Research on the Influence of Depth and Breadth of Equity Reform on the Performance of State Owned Enterprises Based on Dynamic Panel Data Model

Abstract

In order to explore the necessity of mixed ownership reform of state-owned enterprises and clarify the direction of mixed ownership reform of state-owned enterprises in China, this paper uses dynamic panel data model and bootstrap-DEA method to study the impact of “depth” and “breadth” of equity reform of state-owned enterprises in China on the performance of state-owned enterprise. The results show that there is an inverted U-shaped relationship between performance and the level of equitable reform of state-owned enterprises. When the depth of equity reform is 36.6%, the performance of mixed reform enterprises is the best. There is a positive U-shaped relationship between the breadth of equity reform and the performance of state-owned enterprises. When the breadth of equity reform is 12.47%, the performance of mixed reform enterprises is the worst. At the same time, it is found that the average performance of the sample enterprises shows an obvious downward trend, while the performance variance of the sample enterprises shows an obvious upward trend, and this trend has not changed significantly after China launched a new round of state-owned enterprise reform in 2015. According to the above research findings, this paper believes that the intervention of government forces is conducive to promoting the survival of the fittest of state-owned enterprises and the overall optimal allocation of social resources, but we should pay attention to the adoption of market-oriented means and should not directly interfere with the mixed reform of state-owned enterprises. At the same time, the mixed reform of state-owned enterprises in China is either relatively thorough, giving up the dominance of the largest state-owned shareholder, giving other shareholders a greater say, or not to carry out mixed reform, or symbolic mixed reform, otherwise it may aggravate the internal friction of the mixed reform state-owned enterprises, resulting in worse performance.
