If we assume countries as a node, one way to show the trade flow between
two countries is to connect with a straight line. These straight lines also
called as edges. The arrow direction of the edges represents which country
trade is made to. By adding the trade amounts on the
edges, the export amounts of the countries can also be seen easily on the graphs.
If we do the same for all countries, international trade flows become a big and
complex world trade network. In this study, the trade relations of 50 countries
with the highest export level before and during the Covid-19 pandemic were
examined by network analysis method. Gephi 0.9.2 program, which has superior
visualization ability compared to other network software programs, was used in
the visualization of relations, node and network calculations. The most basic
and expected result in the study is that the total export level of the
countries has decreased with the pandemic. Although the export level of the
countries has decreased with the pandemic, it is seen that the People's
Republic of China is on the rise, albeit by a small margin. It is observed from
the graphs that the countries are geographically close to each other have more
trade relations. At this point, it can be said that geographical proximity
plays an important role in trade flows. Regionally, in the trade flows of
countries with each other, the European continent has the most intense
connections between each other and the African continent has the least
connections. Although Germany is the country with the most trade connections,
it is the 3rd country in terms of export level and China is the country with
the highest export amount. In this context, it has been concluded that the
number of connections as well as the level of exports are also effective in the
economic development of countries. Countries with high export levels seem to
have certain trading partners. In this study, it was concluded that despite the
worldwide crises such as the economic contraction of the countries or the
pandemic that may affect all countries, the commercial partnerships did not
change.
