Reporting quality and quantity in Japanese government tenders

This study looks at how the amount and quality of corporate financial reporting relate to success in Japanese government procurement. Using recent central government tender data, the analysis compares competitive and non-competitive tenders and checks whether political connections change the effect of disclosure.

Results show that firms with more and better reporting are more likely to win in competitive tenders, while reporting has no clear effect in non-competitive awards. Political connections weaken the link between disclosure and contract success, suggesting that informal ties can substitute for formal transparency.

What the study examined

The research explored whether the amount and the quality of companies’ financial reports matter for winning government contracts in Japan. It compared cases where firms competed openly for contracts to cases where competition was limited or absent, and it also looked at whether political ties change the role of disclosure.

Key findings

The analysis found a clear pattern in competitive tenders: firms that provided more extensive reporting and higher-quality information were more likely to win contracts. In contrast, reporting did not predict success in non-competitive tenders.

• Greater quantity of reporting correlated with higher win rates in competitive settings.
• Higher reporting quality was also associated with better procurement outcomes when bids were contested.
• Political connections reduced the importance of reporting, indicating that such ties can act as a substitute for formal transparency.

Why it matters

These results highlight how formal disclosure can improve outcomes when procurement is truly competitive, by making information about firms more usable to decision makers. At the same time, the weakening effect of political ties points to institutional realities where informal relationships can overshadow documentation.

The findings suggest that efforts to strengthen transparency and reporting can support fairer, more efficient public contracting in environments where competitive processes are enforced. They also underscore potential risks where political influence diminishes the value of public disclosure.
