基于熵值法的主要坚果贸易国综合竞争力评价OA
Comprehensive competitiveness evaluation of major nut trading countries based on entropy method
基于UN Comtrade数据库2014-2023年世界坚果贸易数据,描述了世界坚果贸易格局,并分析了主要坚果国际市场占有率(IMS)、显示性比较优势指数(RCA)、国际贸易竞争力指数(TC)和出口价格优势指数(EPI)等竞争力评价指标,在此基础上,运用熵值法进一步测算分析了综合竞争力.结果表明:近十年来中国对世界坚果进口贸易额增长的贡献率远大于出 口额,坚果贸易逆差持续扩大;中国在坚果贸易中的竞争优势较弱,但国际市场占有率、显示性比较优势指数和综合竞争力指数均呈持续上升趋势.
Based on world nut trade data from 2014 to 2023 from the UN Comtrade database,this paper described the global nut trade pattern and analyzed competitiveness evaluation indicators such as International Market Share index(IMS),Revealed Comparative Advantage index(RCA),Advantages in Trade Competitiveness index(TC),and Export Price Advantage index(EPI)of major nut trading countries.On this basis,the entropy method was further used to calculate and analyze the comprehensive competitiveness.The results showed that in the past decade,China's contribution to the growth of world nut import trade had far exceeded its export volume,and the nut trade deficit had continued to widen.China had a relatively weak competitive advantage in nut trade,but its IMS index,RCA index and comprehensive competitiveness index were all showing a continuous upward trend.
