Empirical analysis on input and output of regional digital economy under the development level of"internet+"
To address the impact of"Internet Plus"on the digital economy,this paper constructs a digital economy indicator system from the perspective of input and output,measures the data samples of 30 provinces and cities in China from 2014 to 2020 by using entropy weight TOPSIS method,and explores regional heterogeneity through the panel cointegration test and error correction model method.digital economy input and output under the development level of"Internet+".The research shows that the development level of"Internet+"has become a long-term driving force for the improvement of input and output of the digital economy,and focusing on its combination will help to better play the innovation spillover effect of"Internet+".There is heterogeneity in the impact of"Internet+"development level on the output input of the digital economy,and the long-term promotion effect in the eastern region is significantly greater than that in other regions.There is a short-term heterogeneous correction effect on the long-term equilibrium impact of"Internet+"development level on the input and output of digital economy,and the lagging effect also has significant heterogeneity characteristics.The research conclusion provides a reference for the improvement of the input-output level of digital economy and the cultivation of enterprise innovation ability in various provinces.
