Prior studies have pointed out that the Japanese economy has lagged behind in IT and has not fully enjoyed the productivity benefits of IT investments, which has led to a prolonged slump in productivity growth to some extent. The spread of COVID-19 is forcing the Japanese economy to undergo digital transformation (DX), but there has been insufficient prior research in Japan on the impact of DX on corporate performance. This study analyzed the relationship between DX and corporate performance using firm-level data. The main findings are as follows: (1) IT investment is positively correlated with firm productivity, with the main contribution coming from software; (2) the establishment of a concurrent Chief Information Officer (CIO) is positively correlated with firm productivity, but the complementary relationship between CIO and IT investment is not confirmed; (3) there is no direct relationship between the introduction of new devices such as smartphones and tablets into the workplace and firm productivity; (4) there is no significant relationship between the use of big data within a company and productivity improvement; and (5) sharing data with supplier companies is positively related to corporate productivity, while sharing with customers is negatively correlated with firm productivity; and (6) IT investment by the Japanese headquarters has a weak positive correlation with the profit margin of overseas subsidiaries.
For this study, we connected and analyzed firm-level data from the "ICT Workplace Survey", the "Basic Survey of Japanese Business Structure and Activities" and the "Basic Survey on Overseas Business Activities" conducted by the Ministry of Economy, Trade and Industry (METI), the "Survey on Big Data Utilization and Innovation in Manufacturing" by RIETI and firm-level data provided by Tokyo Shoko Research (TSR)".
