Public Support for Private R&D: The Case of the Research Tax Credit
本文分析了美国研发税收抵免政策对工业研发的刺激效果，并比较了支持单个企业研发与鼓励企业联合研发的优劣，认为联合研发可能更有效。
The U.S. government has long included in its tax code various special provisions designed to stimulate industrial R&D. In 1981, those provisions were substantially augmented by a special R&D tax credit, and various proposals are now under consideration to relax the antitrust statutes in order to encourage research through joint ventures. The case for any of these measures is difficult to establish, being based on assumptions that are not readily tested in objective terms. Nevertheless, one point is fairly clear: As between stimulating industrial R&D by individual firms and stimulating R&D joint ventures of such firms, the joint venture approach appears superior in its likely results.
