Evolutionary linguistics is going to clarify the evolutionary process of language and evolutionary economics is clarifying the dynamics of economic phenomena. In this paper, we consider the relevance between these two fields. In evolutionary linguistics, the origin of language is thought of as the biological evolutionary process of language capacity of humans and the evolution of language the processes of complexification and structuralization of language structure. The evolutionary process of language forms a double loop dynamics among biological evolution, learning and cultural evolution. This double loop among these three adaptive dynamics ranging in large spatio-temporal scales characterizes language evolution as complex systems. The double loop dynamics can also be found in the origin and the evolution of economics. Thus, evolutionary linguistics and evolutionary economics can collaborate in understanding of complex evolutionary phenomena. The constructive approach is a useful tool to study such complex systems. Communicating the development of methodology and findings to understand such complex systems as language evolution and economic evolution may lead these two fields to fruitful synergism.
