Abstract
The sufficient and necessary condition for the two-sector expanded reproduction is also the condition for the existence of solution of Marx’s expanded reproduction scheme.By now the condition has not been defined strictly because a general method of solution to Marx’s expanded reproduction scheme has not been presented scrupulously.This paper set a gen-eral method of solution to the problem of the two-sector expanded reproduction with a necessary condition which has been ob-tained in some research.Therefore,this necessary condition was proved to be the sufficient and necessary condition for the re-production.Then,by use of a method of variable substitution,the paper gave another method of solution to the expanded re-production by taking direct solutions to the rates of surplus valuable accumulation of two sectors.Finally,two examples from Marx’s “Das kapital”were drawn upon to verify two methods of solution to the problem of the expanded reproduction in a cal-culative way.关键词
