Major South Korean businesses cut their investment in the first half of this year by nine billion U.S. dollars.
According to industry tracker CEO Score, the main factor was the slump in the global semiconductor and display industries.
Of the 353 businesses surveyed, investments in the first half totaled 30.three billion dollars, an on-year decrease of 23 percent.
Making the biggest cuts were Samsung Electronics, SK hynix and LG Display.
But in telecoms, there was an increase in investment by companies such as KT and SK Telecom with the roll out of their respective 5G networks.
