中国从 1998年开始实施扩张性财政政策,加大对基础领域的投资以来已发行4000多亿元国债。但针对基础领域设施庞大的投资需求,政府的力量是有限的,政府不可能成为投资主体,真正的投资主体应该是企业和社会。如果社会投资没有很好地启动,主要依靠政府发行国债、扩大政府的直接投资来刺激经济增长,其效果只能是暂时的和有限的。民间投资不能启动的根本原因在于基础领域的产业门槛太高,民间资本进入受到市场准入的限 Since its expansionary fiscal policy was implemented in 1998, China has issued more than 400 billion yuan of treasury bonds since it increased its investment in basic fields.
