Abstract: There are a lot of disputes on 'stepping over capitalist Kafuting canyon'. It is very difficult to reach a unanimous viewpoint. Getting to the root of matter, its most ultimate reason lies in the traditional metaphysical thoughtway of understanding market economy, socialism, and capitalism. Seeing socialist market economy with the all-around and dialectical sight is the ultimate means to dissolve the dispute. This is a process of understanding, and also is a process of practice.
