AbstractRecent changes on the international scene have been instrumental in the continuing evolution of US S&T policies. With the Clinton Administration these policies are entering a new phase because of the change of administration, and developments in domestic and international affairs and in science and technology themselves. The role of the Federal Government is being increased, in partnership with industry, but with political opposition from the new Congress. The policies of the Clinton Administration, if allowed to continue, are intended to reassert the competitiveness of the US economy.
