摘要
当前我国正处于经济增速换挡、经济政策频繁波动的不确定时期,微观企业如何通过有效的营运资本管理,对冲经济政策波动的不利影响,是其面临的重要难题。笔者基于经济政策不确定性视角,实证分析了上市公司营运资本管理对企业价值的影响。研究发现:营运资本管理对企业价值存在非对称性影响,对于持有正向超额营运资本的公司,提高营运资本管理效率,适当降低超额营运资本能够提升公司价值;资本投资是营运资本管理价值效应的作用途径,即营运资本管理通过释放流动性保证资本投资提高了公司价值;营运资本管理的价值效应和对资本投资的保障作用在经济政策不确定性高时更显著,说明有效的营运资本管理可缓解政策不确定对投资的不利冲击,进而提升企业价值。
In uncertain times of the slowdown in economic growth and economic policy fluctuations,how to mitigate the adverse influence of economic policy uncertainty through effective working capital management is the challenge faced by many firms. This paper empirically investigates the effect of working capital management on firm value from the perspective of economic policy uncertainty. We find that,( 1) holding excess working capital may have asymmetrical influence on firm value.( 2) holding positive excess working capital may enhance firm value by reducing working capital to foster capital investment and then enhance stock return.( 3) When economic policy is more uncertain,the effect of excess working capital on firm value becomes more obvious,indicating that the reducing of positive excess working capital may provide more financial slack for firms to withstand the negative shock by economic policy uncertainty.
