摘要:

茭白作为一种小宗鲜食型高端水生蔬菜,研究其价格波动特征对把握茭白市场价格规律、促进农民增收具有重要作用。本文运用自回归条件异方差模型(ARCH类模型)对2014—2023年全国茭白价格波动特征进行分析。结果表明,茭白价格具有显著的波动集簇性。茭白作为小宗农产品具有“高风险高收益、低风险低收益”特征。我国茭白价格信息存在“杠杆效应”,冲击的影响是非对称性的。据此提出提高机械化水平、降低生产成本,强化品牌建设、提升产品竞争力,延长上市周期、提高抗风险能力等措施,以期促进茭白产业健康发展。

Abstract:

As a kind of premium aquatic vegetable, the study on price fluctuation of Zizania latifolia is of great importance for grasping the market price rule and increasing farmers' income. In this paper, the ARCH model was used to analyze the price fluctuation characteristics of Zizania latifolia in China from 2014 to 2023. The results showed that the price of Zizania latifolia had significant fluctuation and clustering. As a small farm product, Zizania latifolia had the characteristics of “high risk and high return, low risk and low return”. There was a leverage effect in the price information of Zizania latifolia in China, and the effect was asymmetrical. According to this, it is proposed to improve the mechanization level and reduce the production cost, strengthen brand building, enhance product competitiveness, prolong the market cycle and improve the ability of anti-risk, in order to promote the healthy development of Zizania latifolia industry.

Key words: farmer's income, price fluctuation of Zizania latifolia, ARCH model
