The conceptual model of the national blue economic system and its modeling principles: A supernetwork perspective

Abstract

The national blue economic system is a complex system formed by the correlation of different agents, such as related blue industries, blue products, blue firms and blue provinces in a country. Its essence can be regarded as a complex system formed by the interconnection of a variety of heterogeneous networks. The supernetwork is an important method for studying such multilevel, multidimensional and multiagent correlation problems in network science. This method can effectively assess the intra- and interrelationships of each element entity. This paper incorporates the multielement entities in the national blue economic system into this multilayer network framework for systematic analysis and decomposes the development issue of the blue economy into the development issues of blue industries, blue products, blue firms and blue provinces. On this basis, this paper analyzes the conceptual model of the national blue economic system space, qualitatively describes the intra- and interexport relationships among multifactor entities in national blue economic development from the perspective of the multilayer network, and expounds the modeling principle of the national blue economic system space. This supernetwork approach provides effective new methods and tools for countries to study the development of the blue economy and formulate corresponding policies to achieve blue growth.
