我国水稻种植户风险偏好：理论模型与定量测算

为深入了解我国不同地区水稻种植户风险偏好类型和风险偏好程度,推动粮食生产稳定发展,基于预期效用函数构建理论模型,采用面板数据模型进行回归估计,利用回归结果测算2008~2015年我国23个省市以及分东部、中部、西南、东北四个区域的水稻种植户风险偏好指数。结果表明：我国不同地区水稻种植户都是风险规避者,并且水稻产出越大的地区,农户风险规避程度也越高。因此,对于风险规避的水稻种植户而言,降低产量风险是实现稳粮增收的有效管理手段。由此从加强产量保险推广、增加政府公共品供给、规范农资市场等方面提出了相关建议。     

Hierarchy-degree of Gray Relationship Ddecision of Land Investment Based on Cloud Model

The competition in the land market is drasticly increasing, which demands much higher scientificity and accuracy in the decision. The land investment decision system is a non-linear gray system and the traditional appraisal methods have some limit in appraising it. It uses cloud model and the uncertain illation based on the cloud model, translates the qualitative appraisal of the factors level into quantitative scores, achieves the transition between a linguistic term of a qualitative concept and its numerical representation ; and further merges the degree of gray relationship theory to appraise the comprehensive level of the objects. So the new decision mode is set up. Through an example analysis and contrast study, the validity of the method is validated. The application of cloud theory in the decision field will affirmatively improve the decision level.
