A Study On The Impact Of Digital Economy And Human Capital On Green Total Factor Productivity In The Yangtze River Economic Zone

The application of digital economy technologies in concrete production helps to improve the scientific and technical aspects of the production process.In this process it is possible to accelerate the flow of information,save resources and expand the boundaries of production possibilities,thus contributing to an increase in green total factor productivity.Human capital is inseparable from the production process,and when highly qualified people join in their own knowledge reserves and learning abilities often also participate indirectly in production.The higher the level of human capital in a region,the higher the level of absorption,digestion and transformation of science and technology,so human capital also plays an important role in the process of the role of the digital economy on green total factor productivity.The study of the digital economy can be divided into two perspectives: digitalisation of industry and digital industrialisation.There are regional differences in the impact of industrial digitisation and digital industrialisation on green total factor productivity because of the different amounts of initial resources and industries with different advantages between regions,and the differences in the level of human capital will also reinforce such differences.As the Yangtze River Economic Belt is the most dynamic and promising region in China’s economic development process,it is important to explore the relationship between the digital economy,human capital and green total factor productivity in the Yangtze River Economic Belt,in order to help other regions improve their green total factor productivity levels.Using 107 prefecture-level cities in the Yangtze River Economic Belt as data samples and 2011-2019 as the study period,the article selects principal component analysis to measure the digital economy,takes the share of regional higher education students in the total regional population and the EBM-GML index as measures of regional human capital and green total factor productivity,and uses an individual timepoint double fixed-effects model to study the impact of the digital economy on The study finds that(1)the digital economy makes a significant contribution to green total factor productivity without considering regional differences,and that human capital plays an important moderating effect;further refined analysis of the digital economy finds that(2)both the digitalization of industry and digital industrialization have a contribution to After further refining the analysis of the digital economy,it is found that:(2)both industry digitisation and digital industrialisation have contributed to green total factor productivity,and human capital also plays a positive moderating role in it,but the strength of the two effects is different,with digital industrialisation being less strong than industry digitisation,reflecting that the level of technology has a more direct effect on the improvement of green total factor productivity;after considering regional differences,it is found that:(3)the development of the digital economy has the most significant effect on the improvement of green total factor productivity in the midstream region.(4)The effect of industry digitisation on green total factor productivity improvement is most obvious in the midstream,and the effect of digital industrialisation on green total factor productivity improvement is most obvious in the upstream region.The article innovatively subdivides the digital economy into industry digitisation and digital industrialisation to specifically examine how these two refined components affect green total factor productivity in the Yangtze River Economic Belt,and also explores the role of human capital in this process.
