英文文献摘要：
This study examines the relationship between agricultural profits and farm household wealth across locations and farm sizes in U.S. agriculture. Farmland has out-performed non-farm investments over the past decade. Thus, households may want to keep their farmland to build wealth, even if it requires them to earn off-farm income.

本研究考察了美国农业中不同地区和农场规模的农业利润和农户财富之间的关系。在过去十年里，农田投资的表现超过了非农业投资。因此，家庭可能希望保留他们的农田来积累财富，即使这需要他们赚取非农收入。
