Abstract:Regional knowledge carrying capacity refers to the ability of regional knowledge resources to promote regional economic development and scientific and technological innovation, and it is an important indicator of regional innovation sustainable development. This paper evaluates the regional knowledge carrying capacity from the perspective of innovation value network. Firstly, it constructs the innovation value network from three aspects: subject resource system, science and technology innovation system and innovation environment system. And establish the regional knowledge carrying capacity evaluation index system based on the structure of innovation value network. Then using AHP-DEMATEL method to set the weight of each index, this method integrates the influence degree and the influence degree of each factor into the weight, reducing the limitations of single evaluation by experts scoring. Finally, we make an empirical analysis for regional knowledge carrying capacity in Southeast and South Asian countries along “the Belt and Road” and put forward corresponding suggestions.
