摘要
本文使用1998-2013年中国工业企业数据库,采用国际前沿方法识别出僵尸企业,然后比较了国企控股、国企参股以及转制民企这三种混合所有制改革策略治疗僵尸国企的效果。实证结果表明:相对于纯国企,混合所有制改革对僵尸国企具有显著的治疗效果;在多种混合所有制改革策略中,转制民企优于国企参股,国企参股优于国企控股,这形成了一种"国企混改类啄序"现象;然而,上述"啄序"现象并非对所有国企都适用,对于那些所处行业垄断程度高、企业政治级别高的国企,单纯民营化导向的混改对僵尸企业治愈的效果较差;最后,混合所有制改革治疗僵尸国企的主要渠道,是降低了国企的期间费用(主要是管理费用)。本文的结果为处置僵尸企业和渐进式改革提供了重要的理论依据。
Supply-side structural reform has become the main direction of China’s current economic reform,and its primary task is de-capacity. The key to de-capacity is the elimination of zombie firms. Because state-owned enterprises( SOEs) usually incur greater resource misallocation,the proportion of zombie firms is higher among SOEs. Mixed ownership is the main focus of Chinese SOE reform,as studies have found that the introduction of non-state capital improves firm performance through better corporate governance mechanisms and the mitigation of resource misallocation.The question that concerns us here is whether mixed ownership can cure state-owned zombie firms,and if so,which type of mixed ownership is most conducive. This paper deepens the theoretical research on both zombie enterprises and mixed ownership reform for state-owned enterprises,and also improves the theory of resource misallocation from the perspective of mixed ownership,potentially solving the problems of long-term inefficiency among SOEs and the burgeoning of zombie firms in China.We first apply the international cutting-edge method to identify zombie enterprises. To be recognized as a zombie firm in the current year a company must meet the following four conditions:( 1) the loan interest rate is lower than the normal market minimum interest rate;( 2) earnings before interest and tax are lower than the payable interest in the current year;( 3) the liability-asset ratio of the previous year exceeds 50% and the firm continues to borrow in the current year;and( 4) the first three criteria have been met for the past two consecutive years.Next,we divide the firms with mixed ownership into three categories according to the proportion of state-owned shares: state-control firms,state-holding firms( firms with state capital but not controlled by the state),and privatized firms( firms with no state capital,a special type of mixed ownership). We then explore whether mixed ownership reform can help to cure zombie firms and which type of mixed ownership reform works best.Using a panel dataset of Chinese industrial enterprises from 1998 to 2013,we obtain some interesting results. First,mixed ownership reform is found to have a significant impact in improving zombie SOEs. Second,the improvement is greater for privatized firms than for state-holding firms,which in turn fare better than state-control firms,forming a 'pecking order'for mixed ownership reform. Third,the higher the monopoly and administrative level of SOEs,the weaker the effect of mixed ownership reform in curing zombie SOEs. Finally,we find that the main channel through which mixed ownership reform cures zombie firms is a reduction in the SOE’s periodic expenses,such as management expenses.Due to the limitations of the data,this research may suffer from endogenous problems such as omitted variables through overlooking factors that affect the improvement of zombie firms and the mixed ownership reform strategy. This paper examines possible endogeneity issues. This paper makes three contributions to the literature.First,it enriches the research on zombie companies. Zombie firms can lead to resource misallocation and reduce economic efficiency,and thus are an important issue for both policymakers and scholars. Whereas the existing literature examines the causes or influences of zombie firms,this paper analyzes several strategies for treating zombie enterprises,points the way for their elimination,and provides a theoretical basis for further research on how to deal with zombie enterprises. Second,this paper develops the literature on SOE reform by indicating that mixed ownership can improve the efficiency of SOEs and,to an extent,cure zombie SOEs. Moreover,using a variety of mixed ownership types,this paper specifically reveals a'pecking order'in the reform of state-owned enterprises. Third,this paper extends the resource misallocation theory from the perspective of mixed ownership reform,finding that mixed ownership reform can cure zombie state-owned enterprises to an extent,thus reducing resource misallocation. Following this line of thought,we can further expand the research by exploring the actual contribution and channels of mixed ownership reform in improving resource misallocation.
