英文文献作者：Gomez, Miguel I.,Zhang, Liying
英文文献摘要：
This paper evaluates the impact of increasing concentration of the livestock sector on the economic welfare of rural Illinois. A pooled time-series, cross-sectional model is developed to study the dynamics of structural changes in hog production for the period 1981-1997. The model tests the efficient-market hypothesis on local rural economies.
