Abstract Since the beginning of the 21st century, the scale of the digital economy has been increasing, and digital technology with information networks as the core has gradually become an important force to promote economic development worldwide and has profoundly changed the economic activities of different subjects. However, “big volume” does not mean “strong bones.” At the enterprise level, whether the digital transformation of enterprises yields high-quality development characterized mainly by benefits requires further discussion and analysis.
In this paper, digital transformation is included in the heterogeneity model of enterprises. Based on a general equilibrium analysis, we find that under the effect of diminishing marginal productivity, digital transformation does not always have a positive impact on firms' markups, but has an inverted U-shaped nonlinear influence, which first promotes and then inhibits markups. Firm innovation and firm productivity are the key micro-mechanisms for the above effects to play a role. Based on the analysis of typical facts and empirical data of listed companies, the measurement test yields the following results. First, digital transformation can significantly improve firms' markups when it is below a specific threshold value, but it will have a negative impact when it exceeds this value; that is, there is an inverted U-shaped nonlinear relationship between digital transformation and firms' markups. Second, the heterogeneity analysis shows that digital transformation has a greater effect on the markups of state-owned enterprises, export enterprises, and technology-intensive enterprises than on the markups of other firms. Third, digital transformation has an impact on firms' markups through two key micro-mechanisms: enterprise innovation ability and production efficiency.
The innovation of this paper is mainly reflected in the following aspects. First, from a research perspective, this paper discusses the possible impact of the digital transformation of Chinese enterprises on the quality, benefits, and competitiveness of enterprise development, within the context of the digital economy and the specific perspective of firms' markups. Second, in terms of the mechanism of action, digital transformation is included in the heterogeneity model of enterprises. Based on the general equilibrium analysis, this paper proposes an inverted U-shaped micro-mechanism of influence of digital transformation on firms' markups, which first promotes and then inhibits markups. Finally, in terms of research methods, based on the non-dynamic threshold model, this paper estimates the impact of digital transformation on firms' markups and, compared with other approaches, better deals with the endogeneity problem and corporate information disclosure bias, which enhances the credibility of the conclusions. In addition, the multi-dimensional heterogeneity test is conducive to deepening understanding of the impact of digital transformation on firms' markups.
The findings of this paper not only help deepen our understanding and objectively evaluate the impact of digital transformation on firms' markups but also have important policy implications for ways to further improve the quality and efficiency of enterprise development and enhance their market competitiveness through digital empowerment. We make the following recommendations on this basis. First, we must accelerate the digital transformation of enterprises by strengthening the digital thinking ability of enterprises, improving digital application and management ability, and comprehensively and systematically promote enterprise cooperation and digital transformation in the whole value chain, including R&D, design, production and processing, operation and management, sales and services. Second, we must pay attention to grasp the enterprise digital transformation degree. In other words, to grasp the important strategic opportunities brought by digital technology and promote the digital transformation of enterprises, we must pay attention to the “overkill” formed by the law of diminishing marginal productivity. The digital transformation of enterprises in China remains in the initial stages, far from the threshold values or critical points, leaving huge scope for digital transformation to develop. Third, we should optimize the external environment of enterprise digital transformation. Starting from the basic principle of multi-factor cooperation, continuous optimization of external conditions is also an important way to continuously raise the threshold value for possible negative effects of enterprise digital transformation, to lay a necessary foundation for further improving the degree of and space for enterprise digital transformation. Fourth, it is essential to make arrangements for key areas of enterprise digital transformation. The research in this paper shows that there remain important differences between types of enterprises in terms of the quality benefits and competitiveness represented by their markups. These differences may mean that in the future, to grasp the strategic opportunities brought by the progress of digital technology and accelerate the process of promoting the digital transformation of enterprises, it will be necessary to effectively select key areas, departments, and types of enterprises.
