农村劳动力流动影响农产品价格的实证研究——基于VEC模型的方法

在阐述国内外学者研究情况的基础上,依据19902007年农村劳动力流动和农产品价格数据,利用VEC模型分析了农村劳动力流动和农产品价格的动态均衡关系,采用Chow′s断点检验测算了农村劳动力流动影响农产品价格的阶段性特征。结果表明,农村劳动力流动量和农产品价格之间存在长期稳定的关系;农村劳动力流动正以一种内生的力量影响着农业生产,从而影响着农产品价格的变化;农村劳动力流动对农产品价格的影响力度呈由弱到强,又逐渐减弱的态势,峰值在1998年达到最高;随着我国市场化进程和农村社会经济的发展,农村劳动力流动影响着农产品价格,而且这种影响具有阶段的特征。为了实现农村劳动力流动和农产品价格的双重稳定,提出了相应的对策建议：一是大力发展职业教育,加大对农业生产的支持力度;二是制定积极的就业措施。

Empirical Study on the Impact of Rural Labor Force Flow on the Price of Agricultural Products

Based on the research introduction of domestic and foreign scholars,dynamic equilibrium between the rural labor force flow and the price of agricultural product is analyzed by VEC model,according to the data of the rural labor force flow and the price of agricultural products in the years 1990-2007.Chow's breakpoint test is used to measure the stage characteristics of the impact of rural labor force flow on the price of agricultural product.Result shows that there is a long-term and stationary relationship between the flow quantity of rural labor force and the price of agricultural product.Rural labor force flow,as an exogenous force,affects the agricultural production,and further influences the price fluctuation of agricultural products.Impact of rural labor force flow on the price of agricultural product is from weak to strong,then grows gradually weaker,and reaches its peak value at the year 1998.With the development of rural society and economy and the market process,rural labor force flow endogenously affects the price of agricultural product,which has periodic characteristics.In order to achieve a dual stabilization of the rural labor force flow and the price of agricultural products,the following countermeasures are put forward: vigorously developing vocational education,increasing the support for agricultural production,and making active employment measures.
