双重目标下的陕西省稻农农地转入最优价格探讨——基于农地产出和生产利润最大化的视角

Discussion on Optimal Price of Farmland Transfer for Rice Farmers in Shaanxi Province under Dual Objectives Based on Perspective of Farmland Output and Production Profit Maximization

基于陕西省汉中、安康两地转入农地的稻农问卷调查数据,采用Translog生产函数构建了投入产出模型和生产利润模型,从产出和利润两个维度对稻农转入农地的价格效应进行了实证研究,分析了农地转入价格对稻农的产出水平和生产利润的影响,确定了农地产出最大化与生产利润最大化双重目标下的稻农农地转入最优价格。结果表明:(1)以农地转入价格0~1500元/hm^(2)为参照,稻农农地转入价格在7500~10500元/hm^(2)时,其产出水平显著上升。(2)稻农农地转入价格在7500~10500元/hm^(2)时,其利润水平显著上升;稻农农地转入价格在10500~13500元/hm^(2)时,其利润水平显著下降。(3)综合权衡产出最大化与利润最大化双重目标,稻农转入农地的最优价格介于7500~10500元/hm^(2)之间。综上,在推进中国农地流转的过程中,应从农民经济效益、国家粮食安全、农村社会稳定和农地流转市场化等多方面考量,把握好农地流转价格的选择标准,以期提高农地流转效率、维护农民权益以及保障我国粮食安全。

Based on the questionnaire survey data of rice farmers transferring farmland in Shaanxi Province,an input-output model and a production profit model were constructed by the Translog production function.This article conducted empirical research on the price effect of rice farmers transferring farmland from two dimensions:output and profit,analyze the effect of land transfer price on the yield level and profit of rice farmers,and determined the optimal price for rice farmers’transferring farmland under the dual goals of maximizing agricultural land output and production profit.The results show that:(1)The farmland transaction price of 0~1500 yuan/hm^(2)is taken as the reference item,and the output level of rice farmers significantly increases when the farmland transaction price is between 7500~10500 yuan/hm^(2).(2)When the farmland transaction price ranges from 7500~10500 yuan/hm^(2),their profit level shows a significant increase.When the farmland transaction price ranges from 10500~13500 yuan/hm^(2),their profit level begins to show a significant decline.(3)Considering the dual goals of maximizing output and maximizing profits,the optimal price for rice farmers to transfer is between 7500~10500 yuan/hm^(2).In conclusion,in the process of promoting the transfer of farmland in China,we should grasp the selection criteria of agricultural land transfer price from the perspective of farmers’economic benefits,national food security,rural social stability and marketization of agricultural land transfer,so as to improve the efficiency of agricultural land transfer,safeguard farmers’rights and interests and guarantee China’s food security.
