Study on the Correlation Between Digital Economy and Green Total Factor Productivity of Manufacturing Industry in Yellow River Basin
摘要
Abstract
In order to investigate the correlation between digital economy and green total factor productivity of manufacturing industry in the Yellow River Basin,a spatial econometric model and a panel threshold model were constructed.Based on the panel data of 73 prefecture-level cities in the Yellow River Basin from 2011 to 2020,the direct effects,spatial spillover effects and threshold characteristics of digital economy on green total factor productivity of manufacturing industry in the Yellow River Basin were explored.The results of the empirical analysis show that a)digital economy is not only conducive to improving the green total factor productivity of local manufacturing industry,but also pro-motes the improvement of green total factor productivity of manufacturing industry in neighboring areas through the spatial spillover effect;b)The direct effect of digital economy on the green total factor productivity of manufacturing industry in the Yellow River Basin is significant in the middle and lower reaches of the Yellow River Basin,and the spatial spillover effect is significant only in the lower reaches of the Yellow River Basin;c)The promotion effect of digital economy on green total factor productivity of manufacturing industry in the Yellow Riv-er Basin is non-linear with marginal increase;d)Knowledge accumulation level will significantly enhance the promoting effect of digital econ-omy on the green total factor productivity of manufacturing industry in the Yellow River Basin,especially when the knowledge accumulation level is higher than the threshold value,the impact of digital economy on the green total factor productivity of manufacturing industry will be greatly increased.关键词
