A study on the efficiency of financial services to the real economy:Based on the DEA-Malmquist model--A case study of Jiangsu Province

文章基于江苏省三大区域10年的融资、增加值等数据,运用DEA-Malmquist模型对江苏金融服务实体经济的效率进行测算,结果发现金融服务实体经济存在区域间差异,金融的“杠杆率”过高或过低都会对实体经济的发展不利。同时,采用三大区域面板数据对金融支持实体经济的影响因素进行检验后的结果表明,直接融资对提高金融支持实体经济的效率有显著性作用。

Based on the 10-year data of financing and added value in three major regions of Jiangsu Province,this paper uses DEA-Malmquist model to measure the efficiency of Jiangsu financial service entity economy.The study finds that there are regional differences in financial services for entity economy,and that too high or too low financial a"leverage ratio"will be detrimental to the development of entity economy.At the same time,the panel data of three regions are used to test the influencing factors of financial support for entity economy.The results show that direct financing has a significant effect on improving the efficiency of financial support for entity economy.
