TEMPORAL-SPATIAL EFFECTS OF DIGITAL ECONOMY ON HIGH-QUALITY ECONOMIC DEVELOPMENT BASED ON GTWR MODEL
As digital technologies and digital industries are advancing,digital economy becomes a new drive to a high-quality economic development.Study on their relation is of strategic importance in promoting provincial high-quality economic development.This paper,by means of China's 30 provinces/cities'2014 to 2020 panel data,uses entropy weighted TOPSIS to comprehensively score digital economy and high-quality economic development,applies spatial auto-correlation test and hotspot to analyze their spatial distribution on the basis of their temporal-spatial instability,and employs GTWR model to discuss their temporal-spatial response law between digital economy and China's provincial high-quality economic development,and analyzes the path of digital economy to a provincial high-quality economic development.Digital economy has a strong spatial auto-correlation with high-quality economic development,with their hotspots concentrating on central and eastern China,and cold spots on western China.The spatial concentrating intensity of digital economy is diminishing while that of the high-quality development is maintained at a high level.Digital economy can outstandingly promote a high-quality economic development with impacting factor of temporal-spatial heterogeneity,showing a declining trend from south-eastern coastal to northwestern continent spatially,and a diminishing provincial difference to regional coordinated development.Digital economy variably drives the sub indicators of high-quality economic development,weakest on innovative development.This paper presents suggestions on further advancing regional coordinated development of digital economy in western China,promoting high-quality economic development through innovation,and promoting provincial high-quality development through digital economy.
