摘要
粮食国际市场竞争力下降已成为我国粮食安全问题的重要诱因。通过构建基于生产成本的比较优势指标分析我国稻谷、小麦和玉米三大粮食产品市场竞争力,剖析生产成本及其结构变化趋势,通过计量经济模型分析与因素分解,测算收储政策和劳动力工资上升对我国粮食市场竞争力变化的影响程度。研究表明,相较于美国,我国主要粮食产品均处于比较劣势。收储政策和劳动力工资上升对我国粮食产品国内生产者价格和竞争力下降均影响显著,但两者对不同粮食产品影响存在差异。收储政策对小麦、粳稻和籼稻影响程度大于劳动力工资上升,劳动力工资上升对玉米影响程度大于收储政策。研究就收储政策实施和劳动力工资上升应对措施提出建议。
The international market competitiveness of grain has become an important cause of grain security in China.By constructing the comparative advantage index based on production cost,the market competitiveness of rice,wheat and corn in China were analyzed,the production cost and its structural change trend were analyzed and the econometric model was used to analyze and decompose the factors.The influence and extent of the policy of collecting and reserving and the increase of labor wage on the change of grain market competitiveness in China were calculated.Research showed that,compared with the United States,China main grain products were at a comparative disadvantage.The policy of collecting and reserving and the increase of labor wage had significant effects on the price and competitiveness of domestic producers of grain products in China,but there were differences among them on different grain products.The effect of storage policy on wheat,japonica rice and indica rice was greater than that on labor wage,and the effect of labor wage increase on maize was greater than that on maize.Some suggestions on how to perfect the policy of collecting and storing and how to improve the wage of labor force were put forward.
