Factors Influencing a Farmer's Decision to Invest in Long-Term Conservation Improvements
研究了20世纪80年代影响美国堪萨斯州农民投资长期保护性改良措施的因素，发现农场规模、收入、类型和耕作方式有影响，而政府项目参与无显著作用。
This investigation considers factors affecting the investment in long-term conservation improvements during the 1980s. A sample of 541 Kansas farms was used to investigate the effects of various factors on the probability and expected level of conservation investment. The results suggest differences in farm sizes, incomes, and types and farming practices influence conservation investment decisions. Farmers whose farms are corporately organized make larger conservation investments. Farmers who are older invest less in conservation. Participation in government programs does not affect the investment in long-term conservation improvements. Conservation investment fell dramatically throughout the 1980s.
