摘要
在协整检验基础上,分析了小麦价格、单位面积成本与种植面积的长期关系。结果表明前期单位面积成本和前期价格与小麦种植面积间存在长期均衡关系,小麦种植面积受前期价格及前期成本的影响,且前期价格对小麦种植面积的影响更大。最后采用脉冲分析及方差分解来分析小麦价格及单位面积成本对种植面积的影响。
On the basis of co-integration test,this paper anylyzes the long-run equilibrium relation among wheat planting acreage,wheat price and cost per acre.The results suggest that this long-run relation does exist,and the price and cost of wheat have a significant influence on the planting acreage in the long ran,but the direction of the influence is opposite.At the end of the paper,impulse analysis and variance analysis are done to illustrate the influence of price and per acre cost to the planting acreage.
