| Abstract: |
| 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. |
