摘要
中国是世界上最大的水果进口国之一,近年来贸易额逐渐上升。需求多样化推动了水果需求多样化的研究。参考Hummels&Klenow(2005)的三元边际模型,研究2000—2021年中国水果进口的广度增长、数量增长和价格增长。再使用多元回归模型分析影响三元边际三个变量的影响因素。研究结果表明,中国进口水果广度很大且稳定,价格指数逐年增长,数量指数波动较大。中国需要促进合作运输和国际物流的发展,促进自由贸易协定的签订,以促进贸易便利化。
China is one of the world's largest importers of fruit,and the trade volume has gradually increased in recent years.The diversification of people's demand promotes the research on the diversification of fruit demand.Based on the three-way marginal model of Hummels&Klenow(2005),this paper studies the breadth growth,quantity growth and price growth of China's fruit imports from 2000 to 2021.Then the multivariate regression model is used to analyze the influencing factors of the three variables.The results show that the breadth of China's imported fruits is large and stable,the price index increases year by year,and the quantity index fluctuates greatly.China needs to promote the development of cooperatives and international logistics,and promote the signing of free trade agreements to promote trade facilitation.
