This study examines relationships between digital technology adoption, innovation, and firm performance using data from 1,028 Vietnamese enterprises surveyed in 2023. We extracted and analyzed data from the World Bank Enterprise Survey global dataset, creating 23 enterprise segments across firm sizes, sectors, regions, and characteristics.
Using correlation analysis with statistical significance testing, we identify which digital tools link most strongly to performance outcomes. Results reveal three key findings. First, electronic payment systems have the strongest link to performance. Both sales and purchase payment digitalization correlate at 0.77 with productivity growth (p<0.001). Second, a clear digital gap exists across firm size. Website adoption reaches 66.3% among large firms but only 42.3% among small firms. Third, digitally advanced segments grow through productivity rather than employment expansion.
The findings offer clear policy direction. Electronic payment infrastructure deserves priority investment given its robust links to both productivity and revenue growth. Small firms need targeted support to overcome adoption barriers. Credit access correlates strongly with process innovation (r=0.65, p<0.001), suggesting financial support can accelerate capability building.
Keywords: digital adoption, firm innovation, innovation performance, technology adoption, Vietnamese enterprises.
