Quantifying the Robustness of Countries’ Competitiveness by Network-Based Methods

الملخص EN

In economic researches, much effort was devoted to the problem of how to increase the economics of countries.

However, the development of a country may fluctuate a lot due to international and domestic problems.

Thus, we should also evaluate the robustness of countries against unexpected economic recessions.

In this paper, we use perturbation to quantify the robustness of countries using two renowned algorithms: method of reflections (MR) and fitness-complexity method (FCM).

The robustness characterizes the stability of countries’ competitiveness against economic recessions.

The experiments in the international trade networks show that FCM could characterize the robustness better than MR.

High fitness countries of FCM have strong robustness against economic crises, which enlarges the application fields of FCM.

Additionally, we simulate the trade conflict between USA and China.

The simulation results show that China suffers much in the trade conflict, while USA loses very little and has strong robustness in this conflict.
