The main purpose of this study is to examine the progress of North Korea's corporate reform, its achievements, limitations, and economic effects on economic growth using general equilibrium model. As a result of the analysis, it was analyzed that if North Korea reduces the proportion of autonomous methods using the market in business management, real GDP decreases and investment decreases, which adversely affects the overall economy. In addition, this decrease in production has been shown to significantly increase the market price. In other words, as the proportion of autonomous business management using the market increases, real GDP, consumption, and investment all increase, which has a positive impact on the overall economy. Has been shown to affect. In addition, it was analyzed that the trade balance increased due to the increase in exports due to the expansion of the scope of autonomous foreign trade by companies. The results of this study empirically show how the practical limitations of the Kim Jong-un regime's only partial reforms in the governance structure and production system, excluding corporate ownership structure reform, appear in the indicators promoting economic growth. This raises the need to pursue higher-level reform, such as further increasing the proportion of autonomous business management methods in North Korea's corporate reform. In addition, the results of this study show that if North Korea pursues such desirable corporate reform, the environment for direct foreign trade of North Korean companies and joint ventures and joint ventures with foreign companies will be further expanded. This implies that it will be a major driver in realizing our North Korean policy goals, which are to be fixed and realize the new economic concept on the Korean Peninsula.
