“Two combinations” is the scientific method for CPC to constantly promote theoretical innovation. How to correctly understand and grasp the scientific method of theoretical innovation? This paper holds that the theoretical innovation of “two combinations” needs to be viewed from the philosophical significance of “combinations”. The “first combination” broadens the practical dimension of Marxist worldview and methodology, while the “second combination” enriches its theoretical dimensions. Through the historical and practical analysis, the worldview presented by the “two combinations”, in theoretical innovation reflects the views on practice, nationality and culture based on facts and rooted in China. Besides, it is also reflected methodologically in the unity of the “six musts” .
