Analysis on the Comparison of the Research Object of Economics

By comparing the research object of Marxism political economics and that of western economics,in this composition I draw three conclusions:First,the research object of economics is a system,which can be divided into abstract-level,middle-level and concrete-level objects;Second,the low-level objects are changing;Third,the low-level objects are nationalized.On this basis,the author suggests that if we wish to establish “Chinese Economics” we should establish a dynamical and nationalized system of research object of economics.
