  1. A dynamic hierarchical description method for workflow is presented. the method provides a dynamic hierarchical way to define a workflow with non - determinate or dynamic factors. with this method, the main process defined at build - time can be reified and extended by the principle of the sub - organizations at either the build - time or the run - time. to ensure the consistency and integrity of the description, a series of constraint rules are also discussed to realize seamless integration between a decomposed process and its original one. this approach supports the description of unpredictable uncertainties, the dynamic hierarchy of business process, and the dynamic modification of enterprise organizations, and all of these improve the flexibility and extendability of workflow management systems dramatically

    長期以來,我國財政與金融的特殊關系使得財政對銀行業實行「特殊」的稅收政策,銀行業整體稅高於製造業以及金融性的服務業,中資金融企業稅高於外資金融機構,過重的稅使得銀行資本充足率難以保證,發展失去后勁;二是我國銀行業和證券業稅制結構不合理、稅制不規范、不科學,銀行和證券業內部不同行業、不同納稅人之間稅收待遇不公平,畸形的稅制必將導致銀行與證券業的畸形發展;三是我國銀行業和證券業稅制與外國稅制的差異,包括征稅范圍大小、稅制的抽象化與具體化、稅制的可操作性、稅收法律力和透明度、稅收執法的嚴肅性等差異,不僅給外資金融機構進行稅務籌劃甚至偷逃稅提供了可乘之機,而且還可能使得外資金融機構對中國市場、對政府政策缺乏信心,而影響其投資,也導致納稅人之間稅不公。
