In modern society, the process of producing is not only a process of material product to be produced， distributed, exchanged and consumed, but also a process of knowledge products to be produced, distributed, spread and applied. Not only the social relations that are formed among people during the process of material product to be produced, distributed, exchanged and consumed exist, but also the social relations that are formed among people during the process of knowledge products to be produced, spread and applied exist as well. With the development of socialist market－ economy system in our county, the social relations that are formed during the process of producing knowledge product will convert from unpaid, indirect and unprofitable to paid, direct and mutual profitable under planned－ economy system.
