【摘要】：Hotelling模型提出存在转换成本时,即使产品同质也会发生"价格离散"现象。本文从转换成本视角,构建了企业和农户间的供求均衡模型,发现成交价格是买方转换成本的增函数,是卖方转换成本的减函数;以1312个企业与水稻种植户交易数据为样本,运用二元Logistic回归分析,对模型假说进行了实证检验,结果表明,企业转换成本对成交价格有显著正向影响,农户转换成本较低是企业"溢价"收购的前提;成交价格主导方在于企业,规模较大的、经营特色品种的企业转换成本较高,"溢价"收购可能性较大,对农户的增收效应较为明显。这些结论支持了Hoteling模型关于"价格离散"的理论推断,有利于政府制定有效的农业产业化政策,实现精准扶持,真正促进农民增收。
[Abstract]:Hotelling model puts forward that even if the product is homogeneous, the "price dispersion" will occur in the existence of conversion cost. In this paper, the equilibrium model of supply and demand between enterprises and farmers is constructed from the perspective of conversion cost. It is found that the transaction price is the increasing function of the buyer's conversion cost and the decreasing function of the seller's conversion cost. Taking the transaction data of 1 312 enterprises and rice growers as a sample and using binary Logistic regression analysis, this paper empirically tests the hypothesis of the model. The results show that the transaction price is significantly positively affected by the cost of enterprise transformation. The low conversion cost of farmers is the premise of "premium" acquisition; The leading party of the transaction price lies in the enterprise, which has the larger scale and the higher cost of the enterprise with special operating characteristics, the higher possibility of "premium" acquisition, and the more obvious effect of the increase in income to the peasant household. These conclusions support the theoretical inference of "price dispersion" in Hoteling model, which is helpful for the government to formulate effective agricultural industrialization policy, to achieve accurate support, and to promote farmers' income.
