Abstract: The existence of Marx economic philosophy system is a fact that cannot be denied.It exists in four forms: critique on the foundation of bourgeoisie economic philosophy,philosophy in the domain of political economy,and philosophy in the proposition of political economy and in the theory of political economy.Young Engels is the initiator and guide in the forming history of Marx economic philosophy system.During the process,1859 is the starting point when Engels wrote the review on Critique on Political Economy Ⅰ.Afterwards Engels made changes to Marxist theory and developed his own system of philosophy,entitled dialectic materialism,although he meant to safeguard,interpret and propagate Marx economic philosophy.After Engels passed away,dialectic materialism becomes orthodox Marxist philosophy,which evolved into dialectic materialism and historical materialism in textbooks.As a result of lack of theoretical and logic room for its existence,the system of economic philosophy in Marx economic philosophy has been ignored and disappeared from the orthodox Marxist philosophy.
