Abstract: Based on the study of the relationship between R&D expenditure and patent output, and funding-performance structure, this article builds a theoretical framework about relationship of R&D organizational structure and patent output. We measure the diversification of unilateral and cross organizational structure of R&D expenditure in U.S., analyses the relationship of organizational structure and patent output. The results show that the degree of diversification is at an intermediate level, the unilateral structure showed “inverted U” evolution curve and the cross structure evolution showed alternating increase and decrease, the funding structure of R&D expenditure impact to patent output by the R&D intensity, and the relationship between the structural diversity of R&D expenditure and patent output showed “inverted U” or “U-type” curve.
