Abstract: This paper constructs a clean and efficient representative agent model of the data economy from a macroeconomics perspective, in order to analyze the impact of dataization and technological progress on the dynamic general equilibrium of 'consumption-capital', and the catalysis effect of dataization on technological progress. We first set the data in production comes from dataization of the total output of the society and is exponentially functionally related to the technology. Secondly, the data production function is used to solve the optimization problem for firms and households and to construct a dynamic general equilibrium of 'consumption-capital' based on the endogenous interest rate solved by maximizing the returns of firms. Finally, by using numerical simulation and phase diagram analysis, we find that the effects of increasing dataization and encouraging technological progress each exhibit different nonlinear characteristics for equilibrium capital and equilibrium consumption, we thus conclude that dataization enables the positive effects of technological progress on economic development to be more rapid and persistent. We select two types of Chinese policies regarding data openness to represent the role of dataization, and demonstrate the catalysis role of datatization for the development of the digital economy by setting up difference in difference (DID) experiments, which provide persuasive evidence for the theoretical interpretation of the paper.
