金融发展对对外贸易的影响通常被隐含在金融发展对经济增长的一般影响中,鲜有直接探索金融对贸易的影响及机制的文献。基于此,在理论上,本文认为,金融发展与对外贸易之间存在长期均衡关系,金融发展长期内通过动员储蓄和优化资源配置增加对外贸易的规模,同时改善贸易结构。在实证上,基于我国1995年1月至2006年9月的月度数据,采用边限协整检验方法和误差修正模型(ARDL-ECM)进行估计,实证分析结果支持本文的理论假说。另外,本文还发现,金融发展对外贸的长短期影响存在差异:短期内存在抑制效应,通过加大金融支持力度改善对外贸易的政策存在超过三个季度的时滞;长期存在规模和结构上的促进效应。本文的发现有助于人们理解信贷政策对贸易的动态影响。
<<Using the data of foreign trade and financial development in China from January,1995 to September,2006,this paper estimates the relation of the foreign trade and financial development by means of autoregressive distributed lag model and the bound test. The result indicates that they have an equilibrium and stable relationship in the long term,that is,the financial development increases the foreign trade and improves its structure through stimulating of saving and allocation of resource,but the effects reverse in the short term. Meanwhile,the economic growth has the same effects on foreign trade as the financial development,and the real exchange rate has no significant effect on foreign trade.
