基于当前“一球两制”的社会发展现状,要深入理解与研究马克思的社会发展趋势理论。同时,也要用开阔的眼界来认识此理论在现实中的运用,以宏观历史视野以及辩证的思维方法来正确对待当代资本主义的新变化与社会主义的发展趋势。马克思的社会发展趋势理论在当代具有重要的指导意义。 Based on the current social development status of “one ball, two systems”, we should thoroughly understand and study Marx’s social development trend theory. At the same time, we should also understand the application of this theory in the real world with an open horizon and correctly handle the new changes in contemporary capitalism and the development trend of socialism with macroscopic historical perspectives and dialectical thinking. Marx’s social development trend theory has an important guiding significance in the contemporary era.
