None of the top 30 public enterprises have female executives, a corporate analyst said Wednesday, a finding that defies government efforts to raise women's presence in the business world.

According to CEO Score, which tracks companies' performance and management, as of the end of June this year, there were no female executive-level officers among the 139 such officials at the surveyed public firms. There were two women in the C-suite in 2014, but they have retired.

The government had said it wants women to fill up to 30 percent of executive posts. 

The proportion of female executives and employees at public companies has increased throughout the current administration, from 11.5 percent in 2013 and 12 percent in 2014 to 12.4 percent in 2015 and 12.9 percent so far this year. The ratio of women in senior positions, however, has dropped during the years, analysis showed. 

Women in upper-level posts, who would have a chance of becoming executives, accounted for 1.9 percent of the total staff at that level -- 139 females to 7,047 males. Seven of the 30 public entities had no women at that level.

For mid-level positions, 8.5 percent were held by women --4,047 women to 43,292 men.

In terms of the entry- and low-level workforce, women accounted for 19.5 percent -- 9,421 women to 38,797 men.

The Korea Tourism Organization had the highest ratio of women employees at 39.9 percent, 240 out of 602 workers. It was followed by the Jeju Free International City Development Center at 39.1 percent and the Korea Broadcast Advertising Corp. at

29.2 percent. The ratio was the lowest at the Korea Coal Corp. (3 percent)

The number of women in senior positions was the highest at the Korea District Heating Corp. with 6.4 percent. (Yonhap)
