摘要: 国企改革和创新效率的改善对我国国民经济发展具有重要影响。本文以国民经济核算(SNA)框架下的企业研发核算为基础,构建随机前沿模型测量创新效率,运用PSM-DID法研究了国企混改对创新效率的影响。结果表明,总体而言混改没有提升国企的创新效率,但能够提升自然垄断企业的创新效率,这为分类混改思路提供了实证支撑。本文借助断裂带概念进一步研究了混改对创新效率的影响途径,发现混改带来的决策主体即董事会构成的改变导致了企业决策环境和决策行为的变化,混改董事会断裂带对混改对企业创新效率的影响具有有利的调节作用。研究结果为如何借助混改提升企业创新效率提供了有益的决策参考。

Abstract: Reform of state-owned enterprises and improvement of innovation efficiency have an important impact on the development of our national economy. This paper adjusts the R&D accounting of enterprises under the SNA framework to measure the innovation efficiency through the stochastic frontier model, and with PSM-DID, this paper carries out research on how reform of mixed ownership effects the innovation efficiency of stated-owned enterprises. The research based on the total sample shows that mixed ownership reform has no effect of improving innovation efficiency; classified sample reseach indicates that the reform can improve the natural monopoly enterprises, which renders empirical support to the idea of mixed ownership reform by classification. Further research with faultline shows that mixed ownership reform changes the composition of the board of directors, and thus changes the decision-making environment and behavior of enterprises. Faultline of board of directors in mixed ownership reform positively regulates the impact of the reform on state-owned enterprises’ innovation efficiency. It provides a useful decision-making reference on how to improve the innovation efficiency of enterprises by means of mixed ownership reform.
