本文通过建立城镇居民水产品消费的双对数需求模型,考察了居民收入水平、水产品自身价格和相关商品价格对水产品需求量的影响。模型结果表明,影响城镇居民水产品消费的因素主要是居民人均收入水平和水产品价格,且前者与水产品人均消费量呈正相关,后者与水产品人均消费量呈负相关。
In this paper, by establishing a double logarithm demand model of consumption of aquatic products for urban residents, this paper examines the impact of residents’ income level, the price of aquatic products and the related commodity prices on the demand for aquatic products. The results of the model show that the main factors influencing the consumption of aquatic products in urban areas are the per capita income of residents and the price of aquatic products. The former is positively correlated with the per capita consumption of aquatic products, while the latter is negatively correlated with the per capita consumption of aquatic products.
