摘　　要：选取沪、深两市A股制造业上市公司2002-2015年的数据,采用双重差分模型检验了国有企业民营化改革对企业创新的影响。实证检验结果表明:国企民营化改革与企业创新呈现显著的负相关关系,即相较于始终保持国有性质的企业,国有企业民营化改革削弱了企业的创新能力。立足于国企民营化改革,从管理学视角和微观企业层面考察了国有企业民营化改革的经济后果,为我国正在实行的国有体制改革提供了一定的经验证据。This paper selects the data of A-share companies in manufacturing industry listed inShanghai and Shenzhen stock markets during the period from 2002 to 2015 to conduct a test on the impact of the privatization of state-owned enterprises on the enterprise innovation with the differ- ence-in-differences model. The empirical results show that there is a significant negative correlation between the privatization of the state-owned enterprises and enterprise innovation, namely, compared with enterprises always keeping the state-owned nature, the privatizafion reform of the state-owned en- terprises has weakened the innovative strength of enterprises. Based on the privatization reform of state-owned enterprises, this paper investigates the economic results of the privatization reform of state-owned enterprises from the management perspective and on the micro enterprise level, which can provide some empirical evidences for the state-owned system reform being carried out in China.
