西方政治家一向主张进行“绿色”国民收入核算。美国总统克林顿于今年地球日宣布，美国将力图在进行国民收入核算时更全面地考虑环境问题。欧共体也正着手实施一项整个共同体范围内的类似计划。然而，统计学家能够为国民收入核算提供的资料与政治家的期望之间存在着巨大差异。 Western politicians have always advocated “green” national income accounting. U.S. President Bill Clinton announced on Earth Day this year that the United States will try its best to consider environmental issues more fully in the process of making national income accounts. The EC is also embarking on a similar program within the community as a whole. However, there is a huge difference between what statisticians can provide for national income accounting and what politicians expect.
