我国虚拟经济与实体经济适度发展平衡区间：基于微分向量场方法

虚拟经济源于实体经济的再分配环节，随经济和社会的进步不断发生深刻的变化，对实体经济发展产生深刻的影响。虚拟经济与实体经济存在协调发展的平衡区间，以科学发展观为指导将二者发展保持在相对的平衡区间内，可以有效防范和降低金融风险。因此，在依据经济动力系统模型的基础上，提出了虚拟经济自增值的数理基础及对应的适度平衡区间。

Study on suitable balance relationship between Chinese fictitious economy and real economy---based on method of differential vector fields

Fictitious economy comes from relocation procedure of real economy. Fictitious economy develops continuously with the progress of economy and society, and has profound effect on real economy. There is balance interval for coordinated development between fictitious economy and real economy, if, under the direction of scientific development, development of fictitious economy and real economy can be kept in relative balance interval, financial risks can be prevented and reduced effectively. Hence, based on economy dynamics model, this paper puts forward mathematical basis of fictitious economy self-increment and corresponding suitable balance interval.
