FDI对国内投资与经济增长的冲击效应分析——基于VAR模型的分析

20世纪80年代以来，外商直接投资已成为发展中国家获得外部资源的主要渠道，已成为中国经济发展的一个重要经济增长点。文章通过协整检验发现，FDI流入分别对经济增长与国内投资产生正向、负向作用，除中部地区外，这一趋势还将在今后一段时间持续。接着，通过邹检验发现，在外商直接投资的外部冲击下，中国及东、中、西部的国内投资及经济增长分别在1992年，1989年，1990年，1998年发生结构性变化。再次，通过Granger因果检验与脉冲响应函数分析发现：中国及各地区国内投资在外商直接投资的投资下呈现较为一致的变化态势，但中国各地区经济增长在外商直接投资的冲击下呈现各异的变化特征。
