摘要
基于陕西农村固定观察点农户调查数据,利用联立方程模型对多投入—多产出农户的农作物种植行为、生产要素配置行为及其影响因素进行分析。研究发现:多投入—多产出农户的农作物种植行为比较复杂,不同产品生产存在明显的交互影响,使用联立方程模型方法能够取得较好的估计结果,对当前多样化经营农户种植行为有着良好的解释力与政策寓意;而基于生产函数估计的要素边际替代率估算及其影响因素的联立方程估计,对生产函数所揭示规律的深入分析有着重要推进作用。实证分析结果显示:多投入—多产出农户农作物生产,并未严格地按照直观的"比较优势"原理进行生产要素的优化配置,造成这种现象的原因是多方面的,加快推进传统农业的系统改造成为必须。
Based on the data from a representative household survey in Shaanxi province, this paper analyses the crop planting and factor allocation behavior of agricultural household about the multi-input and multioutput by the way of simultaneous equations model（SEM）. And this paper finds： it is relatively complex that the behavior of crop planting is the multi-input and multi-output, because of the interacting influence among the different outputs. So, it is appropriate to use the simultaneous equations model, and it can find out many explanations and suggestions, which are useful to understand the diversified management of modern agricultural household in China. And the estimation and analysis of marginal substitution rate is helpful to understand the outcome of production function analysis. This paper also finds that the household＇s allocation of production factors doesn＇t according to the principle of comparative advantage, so it is necessary to change the Chinese traditional agriculture systematically.
