| 中文摘要: |
| 按照不同地区油料油脂的产销特点，将我国七大地理分区划分为余油区、缺油区和基本自给区，在定性分析各区油料油脂产销结构变化的基础上，运用几乎理想需求系统模型对不同区域内大豆油、菜籽油和花生油的消费支出弹性和价格弹性进行测度，以此明确不同区域消费品种之间的替代互补关系。结果表明：余油区整体油料油脂供需结构和量上较为匹配，3种油脂之间存在消费替代关系，且菜籽油和大豆油之间的替代程度较强；缺油区内油料油脂产销之间存在一定程度的结构匹配，但量上存在较大差距，其中菜籽油和花生油之间存在消费替代关系，大豆油与菜籽油、花生油是消费互补关系，但无论替代还是互补程度都较弱；基本自给区有向缺油区发展的态势，区内花生油和菜籽油之间是互补关系，大豆油与这两种食用植物油之间是替代关系。基于以上分析，分别从各区域油料生产发展、区域间调运合作以及消费需求端3方面提出了优化建议。 |
| 英文摘要: |
| According to the production and sales characteristics of oilseeds and oils in different regions, the seven geographic regions of China were divided into oil-remaining area, oil-deficient area and basic self-sufficiency area. Based on the qualitative analysis of the changes in the production and sales structure of oilseeds and oils in each area, the almost rational demand system model was used to measure the consumption expenditure elasticity and price elasticity of soybean oil, rapeseed oil and peanut oil in different regions to clarify the substitution and complementary relationship between consumption varieties in different regions. The results showed that the overall supply and demand structure and quantity of oilseeds and oils in the oil-remaining area were relatively matched, and there was a consumption substitution relationship among the three oils, and the degree of substitution between rapeseed oil and soybean oil was the strongest.There was a certain degree of structural matching in oil-deficient area, but there was a large gap in quantity,in which there was a consumption substitution relationship between rapeseed oil and peanut oil, and there was a consumption complement relationship between soybean oil and rapeseed oil or peanut oil, but the degrees of substitution and complementary were weak. The basic self-sufficient area had a tendency to develop into an oil-deficient area,and peanut oil and rapeseed oil were complementary in the area, and soybean oil and these two types of edible vegetable oil were substituted. Based on the above analysis, optimization suggestions were put forward from the three aspects of regional oilseed production development, inter-regional transportation cooperation and consumer demand side. |
