What the study found
The study found that, in the three years after the 2013 restriction on large firms' participation in public informatization projects, Korean small and medium IT service firms had positive total assets and sales but negative operating profit and net profit. The negative effects were reported as more pronounced for medium-sized firms.
Why the authors say this matters
The authors conclude that the observed effects differ from the original legislative purpose of the large-enterprise restriction system, and they suggest that the policy should be revised.
What the researchers tested
The researchers examined financial performance in Korean small and medium IT service firms for three years before and three years after the January 2013 restriction on participation by firms with cross-shareholding restrictions. They analyzed a sample of 121 firms divided into three groups and used t-tests and one-way ANOVA to compare differences before and after the policy change.
What worked and what didn't
According to the abstract, total assets and sales were positive after the restriction, while operating profit and net profit were negative. The negative effects were described as stronger for medium-sized firms than for smaller firms.
What to keep in mind
The available summary does not describe the firms' exact group definitions beyond being divided into three groups, and it does not provide detailed statistics or effect sizes. The findings are limited to the 121 sampled Korean IT service firms and the six-year period studied.
