Question

请教大家以下这段英文的精准翻译！谢谢！

While the global trading system generally supports open trading arrangements, it also allows room
for substantial policy exceptions. These exceptions are quite narrow, and can be applied in a
discriminating manner. The narrowness of the product space in which policy can be applied, and
the discriminating use allows a research design that exploits relative dierences in import dynamics
- across countries and across similar products - to relate changes in import competition to industry
demands for protection. Knowing more about the use of exceptions can help us better understand
the pressures that drive trade policy, and perhaps even the benets of the wider system of restraint.
