摘要

从区域差异视角出发,研究经济政策不确定性对我国农业上市公司投资效率的影响.研究发现,经济政策不确定性升高时农业上市公司投资效率降低,并且对于中西部地区农业上市公司这一效应更为明显.提出中西部地区农业上市公司要充分考虑市场中的经济因素,把握良好的投资机会并做出最优的投资决策,公司管理层应该正确判断投资项目未来前景,从而提高公司投资效率的建议.
        This paper studies the impact of economic policy uncertainty on the investment efficiency of China's agricultural listed companies from the perspective of regional differences. The study found that the investment efficiency of agricultural listed companies decreased when economic policy uncertainty increased, and the effect was more obvious for agricultural listed companies in the central and western regions. It is proposed that agricultural listed companies in the central and western regions should fully consider the economic factors in the market, grasp the good investment opportunities and make the best investment decisions. The management of the company should correctly judge the future prospects of the investment projects and thus improve the investment efficiency of the company.
