中文摘要：

本文在贸易引力模型的基础上,将制度因素纳入到双边贸易模型的分析框架中,并利用2000—2005年期间世界224个国家之间6492（1082×6）个双边贸易观测值组成的面板数据,从国际层面考察了制度因素对31个发展中国家对外贸易的影响。研究结果表明：发展中国家与贸易伙伴国之间的制度差距会增加贸易成本,不利于双边贸易往来;发展中国家提高金融市场的自由化程度和政府的清廉程度,有利于对外贸易的发展;发展中国家对外贸易发展与政府规模、商业自由程度表现为倒U型曲线特征;在经济发展到一定水平以后,发展中国家提高投资自由化度不利于对外贸易的发展,提高产权的保护程度有利于对外贸易的发展。因此,在不同的发展阶段,发展中国家应该根据不同制度因素的影响作用,对各种制度进行改革和调整,促进本国对外贸易的发展。
