This study aims to analyze the characteristics and changes of the network through social network analysis based on the field guidance attendant under the Kim Jong-un regime's winning coalition. And we would like to apply the results to the electorate theory to examine Kim Jong-un's control of the North Korea’s winning coalition. The analysis found evidence that the Kim Jong-un regime's winning coalition was shrinking and reshaping, and that it was not grouped independently. If this is applied to the electorate theory, it can be said that Kim Jong-un has control over the winning coalition. This can be interpreted as a basis for the stability of the Kim Jong-un regime.
