The firm obtains the benefits from the R&D like the reduction of the production cost or new technology. However, the firm has the risk of the spill over in R&D technology to the other firms. This paper analyses the effects of the subsidies for the R&D on the level of the R&D, outputs, prices and welfare with the consideration of the spill over in the technology of R&D. We show the following results. If the degree of the spill over is small, R&D subsidies by home country government increase the R&D and output levels of the home country firm and decrease those of foreign country firms. However, if the degree of the spill over is large, R&D subsidies by hone country government increase not only the R&D and output levels of the home country Srm but also those of foreign country firms.
