Analysis of the Effect of the Ordinance on the regulation of Hakwon Teaching Hours by Province

This study used data on the average monthly private education expenditure per student in each municipal unit to examine the extent to which regulation of cram school hours at the high school level was effective in reducing private education expenditures. As a result of the analysis using the difference in difference(DID) method, it was found that the regions that changed the Hakwon(private after school institution) and private tutoring teaching hours to 10pm did not have a statistically significant effect on the decrease or change in private education expenditures after the implementation of the policy compared to other regions. However, as a result of the multiple regression analysis by setting specific dummy variables for each period of the 10pm, 11pm, and 12pm regulation time, it was found that the average monthly private education expenditure per student in the 10 pm regulation area was 248,900 won (all high schools) and 323,800 won (general high schools) less than in the 24-hour restricted area at a significance level of a=0.1. If the 11 provincial education offices limit the teaching hours of high schools to 10 p.m., it will be calculated as a reduction of about 162.6 billion won per year. This is equivalent to about 2.2% of the total high school students' private education expenditure of 7538.9 billion won in 2023. There is a need to conduct various policy evaluation studies on the effect of regulating Hakwon or private tutoring teaching hours in the future and the effects of regulatory policies announced and promoted last year.
