摘要
本文利用2002-2011年江苏地区的面板数据建立了面板门槛模型,从农民纯收入视角对农业物质要素投入产出弹性进行了测算,结论如下:农业机械总动力、有效灌溉面积、农作物播种面积、农业用电量等物质要素的投入产出弹性存在显著的农民纯收入变动"门槛效应":当农民纯收入高于10600元时农业机械总动力、有效灌溉面积、农业用电量的产出弹性会增加,当农民纯收入高于11800元时,农作物播种面积的产出弹性会增加;目前苏南5个地区农民纯收入已超过118000元的门槛值,但苏北大部分地区农民纯收入仍处于10600元的门槛值以下,制约了农业物质要素投入产出弹性的进一步提高。
This paper sets up the panel threshold model by using the panel data in various areas of Jiangsu from 2002 to 2011. It calculates the input-output elasticity of agricultural materials from the perspective of farmers' net income. Conclusions are drawn as follows: the input-output elasticity of material elements such as the total power of agricultural machinery,the effective irrigation area,the sown areas of farm crops and agricultural use of electricity has a significant ' threshold effect' on the farmers' net income changes. When the farmers' net income is more than 10600 yuan,the output elasticity brought by the total power of agricultural machinery,the effective irrigation area and the agricultural use of electricity will increase; when the farmers' net income is more than 11800 yuan,the output elasticity of the sown area of the crops will increase. At present,there are 5 areas where farmers' net income exceeds 118000 yuan threshold in the South of Jiangsu Province. But the farmers' net income in the northern Jiangsu is still below the threshold,which restricts the further rise of input-output elasticity of agricultural materials
