美国中西部生态农业实践采纳动态：互补性与采纳强度的理解

摘要

We investigate the complementarity and adoption intensity of ecological agriculture practices (EAPs) among Midwestern farmers, with a focus on environmental stewardship and profit-maximization motives. Using survey-level data on farmer characteristics in the US Midwest, we employ multivariate probit (MVP) and Poisson regressions to assess these linkages. The MVP results indicate that the degree of complementarity between EAPs varies in magnitude, with the highest complementarity between diversified crop rotation and integrated crop-livestock systems (50%). Regarding the adoption intensity, we find that farmersÕ decisions are influenced by both ecological and economic interests, with environmental stewardship motive playing a greater role.
