Abstract
This study investigated the effects of safety and health investments, such as safety and health expenditures for industrial accident prevention, and industrial accident prevention and expenditure on the prevention of industrial accidents based on the results of the 9th occupational safety and health survey. The safety and health investments at workplaces were analyzed through frequency analysis and basic statistics through changes in accident rates by type and size of industries, safety investment costs by size, and safety investment costs. Poisson regression analysis was conducted to determine the impact on accident rate according to the change in safety investment cost. As a result, in both manufacturing and service industries, larger scale generally has lower accident rates. If the investment of safety investment is high, the accident rate is relatively low. In 2018, businesses that had increased safety investment costs than in 2017 had a lower accident rate than those that had decreased.
Keywords : Accident rate, occupational safety and health survey, Poisson regression, safety and health investment.
