The book opens a journey spanning 14 years, from the day of the country's reunification to the early steps of the Doi Moi process, when Vietnam's economy operated in a centralized planning model, facing countless difficulties in production, distribution, management mechanisms, etc in a volatile international context. This is the time when Vietnam's economic thinking has changed the most strongly, quietly, and also the most complicated. The book is especially valuable in recreating the "nodes" of thinking: the price-wage-money mechanism in 1985; contracting products in agriculture; accounting in industry; circulation and distribution reform; opening the door to foreign trade; local test models; the role of economic experts and research centers in this period. Dang Phong presents those changes in a clear, fair voice, which is both historic and shows the flow of thought of an economy that is seeking to overcome the crisis on its own.
