I FIND it necessary to respond to Candy Wong's ''Inside Politics'' article (Sunday Morning Post, April 18). In this piece, she strings together a number of cliches about the policies and work of the Housing Authority for the purpose, it appears, of making a case for attacking the record of the authority under the chairmanship of Sir David Akers-Jones, and to advocate a different form of authority. Ms Wong starts her piece with the authority's housing subsidy policy, a policy rooted in the principle that tax-payers' money in the form of subsidies should go to those most in need, and which should be reduced for those who no longer require it. Fortunately, the majority of people in Hongkong, including public housing tenants, are sensible enough to recognise the equity of the policy. This is perhaps helped by the fact that even on paying double rent the median rent-to-income ratio is still about eight per cent. On the scheme to sell flats to sitting tenants it is a little hard to agree with her assertion that the authority is out of touch, since the scheme was a response to an undeniable, growing demand for home ownership expressed by the constantly high over-subscription to the authority's home ownership scheme, and followed extensive public consultation. Perhaps the scheme, in the context of all the authority's avenues to home ownership, might not have found the right niche, but the authority surely cannot be faulted for trying the idea. The Housing Authority is responsible for implementing the Government's, not the authority's, long-term housing strategy, so it is appropriate for the authority to be seen to be doing this. With regard to openness and responsiveness, all full authority meetings are open to the public, and its committees held 51 meetings with various interest groups during 1992. In addition, all major issues such as the housing subsidy policy, sale of flats to sitting tenants and so on have been the subject of public consultation and discussions in Legco. I cannot think of any other public body in Hongkong with such a record of contact with the people it serves. The authority has led the Hongkong construction industry in embracing international quality assurance standards and, as a result of its initiatives, Hongkong has the largest single concentration of construction companies certified to the International Standards Organisation Code 9000 for quality assurance. The department's Construction Branch is on schedule to achieve the same level of quality assurance in July this year. FUNG TUNG, Director of Housing.
