  4. In this perspective, the plans for disneyland and the cyberport in particular have absolutely no direct relation to government accounts and to the budget. it is therefore not surprising that commentators have found it strange that the financial secretary has given these items such a high profile treatment in his budget. it is also not surprising that commentators should ask if this approach is too rushed and whether, in the long run, it will be a " good " thing or a " bad " thing for these projects to be determined prematurely

    有評論指出，財政預算案兼有施政報告的影子，皆因政府以往的一貫做法，是政策已有成熟的全面考慮后，由特首或有關政策科先公布，最後才在預算案中反映出來，尤其是迪士尼樂園及數碼港這類超級計劃，在現階段根本和政府的賬目收支和預算案未見得有很直接的關系，所以難怪論者對財爺在預算案高調處理這些項目感覺意外，質疑這樣的處理手法，是否過份匆忙？
