英文摘要：

Basic research plays an important role on economic growth. By analyzing the R＆D indicators of 28 repre- sentative countries and regions in OECD database from 2005 to 2010, it finds that China＇s R＆D investment structure is unreasonable and its basic research input of R＆D ratio is too low, especially for the enterprises. The empirical analysis on the panel data shows that basic research investment relies heavily on government funding, and the development of capital market positively influences basic research intensity. Moreover, intellectual property protection and FDI can also promote basic research investment.
