摘要
研究目的:剖析不同农地经营规模下农户种植行为选择,分析经营规模与种植结构的关系。研究方法:门槛效应模型。研究结果:经营规模扩大对种植结构的影响是非线性的,其过程会受到家庭劳动力禀赋的制约,即存在门槛效应,当家庭劳均经营规模小于门槛规模时,经营规模扩大会促进农户种植经济作物,导致种植结构变化呈“去粮化”,反之当家庭劳均经营规模超过门槛规模时,经营规模扩大会促进种植结构“趋粮化”。研究结论:规模经营不必然引发非粮化生产,因而可以进一步发展农业适度规模经营,通过完善农业社会化服务缓解农业生产的家庭劳动力约束,并以多种方式提高种粮收益以稳定粮食生产,保障国家粮食安全。
The purposes of this paper are to analyze the planting behavior choice of farmers under different scales and to answer the relationship between operation scale and planting structure.The research method is threshold effect model.The results show that the effect of scale expansion on planting structure is nonlinear,this process will be restricted by domestic labor endowment,that is,there is a threshold effect.When the average scale of family labor operating in agriculture is less than the threshold scale,the expansion of the operation scale will promote the farmers to grow cash crops,resulting in the planting structure De-Grained.On the contrary,when the average scale of family labor operating in agriculture is more than the threshold scale,the expansion of operation scale will promote the planting structure Grain-Oriented.In conclusion,scale operation does not necessarily lead to non-grain production,so moderate scale operation in agriculture can be further developed,family labor constraint of agricultural production can be alleviated by improving agricultural socialized services,and the income of grain growing can be upgraded in various ways to stabilize grain production and guarantee national food security.
