Abstract:Efficiency can be divided into value-form efficiency and non-value-form efficiency. To study the efficiency of civil-military integration, we must start from the non-value perspective or from the value perspective when the prices of inputs and outputs are relatively constant. This paper studies the basic concepts and causes of the efficiency risk of civil-military integration in defense science and technology industry, and analyses the relationship and mechanism of the efficiency risk of civil-military integration from four aspects: competition and monopoly, production scale, division of labor and diversification. In order to avoid the risk of resource efficiency of civil-military integration, it is necessary to follow the development law of civil-military integration, improve the integration management mechanism and purify the environment of civil-military market.
