The principal aim of this study is to discern the implications of technology shocks in the sphere of cross-border e-commerce on the macroeconomic indices of South Korea. Leveraging Bayesian estimation techniques, we scrutinized quarterly data from the inaugural quarter of 2000 through to the first quarter of 2022 to perform an empirical exploration. Deductions drawn from the impulse response function indicate that a positive perturbation in the technology of sustainable cross-border e-commerce production instigated a swell in output and investment for both non-tradable and cross-border e-commerce goods producers. Conversely, the sector of traditional tradable goods exhibited a decrease in output and investment. Additionally, this favorable technology shock appears to have amplified household consumption and employment, along with wages in the non-tradable and sustainable cross-border e-commerce goods sectors. In stark contrast, the traditional tradable sector demonstrated a decline in household consumption, employment, and wages. Intriguingly, the technology shock also exerted an influence on the pricing system, causing a rise in the prices of non-tradable goods and cross-border e-commerce goods. On the other hand, the prices of traditional tradable goods experienced a downward turn. These insights provide a pathway to an understanding of how advancements in sustainable e-commerce technology can mold an array of macroeconomic factors in a digitally evolved economy such as South Korea.
