英文摘要：

Since 1990s, the number of muhinational companies setting up R＆D institutions in China has increased year by year. These R＆D institutions have become an important force in R＆D activities of high-tech enterprises in our country, played a more and more important role in some industries, and even occupied the leading position in some areas. The author selects four types of indicators including the equivalent of R＆D personnel of foreign-funded enterprises, the R＆D expenditure of foreign-funded enterprises, the sales revenue of new products of foreign-funded enterprises, and the effective invention patents of foreign-funded enterprises to measure and compare foreign capital dependence of R＆D. The paper calculates and compares the foreign investment dependence of R＆D in China＇s high-tech industry from the perspective of industry and regional perspective, and puts forward the corresponding countermeasures.
