Since China entered WTO,especially since from 2007,China's foreign trade environment has gotten great changes:domestically,foreign trade policies adjust, duty draw-back decrease,RMB increase in value sustention,new labor law takes effect,internationally,the states arose serious Supreme Mortgage Crisis which further caused financial crisis,euramerican countries impose technique barrier and enhance protectionism;under such harsh situation,what course to follow puzzle personnel of medium and small foreign trade enterprises.

自从加入WTO到现在，特别是从2007年起到现在，我国的外贸环境发生了很大变化：国内方面，外贸政策调整，出口退税减少，人民币持续升值，新的劳动法的实施等等；国际方面，美国发生了严重的次贷危机，以及由此引发的金融危机，欧美国家实行的技术壁垒和日益严重的保护主义；在此种严峻形势下，我国的外贸出口企业何去何从，困扰着广大企业人员。本文应用SWOT理论，对AB外贸公司的内外环境进行了分析，从全球价值链高环介入的方面，进一步提出了AB外贸公司应该提升在价值链中的地位的战略，改变低环介入价值链的方式，逐步转变为从高环介入，核心思想是要提高外贸企业的核心竞争力。
