Abstract: One of the most splendid parts of “On Capital” is its analysis and foresight of the stock system.Due to the demand of the development of productive forces,enterprises are making gradual progress to stock system,and then a separation of the property ownership from the possession right of the enterprises (a legal power of management) is shaping up,which,in Marx's opinion,is an objective trend.“The separation of the two rights” is sure to lead to the sociaciztion of the possession and management of the business property.It is easily seen that,Marx once had an indea of realizing the socialism by carrying out stock system,but “the idea of anti-revisionism” has fainted the theory of stock system of Marx science for a long time,and resulted in nearly ten-decades' complications in socialist economy.“The Resolution” of Third plenary session of the 16th Central Committee carries forward directly and develops the stock system theory of Marx Science.This is an important break-through of the theory of the socialist public ownership,i,e.,making the stock system a main form of socialist public ownership.We may call this “New public ownership” “stock system socialism”.In fact,“it is rebuilding individual ownership”(a quotation from Marx),creating economy and the premise of subject for the communism developing in an all round way including personal freedom.

Key words: Marx, stock system, new public ownership, socialism
