我有个问题啊 就是国家简称是怎么看的啊。。。我分不清哪个国家是哪个啊。。。求帮忙~~~
The 13 repeated lines for countries having two capitals can be easily dropped using for instance the dummy
maincity explained in the next subsection.
3The numeric codes are the United Nations Standard Countries/Area codes used in trade data. Consequently, the
code for Belgium is not 056 but 058, the Belgium-Luxembourg code.
4Countries and capital names in French follow “Pays et capitales du Monde. Pays indépendants au 1.01.2001” of
the Institut Géographique National. English names follow “The World Factbook” of the CIA.
