中国城乡居民水产品消费量与收入差距关系研究

On the relationship between aquatic products consumption and income gap of urban and rural households in China

随着城乡居民收入水平不断提高,水产品消费数量和质量问题受到越来越多的关注。借助1981~2015年城乡居民水产品消费量指标数据,分析了其长期变化趋势特征,还探讨了城乡居民收入差距与水产品消费量差距之间的长期均衡关系。结果显示:全国居民人均水产品消费量呈现缓慢的增长趋势,在肉类、水产品和禽类消费量总和的比重呈现明显的上升趋势;城镇居民人均水产品消费量与全国平均水平之间的差距逐渐在缩小,2015年,相差额度下降至3.5kg;农村居民人均水产品消费量在增长的同时,与全国平均水平的差距却在逐步扩大;城乡居民收入差距与水产品消费量差距之间存在长期均衡关系。

With the increase income level of urban and rural residents',the quantity and quality of aquatic products are becoming more and more concerned. Based on the data of urban and rural households' consumption of aquatic products from 1981 to 2015,the paper analyzed the characteristics of long-term change trend,and discussed the long-term equilibrium relationship between income gap between urban and rural households and aquatic products consumption. The results show that the " per capita consumption of aquatic products " indicator has a slow growth trend,and the proportion of meat,aquatic products and poultry consumption reveals a significant upward trend; the gap between the urban per capita consumption of aquatic products and the national average is gradually narrowing,the gap dropped to 3. 5 kg in 2015. Per capita consumption of aquatic products in rural residents showed a trend of growing,meanwhile,the gap with the national average is gradually expanding. There is a long-term equilibrium relationship between the income gap and the consumption gap of aquatic products in urban and rural households.
