This study is to explain the evolution process of North Korea's marketization and to understand the impact of marketization on the change of people's awareness and the improvement of unification capacity. Through the process of marketization in North Korea, the capitalist market economy system is deeply penetrating into North Korean awareness. The marketization made North Koreans aware of private property rights and prefer the market economy system. External information and the Korean wave(Hallyu) brought in through the market made North Koreans think well of South Korean Society and raised expectations for unification. Such changes in the awareness of North Koreans have narrowed the gap between North and South Koreans, and increased the unification capacity of North Koreans. From the perspective of the market economy system, it is expected that the marketization of North Korea and the change of the people's awareness will contribute positively to reduce the cost of unification and the period of unification adaptation between the two Koreas.
