The rapid expansion of fictitious assets leads to far more size of fictitious economy than real economy. Incoordination is shown between fictitious economy and real economy.

随着这种经济结构的转变，虚拟资产在经济发展过程中越来越居于主导地位，虚拟资产的迅速扩张导致虚拟经济规模远远超过实体经济，虚拟经济与实体经济呈现非协调发展。

The attitude that we hold to the fictitious capital development should be that: the development of the real economy is the kernel of Chinese economic development, we should satisfy the needs of the development of the real economy better through expanding the quantity and categories of the fictitious capital appropriately; we should pay attention to harmonizing the dialectical relation between fictitious capital and the real economy, so that we can make use of the positive effect of the fictitious capital to the real economy, and prevent the harm that may caused by fictitiousness and capital character of the fictitious capital.

我们对虚拟资本发展的态度：以实体经济的发展作为中国经济发展的核心，通过适度发展虚拟资本的种类和数量来更好地满足实体经济发展的需要；注意协调好虚拟资本与实体经济的辨证关系，发挥虚拟资本市场促进实体经济发展的积极作用，并始终警惕虚拟资本的虚拟性和资本性可能造成的危害。
