LEGISLATORS critical of the Government's spending spree for the 1993-94 financial year were challenged to name programme areas which should face the axe. Miss Anna Wu Hung-yuk said although some had attacked the Budget for being extravagant, they had not called for cuts in proposed spending. ''Unless they can point to specific areas where spending is not justified, general carping remarks of profligacy are not convincing,'' she said. Although the Budget had been labelled as a political one, Miss Wu noted that it was right for the Financial Secretary Mr Hamish Macleod to be responsive to the needs of the community. ''Just as the advent of 1997 should not be an excuse for spending, so also should it not be an excuse for not spending,'' she said. She said a budget surplus meant the Government was taking more in taxes than necessary, and it was not certain there would be a deficit, which was estimated by Mr Macleod to reach $3.4 billion, in the next financial year. United Democrat legislator Dr Huang Chen-ya also asked critics to name areas in the Budget where expenditure could be reduced. He said most spending items were necessary to maintain the competitiveness of Hongkong in the face of rapid growth in neighbouring Asian countries. Those who rejected the deficit budget because of the present political impasse had ignored the fact that Hongkong would be part of China in four years' time, he said. ''China has absolutely no reason to damage Hongkong, to damage its own economy and prosperity because of its row with Britain,'' he said. But independent Legco member Miss Emily Lau Wai-hing warned her colleagues not to encourage the Government to spend more. ''I was very surprised to hear during the three days of Special Finance Committee meetings that many colleagues were encouraging the Government to spend more money and were inviting officials to come here for more money. ''I could only respond by shaking my head. I don't think this is the behaviour of a responsible councillor. ''I would like to give a message to the Government, not every councillor is that generous. I would not always say 'yes' to your request.'' Mr Eric Li Ka-cheung, Mr Steven Poon Kwok-lim and Mr Henry Tang Ying-yen, on the other hand, called on the administration to have longer term planning of its financial strategy. Mr Poon said the Financial Secretary made a five-year financial forecast last year but this year's medium range forecast covered only four years. ''The rule of the British Hongkong Government will terminate in 1997, but 1997 is only the time for the transfer of Hongkong's sovereignty, it doesn't mean an end to the economic development of Hongkong,'' he said. His concerns were shared by Mr Tang who said the Government had pictured 1997 as a deadline. ''This has cast serious doubts on the level of commitment of the British Hongkong Government to the 5.8 million Hongkong people,'' he said. Mr Li called on Mr Macleod to hammer out long-term financial policies with the Chinese Government for the good of Hongkong.
