Research on the Effect of Information Infrastructure Construction on Low-Carbon Technology Knowledge Flow

The cross-regional diffusion of low-carbon technology knowledge is conducive to the development and increases emission reduction contribution wider land. However, flow faces many obstacles such as information, geography, local protectionism. This paper focuses on whether how information infrastructure construction can promote under digital wave. Through patents category Y02 classification standard Cooperative Patent Classification (CPC) by matching them city level measure flow, empirical research finds that: cannot only directly but also indirectly increasing foreign direct investment human capital. role in promoting more obvious central western regions non-resource-based cities. Finally, view current situation flows China, puts forward policy recommendations vigorously infrastructure, gradually increase network density number nodes, release economic dividend, form a spatial pattern coordinated regional flows.
