国有经济与民营经济共生发展的市场规模效应研究*

从理论上阐释清楚国有经济与民营经济共生发展的机理,是更好坚持“两个毫不动摇”的需要。本文基于Lotka Volterra模型,从理论上证明了国有经济与民营经济共生发展,实现了“1+1>2”的效应。本文利用1992—2018年国有上市公司与民营上市公司时间序列数据,使用VAR模型的实证分析结果显示：国有经济发展,推动市场规模扩大,有助于民营经济发展;民营经济发展,推动市场规模扩大,有助于国有经济发展;市场规模扩大为国有经济与民营经济共生发展拓展了发展空间,促进二者相互合作、互利共赢。本研究成果从市场规模效应视角,解释了国有经济与民营经济共生发展的机理。

STUDY ON THE MARKET SCALE EFFECT OF THE SYMBIOTIC DEVELOPMENT OF STATE-OWNED ECONOMY AND PRIVATE ECONOMY

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.
