Dividend differentiation, latecomer advantage and diminishing returns: the heterogenous impact of digital technology progress on China’s economic modernization
利用2013-2023年中国30个省份面板数据，发现数字技术进步整体推动经济现代化，但对经济创新、绿色化、开放和产业现代化的影响存在分化，且呈现后发优势与边际递减特征。
Advances in digital technology are driving a new modernization of economic systems, but the impact is clearly heterogeneous. This study pioneers an economic modernization index evaluation system from the four dimensions of economic innovation, economic greening, economic openness and industrial modernization, and quantitatively analyzes heterogeneous impacts of digital technology progress on economic modernization by panel fixed effect model and threshold regression model, utilizing 11-year provincial panel data (2013–2023) across 30 China’s provinces. The general findings discover that the progress of digital technology has significantly propelled the construction of China’s economic modernization in general. However, in the sub-dimensions of economic modernization, the promoting effect of digital technology progress on economic innovation is stronger than its impact on economic modernization and greening, while the impact on economic openness is not significant and there is an obvious differentiation phenomenon. At the regional level, the promoting effect of digital technology progress on economic modernization is larger in China’s western region relative to eastern China, and stronger in regions with lower level of economic modernization in comparison to regions with higher level, showing a latecomer advantage. Moreover, the enhancing effect of digital technology progress on economic modernization also has the nonlinear feature of “diminishing marginal effect”. Such findings can offer government policy-designer insights in coordinating the use of digital technology dividend, narrowing the regional development gap, identifying the weak points of digital technology dividend, and accelerating the national economic modernization.
