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. In the process of concentrated radiation, the value of various resource elements is realized through efficient, orderly and standardized flow, and then through continuous flow scale, it promotes the expansion of regional economic scale and sustainable economic development. The elements of flow economy can be divided into six categories, namely, logistics, information flow, technology flow, talent flow, capital flow and business flow.
Flow economy is an economic model suitable for the development of regional central cities, which mainly means that regional central cities attract materials, capital, talents, technology, information and other resources from outside the region to gather in areas with corresponding platforms and conditions, promote and drive the development of related industries through the reorganization and integration of various resource elements, and radiate the formed and expanded economic energy to surrounding areas and even further areas, so as to achieve the goal of central cities driving the development of surrounding areas. In a sense, logistics is one of the most important development platforms of flow economy, which directly provides fast and convenient services for the development of local economy, and flow economy plays an extremely important role in promoting the large-scale development of logistics business. On the other hand, logistics enterprises are the necessary facilities to promote the flow of resource elements, the driving force to promote the development of flow economy, and play a two-way regulatory role in local economic operation. Therefore, there is a mutual promotion and interdependence between logistics enterprises and flow economy.
The structural system of traffic economy consists of traffic economic elements, traffic economic development subject and carrier, traffic economic development platform and traffic economic development environment. Mobile economic factors refer to the mobile factors that affect the development of regional economy, mainly including material, labor, capital, information and technology, which are closely related to the process of regional economic development and have spatial mobility. The flowing economic subject refers to the economic factors such as logistics, people flow, information flow, capital flow and technology flow, and their basic conditions that are closely related to them. Mobile economic carrier refers to all enterprises, organizations and individuals involved in the allocation of economic factors. The development platform of flow economy refers to the facilities, places and market systems established by central cities to attract the carrier institutions of flow economy and carry out the actual operation of resource elements for these institutions, which is the most important support for the operation and development of flow economy. According to different functions, the traffic economic development platform can be divided into three categories: basic platform, operation platform and service platform. The basic platform mainly refers to transportation and communication facilities, ports, airports, suitable office and living places and other related supporting facilities. Operating platform mainly refers to the factor market system, including commodity market, capital market, futures market, technology market and talent market. The service platform is a market intermediary organization system that provides supporting services for factor transactions and flows, including accounting firms, law firms, asset appraisal firms and enterprise consulting institutions. The development environment of flow economy mainly refers to the social, political, economic and cultural environmental conditions needed to develop flow economy.
