In the last ten years China has tried a winning combo: green finance, meaning investments in low‑impact projects, and digital platforms like e‑payments and e‑commerce. A study that examined data from 30 provinces between 2013 and 2023 found that each factor alone lifts GDP. The real surprise is the combined effect: when green finance and digital platforms grow together, GDP rises by 0.0204 % for every extra percentage point of their interaction. In practice, the more firms use digital tools to access green loans or sustainable bonds, the more the economy expands. The statistical model, based on fixed effects and robust errors, accounted for variables such as money supply, public spending, inflation, fixed‑asset investment and industrial structure, isolating the true impact of the green‑digital synergy. The results suggest that policies encouraging both digital innovation and funding of eco‑friendly projects can create a more sustainable and inclusive growth, paving the way for a cleaner, more tech‑advanced future for China and possibly the rest of the world.
The analysis employs a fixed‑effects regression model to control for unobserved province‑specific characteristics, such as entrepreneurial culture or local environmental policies, which could otherwise bias the results. The interaction variable is constructed by multiplying the green finance index (a weighted average of green bonds and green credit) by the digital penetration index (percentage of electronic transactions and online sales volume). This approach captures the synergistic effect, i.e., how the availability of sustainable capital boosts digital technology adoption and vice versa. Control coefficients show that higher money supply and greater fixed‑asset investment are also positively correlated with GDP, while inflation exerts a slight negative impact, consistent with traditional macroeconomic theory. Model robustness was verified through tests for autocorrelation and multicollinearity, confirming estimate reliability. Theoretically, the findings support the “green digital transition” literature, which posits that digitalization reduces transaction costs for green projects, facilitating efficient capital allocation. Moreover, digital tools can enhance transparency and traceability of environmental initiatives, lowering greenwashing risk. From a policy perspective, the results suggest that tax incentives for firms combining green investments with digital solutions, as well as digital training programs for SMEs, could amplify the positive economic effect. Finally, extending the analysis to sectoral level could reveal which industries benefit most from the synergy, providing more precise guidance for governmental interventions.
