市的相关数据对交易效率、硬交易效率和软交易效率进行了度量,并搜集这30个省市的国内贸易、对外贸易和人均GDP数据,对各省国内贸易和对外贸易与交易效率之间的演进关系进行了计量分析。分析结果表明,无论是国内贸易还是对外贸易都随着交易效率的演进而演进,且在1997～2002年间,软交易效率比硬交易效率对贸易的影响更大。这表明,要推动我国国内贸易和对外贸易的进一步发展,从多方面对交易效率进行改进是十分重要的。

This article measures transaction efficiencies including the hard efficiency and the soft efficiency with relevant data across 30 provinces in China within 1997 and 2002 and analyzes econometrically the evolution relationship among domestic trade, foreign trade and transaction efficiencies using fixed effect panel data model. The result shows that both domestic trade and foreign trade increase with the increase of trade effieieneies. Moreover, the soft trade efficiency affects trade much more than the hard one does. The analysis implies that improving trade efficiencies is necessary to stimulate further development of domestic and foreign trade.
