摘要
传统的进口需求方程设定可能难以深入揭示对进口的影响机制。本文基于支出法GDP的分类框架,并采用前沿的ARDL边限检验法,实证研究1997年1季度至2014年3季度期间进口需求方程的长期、短期关系,以更好地分析各部门经济活动对进口的影响差异。结果表明:长期内,进口与出口、消费、投资、政府支出、人民币实际有效汇率(REER)等变量之间存在协整关系,各支出需求变量无弹性;短期内,出口、消费、投资等变量对进口有显著的影响。各支出需求变量在长期、短期上的弹性系数有着明显差异,意味着各经济部门的支出需求有不同的进口内容。REER在长期和短期内负向影响进口,无弹性。论文提出了若干有针对性的启示和政策建议。
