农户环保型农资选择行为研究?——基于实验经济学

Environmentally Friendly Agricultural Materials Choice of Household Based on the Experimental Economics

本文借助实验经济学的分析方法,分析了信息传递环境、农业补贴额度与农户风险收益偏好对农户环保型农资产品选择行为的影响。实验结果表明,环保型农资产品使用量会随着实验轮数的增加而下降,信息传递的环境越透明,下降的速度越快,甚至出现了跟风现象;农业补贴可以显著提高农户的环保型农资产品使用量,并与补贴额度呈正相关,补贴与市场机制的耦合作用会使农户产生"现状偏见",即使补贴额度下降,使用量仍处在相对高水平;强调规避损失的激励政策效果要优于强调获得的激励政策,等量的损失比等量的获得对农户的感觉产生更大的影响。

With the help of analysis method of experimental economics,the article analyses the influence on householders' choosing behavior to environmentally friendly agricultural materials in the aspects of information transmission environment,subsidies and households' risk preference. The result indicates that the usage of environmentally friendly agricultural materials will decline by the increasing of experiment round. The more transparent of information environment,the faster it decreased,and even a copycat phenomenon appeared; agricultural subsidies can significantly improve the usage amount of environmentally friendly agricultural materials and correlated positively with the amount of subsidies. Subsidies and market mechanism enable 'status bias'in householders,even if the amount of subsidies decline,the using of the amount still keep a relatively high level. The effect of emphasizing avoiding loss is superior to that emphasizing gaining profit,compared with the equal obtain,loss has a greater impact on householders.
