In modern society, industrial needs for skill are becoming sophisticated, but the expansion of higher education since 5.31 Education Reform has caused a variety of social issues in Korean society such as youth employment problem. Therefore, this study has estimated the scale of highly educated human resource over college graduates required in our society by using the information that dictionary of occupational titles(DOT) provides. Human resource scale of academic level required by occupations was estimated by three-digit sub-category, thereafter, division, main category, or total.
Estimation was carried by the method of calculating the population of the required human resources scale by occupation through combining DOT data with “Regional Employment Survey” data. However, “Regional Employment Survey” has three-digit occupation information for each individual, while the DOT is composed of occupations in four-digit sub-categories. Therefore, a procedure for converting the four-digit sub-categories in DOT into three-digit is necessary. But there is no information such as the number of employed workers by four-digit occupation, this paper used the mode of education level required by four digit occupation first, and then adjusted the extracted human resource scale of required education level by occupation by using the mean value of required education levels.
This estimation method is an advanced one that is differentiated from the prior studies’ method, and the significance of this study is in the points that it calculated the human resource scale of required education level by occupation for the first time.
