摘要

The externality of knowledge creates knowledge spillover. The spatial spillover of knowledge enables the innovation activities to interact with each other in the region, creating a spatial connection of innovation. This connection will affect the regional innovation performance at the spatial level. This paper constructs a theoretical model of the impact mechanism of innovation spatial connection on regional innovation performance. On this basis, the gravitational model is used to measure the degree of innovation spatial connection in the Yangtze River Delta urban agglomeration, and the spatial econometric model across the Production Function is used to consider the impact of the innovative spatial connection of the Yangtze River Delta urban agglomeration on regional innovation performance improvement. The study finds that the innovation of the Yangtze River Delta urban agglomeration mainly revolves around several important nodes, and gradually forms a hierarchical structure of multi-level innovation spatial connection. The innovative spatial connection has a positive adjustment effect on regional innovation performance Improvement. The technology distance dimension has a more significant effect on the regional innovation performance improvement than that of geographic distance.
