基于农户层面的耕地经济产出价值研究

RESEARCH ON THE ECONOMIC OUTPUT VALUE OF CULTIVATED LAND BASED ON PEASANT HOUSEHOLD PANEL

在采用收益还原法对研究区农户水田、旱地样本经济产出价值进行核算的基础上,运用相关分析和C-D生产函数考查农户行为对耕地经济产出价值的影响作用情况,并根据行为动机理论构建农户行为对耕地经济产出价值的影响机理。结果表明:农户水田、旱地样本地均经济产出价值之间存在较大波动,且水田样本价值普遍高于旱地样本;水田、旱地样本经济产出价值在不同程度上受到农户作物种植制度行为、生产投入行为的影响制约,需通过农户行为调整来进一步提升耕地经济产出价值;农户自身需要、农户家庭自身拥有的资源、以及国家或区域层次上的宏观因素等内外部因子会通过刺激农户行为动机与目标来改变农户行为,间接影响耕地经济产出价值,因此农户行为调整应以影响农户行为动机的内外部因子及其作用机理为指导,针对性地采取综合措施来规范农户行为。

On the basis of calculating the economic output values, with the income capitalization approach, of paddy field and dry field samples in study area, the effect of farmers＇ behaviors on the economic output values of cultivated land was studied by using the methods of correlational analysis and Cobb-Douglas production function. Furthermore, according to the motivation theory, the mechanism that farmers＇ behaviors affect the economic output value of cultivated land was constructed. The results suggest that： there is substantial fluctuation among the economic output values per hectare of paddy field and dry field samples in study area, and the economic output values per hectare of paddy field samples are generally higher than that of dry field samples; the economic output values of paddy field and dry field samples in study area are differently affected by farmers＇ crop production system behavior and production inputs behavior, therefore, in order to further promote the economic output values of farmland, there are some need to adjust the household behaviors ; the internal and external factors ,such as the demand of farmers, the resources of peasant families and national or regional macro-factors etc, will indirectly influence the economic output value of cultivated land by stimulating farmers＇ motivations and objectives to change farmers＇ behaviors. Thus the adjustment of farmers＇ behaviors should take the internal and external factors that affect household behaviors and its action mechanism as the instruction, and pointedly adopt comprehensive measures to standardize the household behaviors.
