《AE》| Hou et al：风险偏好、知识、土地整理和景观多样化对农药使用的影响

 摘要：研究人员花费了大量精力来确定影响农药使用强度的因素。然而，很少有研究比较这些因素的相对重要性。本研究通过评估中国的激励实验数据、农场调查数据和遥感数据，研究了可能影响农民农药使用决策的四类因素。我们的研究结果表明，土地多样化对农民农药使用的影响最大。与水稻密集程度最高的景观类型相比，水稻密集程度较低的系统会导致农民减少对中稻的喷洒。由于小规模农场仍主导作物生产，因此农药使用强度高与土地破碎化有关。农民的综合虫害管理知识对农药使用有显著影响。我们还发现损失和模糊偏好，而不是风险偏好，更有可能影响农药使用强度。

Abstract:Researchers have spent substantial effort to identify factors influencing pesticide use intensity. However, few studies have compared the relative importance of these factors. This study examines four categories of factors that potentially influence farmers’ pesticide use decisions by evaluating incentivized experiment data, farm survey data, and remote sensing data in China. Our results suggest that land diversification has the largest effect on farmers’ pesticide use. Compared with the most rice-intensive landscape type, less rice-intensive systems cause farmers to spray less on middle rice. Heavy pesticide use intensity is associated with land fragmentation as small-scale farms still dominate crop production. Farmers’ integrated pest management knowledge has significant effects on pesticide use. We also find that loss and ambiguity preferences, rather than risk preferences, are more likely to affect pesticide use intensity.

Key words: China, land consolidation, landscape diversification, loss and ambiguity aversion, pesticide use, risk preference
