Abstract: The reformers of the landlord class endeavored to achieve self-prosperity with the foreign developed methods,which retarded the progress of semi-colonizing china.In military,they manufactured the war ship and cannon and organized and drilled the navy. As a result, the strength resisting the enemy was fortified and the swift and the fierce attack of the western gun and cannon was routed.In economy,they engaged in the western-style industry and commerce,finishing the monopoly of the foreign capital and weakening the economic invasion of the big powers.Their efforts in economy stimulated the birth and development of Chinese capitalism.Specifically,they introduced the big-scale production by engine to break the closed system of China's natural economy;thanks to their originating western-style enterprise,Chinese capitalism came into being and the bourgeoisie revolution acquired its material foundation.
