Financial Secretary Henry Tang Ying-yen looks unlikely to pull any surprises in his maiden Budget scheduled for Wednesday, according to analysts. 'There won't be a lot of new thinking. Too many surprises or new initiatives will be too much for society to digest now,' said Francis Lui Ting-ming, a leading economist at the Hong Kong University of Science and Technology. He predicted, however, Mr Tang would approve the issuing of bonds for infrastructure. 'This is one of his babies. He is keen to do it as an additional source of revenue. 'The other one is a general sales tax [GST]. It's a question of when will be the best time to do it. It won't be popular. He has to take account of his own political future,' said Professor Lui. Preparation for the introduction of a consumption-based tax has been speeded up after Mr Tang took over from Antony Leung Kam-chung last summer. In his Budget speech, Mr Tang is expected to give strong inclinations towards introducing the tax as a long-term measure to broaden the tax base and secure stable revenue. A detailed report is due by the end of this year. Legislator Eric Li Ka-cheung, who represents the accountancy functional constituency, said: 'There won't be a lot of major initiatives in the next year. He's lucky. The economy has begun to turn the corner. There's no immediate pressure for him to tackle the deficits. He can afford to take a respite.'
