许多文献论证了中国实施的积极财政政策并未对民间资本产生挤出效应 ,本文赞成这种观点的同时还认为 ,没有挤出效应仅是积极财政政策增长效应的必要前提 ,并不必然表明具有挤入效应。本文在对积极财政政策增长效应严格细分和界定的基础上 ,进一步分析了中国的积极财政政策没有产生挤出效应的制度原因 ,以及形成挤入效应的制度条件 Many documents argue that the active fiscal policy implemented in China does not have a crowding-out effect on private capital. While this article supports this view, it also holds that without the crowding-out effect is only a necessary prerequisite for the positive effect of fiscal policy growth and does not necessarily indicate that Crowd-in effect. On the basis of the strict subdivision and definition of the positive effect of the fiscal policy, this paper further analyzes the reasons why the active fiscal policy of China does not produce the crowding-out effect and the institutional conditions for the formation of the crowding-in effect
