广义虚拟经济视角下美国金融部门扩张的效率及影响研究

摘要

虚拟经济特别金融部门规模的扩张，能否更好的为实体经济服务呢？对此，本文在广义虚拟经济视角下，考察了美国20世纪80年代后金融部门扩张的效率和影响，发现当金融部门规模增长过快时，不但会降低金融部门的功能效率，而且还会给本国经济乃至全球经济带来较大的负面影响。因此，本文认为广义虚拟经济视角下，虚拟经济特别是金融部门的发展，不能过分注重规模，而应更加关注其功能的实现，以及服务效率的提高。%Can expansion of virtual economy especially financial sector better serve the real economy? In order to measure that, this paper investigates the expansion of USA financial sector after 1980s; and finds that the over-fast growing financial sector will not only reduce its function efficiency, but also bring great negative impact to the national and global economy. Therefore, we make a conclusion that in the view of Gen-eralized Virtual Economy, ifctitious economy especially the development of ifnancial sector should pay more attention to improve its efifciency and function realization rather than scale expansion.
