外商直接投资与对外贸易技术溢出效应比较——基于面板因果关系的研究

Comparison between Technology Spillover in FDI and International Trade—Based on Panel Causality Analysis

开放经济中,最主要的国际经济关系是国际投资和国际贸易,二者都对东道国的产业有技术上的影响。文章运用面板单位根检验、协整检验以及误差修正模型等现代计量经济学方法,考察外资和进出口对中国整体技术水平的影响。结果显示FDI和技术进步互为长期和短期因果关系,对外贸易是技术进步的长期和短期原因,没有证据显示外商直接投资和进出口有长期稳定关系。

Both foreign direct investment(FDI) and international trade have technology spillover effect on economic development.This paper uses econometric analysis such as unit root test, causality test and error correction model of panel data to study the relationship between FDI, international trade and technology progress.The results show that FDI and technology progress have long-term and short-term causality relationship, while international trade has both long-term and short-term effect on technology progress.N...
