Spatial network and spillover effect of Chinese digital economy
Abstract
With the vigorous development of digital technologies, digital economy has become a brand economic model, providing a strong driving force for improving the matching of supply and demand, enhancing the allocation of resources, and promoting economic transformation and upgrading.To comprehensively analyze the overall situation of the development of digital economy and the spatial relationship, firstly, the digital economy evaluation index system was established for 31 provinces (municipalities and autonomous regions) in China, and the gravity value was calculated by the revised gravity model to build the spatial network.Secondly, the spatial dependence of regions was explored through the global Moran indexes.Finally, the space-time fixed Durbin model was established to analyze the influence of explanatory variables effected on the development of digital economy and their spatial spillover.The results are as follows: China's digital economy development spatial network is not compact enough.The difference among regions is obvious and neighboring regions depend on each other.The improvement of urbanization level not only promotes the development of digital economy in the province involved, but also indirectly drives the improvement of neighboring provinces, which is a strong spatial spillover effect, while the human capital level has a restraining effect.
