Abstract:In recent years, construction robots, as an important symbol and key technology for the transformation and upgrading of the construction industry, have become the focus of research. However, the current construction robot industry chain is still unclear and the industrial ecology is relatively chaotic. From the perspective of industrial ecosystem, this study constructs a symbiotic evolution model of the construction robot industry ecosystem based on the logistic equation and the Lotka-Volterra equation, and simulates the construction robot industry entities under various symbiotic evolution modes. At the same time, an empirical analysis of the symbiotic evolution of the two main bodies in the Chinese construction robot industry ecosystem was conducted. The study found that: (1) China's construction robot industry ecosystem is in its early stages of development and has great development potential. (2) The size of the symbiosis coefficient affects the equilibrium results of the symbiotic evolution of the construction robot manufacturing entity and the application entity. When in a mutually beneficial symbiotic mode, the two promote each other and can achieve the effect of "1+1>2". (3) China's construction robot manufacturing and application entities are in a parasitic symbiotic mode, which is not the best symbiotic pattern. In order to achieve the most ideal mutually beneficial symbiotic model, more resource integration and value co-creation are needed to promote symbiotic evolution. To this end, this study proposes that the construction robot industry is a technology integration industry, and it should promote human-machine collaboration and strengthen upstream and downstream collaboration, in order to provide a theoretical basis for guiding the healthy development of the construction robot industry ecosystem.
