Composition of R&D expenditures and firm performance

The explosion of research and development (R&D) expenditures in China brings a puzzling fact that the proportion of research in R&D is extremely small, and thus the proportion of development is large. This article distinguishes research from development in R&D and investigates the heterogeneous effects of the two components on the performance of Chinese listed firms. Using a generalized propensity score matching approach with continuous treatments, we present non-linear relationships between R&D composition and firm performance. While development-oriented firms benefit more from an increase in profit than a growth in productivity, orientation toward research contributes more to productivity gains than to profitability. Research and development activities are found to be complementary in promoting firm performance. The results suggest the existence of optimal proportions of the components of R&D for maximizing firm performance.
