英文文献作者：Ferguson, Carol A.,Halloran, John M.,Nakamoto, Stuart T.
英文文献摘要：
Measurement of agriculture's economic contribution must consider possible replacement of farm production by imports and induced loss of forward-linked sectors. Sequential extraction, an input-output technique, is applied to the food system to assess total economic activity attributable to agriculture. The approach is demonstrated using Hawaii state data.
