R & D Spillovers and Recipient Firm Size
用生产函数方法研究小企业如何创新，发现小企业从大企业研发中心和大学获得研发溢出，且这种溢出对小企业创新的促进作用比大企业更关键。
The findings in this paper provide some insight into how small firms are able to innovate. Using a production function approach to relate knowledge generating inputs to innovative output, the empirical results suggest that small firms are the recipients of R&D spillovers from knowledge generated in the R&D centers of their larger counterparts and in universities. Such R&D spillovers are apparently more decisive in promoting the innovative activity of small firms than of large corporations. Copyright 1994 by MIT Press.
