More than 40 percent of chief executive officers who responded to a Kyodo News poll think Prime Minister Junichiro Koizumi's administration should have done more to reform the social security system.

However, more than 60 percent of the corporate leaders said they appreciated the administration's initiative in dealing with bad loans.

With Koizumi stepping down in September, Kyodo asked 100 CEOs in several sectors, including the steel and car industries, to evaluate the administration's achievements. The questionnaire, handed out between late July and early August, allowed them to give multiple answers. The results were released Tuesday.

Forty-one CEOs said reforms to pension, medical care and other social security programs were insufficient, while 64 praised the progress made in resolving the banking industry's bad loans.

To a question on the contentious Yasukuni Shrine, only 25 CEOs answered. Eighteen said they want the Class-A war criminals separated out from the war dead enshrined at the Shinto shrine.
