摘要
对近年蔬菜价格时间序列数据进行季节调整和H-P滤波分解,发现蔬菜价格不规则因子序列在各年都有较大幅度的振动,季节因子序列具有明显的"V"字态势,Trend趋势线呈直线上升,Cycle循环波动曲线有明显的周期性.建议从健全蔬菜产业市场机制,完善蔬菜市场体系建设,促进蔬菜价格的理性回归,大力实施全国蔬菜产业发展规划等几方面促进蔬菜产业健康发展,合理调控蔬菜价格.
The seasonal adjustment and wave filtering dissolution with time series data of vegetable price have been carried out in this paper. And it has been found that the irregular factor series of vegetable vibrate significantly each year, the seasonal factor series have an obvious ＂V＂ posture, the Trend Line climbs straight up, and the Cycle fluctuation Curve has a distinct periodicity. Some measures should be focused on in order to reasonably regulate and control vegetable price, such as perfecting the market mechanism of vegetable industry, improving the construction of vegetable market system, promoting the rational coming-back of vegetable price, and carrying out the national development plan for vegetable industry.
