农户秸秆处理行为特征与影响因素分析

Characteristics and Influencing Factors of Farmers’Straw Treatment Behavior

传统研究认为农户拥有土地使用权的稳定性是能否激励农户对土地采取长期投资的一个重要影响因素。基于具有代表性区域的随机农户调查数据,揭示了在经济环境改变后,农户家庭收入结构出现巨大变化而土地社会保障功能下降的情况下,农户对土地的投资行为的变化。以农户的秸秆处理行为为例,采用问卷调研数据,运用Probit模型进行探讨。结果发现:农户非农收入占整个家庭收入比例不断增加后,农户对土地的投入更倾向于采用“劳动时间节约型”方式。秸秆处理方式更倾向于焚烧、丢弃、出售,而土地规模的扩大更利于秸秆还田技术的运用。通过不断延长土地承包期等增强农户土地权利的方式来激励农户对土地的长期投资作用有待进一步验证。

The traditional study holds that the stability of land tenure as an important factor can encourage farmers adopt long-term investment.This study expects to use the Probit model to reveal the change of farmers’investment behavior by using the random farm household survey data based on the representative region and taking the straw dispose behavior as an example.The results of our study indicate that,although farmer’s right of land has increased steadiness,but along with the change of farmer family’s incomes structure and the losing of farmland insurance function,farmer’s decision for the investment of farm land is apt to‘labour time saving types’,so the farmer’s straw dispose behavior often adopt burning,discarding and saling,and the enlargement of land scale will conducive to impel farmer to apply straw returning technology.So if still extending the stability of land tenure to encourage farmer adopted long-term investment will had little effect.
