How the Digital Economy Affects Industrial Carbon Productivity——A Perspective Based on Technological Progress Bias
As an important driving force for a new round of technological revolution and industrial transformation,the digital econo-my has penetrated into various industries in China,especially the industrial sector,promoted the restructuring of production factors,triggered fundamental changes in the mode of production and economic structure,Based on Acemoglu's(2002)technical suitability theoretical framework,data is included as an element in the constant elasticity of substitution(CES)production function,which in-cludes traditional elements such as capital,labor and energy.By defining the concepts of digital economy,technological progress bi-as and industrial carbon productivity,a theoretical analysis framework of kinetic energy decomposition and impact path of industrial carbon productivity growth is formed.The results showed that the digital economy and technological progress bias may not always promote the growth of industrial carbon productivity,but mainly depend on the changes in technological progress bias caused by the substitution relationship among factors.Further,empirical reseerch results indicate that there is a"U"curve relationship between the digital economy and industrial carbon productivity.However,based on the inflection point values of the"U"curve and the substi-tution elasticity of factors,it can be seen that in the current stage,the digital economy will increase energy consumption intensity and inhibit the improvement of industrial carbon productivity.Technological progress bias can reduce energy consumption intensity and promote the improvement of industrial carbon productivity.Moreover,under the influence of technological progress bias,the digital economy can play an early role in enhancing industrial carbon productivity.
