英文摘要：

The division of work in global R＆D network produced when the division of global network went deep into the single value-added chains. From the angle of embed barriers and upgrade dilemma of multinational corporations, this article firstly explores the favorable and unfavorable factors which have influenced the multinational R＆D investment.
