The research on flow economy in academic circles has been relatively mature. Mr. Zhou Zhenhua (2002) put forward the concept of flow economy for the first time in the article Flow Economy and Its Theoretical System, and made a deep study of its theoretical system. In this important paper, he not only creatively summarized the concept of flow economy, but also expounded its main characteristics, structural system, operation mechanism and development stage, which played an important guiding role for later scholars to study flow economy. Since then, there has been an upsurge of studying flow economy in China. Professor Han (2003) further discussed the flow economy on the basis of his research, and had a new view on the connotation of flow elements, which should include seven kinds: logistics, commodity flow, information flow, technology flow, people flow, capital flow and asset flow.
Professor Sun Xiyou (2003) made an in-depth study on the economic development model of Pudong, Shanghai, and combined with the existing theoretical system of flow economy, completed the first book on flow economy in China, which has important reference significance for government departments, theoretical scholars and business people. However, the application research of flow economy is relatively scarce, and the evaluation research of flow economy is even rarer. The only research in China is the index system of flow economy development constructed by Xiao Xianping and Ji Zengping in 2002. In his index system, logistics, capital flow, talent flow, technology flow and information flow constitute the first-level index. Logistics is divided into four levels: domestic trade and international trade circulation, sea, land and air transportation, warehousing, distribution and distribution; The capital flow is divided into four levels: financial insurance securities, attracting foreign capital and domestic capital, and property rights futures trading; The flow of talents is divided into two levels: the introduction and export of talents and the formation of popularity; Technology flow is divided into three levels: technology transaction, transfer and technology development and transformation results; Information flow is divided into three levels: hardware carrier, information dissemination and e-commerce promotion. The above five factors of traffic economy are divided into 16 grades, which are called Grade II. In the overall indicator system of traffic economy, * * consists of three indicators: 13 1.
