Abstract: To explain clearly the mechanism of the symbiotic development of stateowned economy and private economy in theory is the need to better adhere to “two unswervingly”.Based on LotkaVolterra model,this paper theoretically proves the symbiosis of stateowned economy and private economy and how the “1+1 >2”effect realizes. Based on the time series data of stateowned and private listed companies from 1992 to 2018, the empirical analysis result using VAR model shows that the development of stateowned economy promotes the expansion of market scale and contributes to the development of private economy; the development of private economy promotes the expansion of market scale and contributes to the development of stateowned economy; the expansion of the market has expanded the development space for the symbiotic development of the stateowned and private economies, and promotes mutual cooperation and winwin results between the two. From the perspective of market scale effect, this paper explains the mechanism of the symbiotic development of stateowned economy and private economy.
