现代意义上的政府采购是国家机关或行使国家权力的事业单位和社会团体利用商业机制，从独立于政府机关的供应商处获得货物、工程和服务的行为。对外经济援助的特殊性导致了其政府采购的特殊法律特征。相较于已有200多年历史的西方发达国家的政府采购法，我国的政府采购可谓是蹒跚学步，而我国现在又面临着履行入世承诺、开放政府采购市场和加入WTO的《政府采购协议》的巨大压力。因此，借鉴和吸收新进国家和地区的理论和立法经验，明确对外经济援助政府采购合同的性质、对行政诉讼法进行修改、或是出台《政府采购法》的司法解释和实施细则，完善《政府采购法》或是建立专门的对外经济援助政府采购法及其相关司法解释，建立符合我国国情的对外经济援助政府采购法律机制已显得十分重要和迫切。目前我国政府采购法律制度不够完善，现有的专门的援外政府采购法规仅限于《政府采购法》和《招标投标法》，及商务部对外援助制定的若干规章制度，缺乏系统的政府采购制度。这种体制上的欠缺十分不利于援外采购计划的实施，容易导致效率低下，也容易滋生腐败，阻碍我国外交政策的实施，最终可能影响到我国在国际上的声誉和地位。目前， 基本法律相冲突、政策功能作用比较差，信息披露不规范、信息化水平落后，救济、监管制度不健全，已经成为制约对外经济援助政府采购健康持续发展的主要因素。而健全的对外经济援助政府采购制度不但可以使有限的资金获得最大程度的使用效率，而且有利于促进公平竞争，促使商品、货物、工程、服务的采购质量的提高，增强本国供应商的国际竞争力，同时可以使援外政府采购处于公平、公正、公开的环境中，有效地抑制腐败的滋生，提高对外经济援助政府采购行为的公信力，提升对外经济援助中政府采购在社会公众中的形象。更好的保障国内纳税人的权益，提升对外经济援助的国民认同感等。因此，健全我国对外经济援助政府采购法律机制是十分必要和急迫的。我国应该从建立完善的援外采购主体制度、援外采购的方式、程序控制以及援外采购的救济制度这三个方面进行努力，尽快建成科学、有效的援外采购监督机制，实现更有效率和意义的援外采购。
