摘要： 我国股票转让所得课税规则的变迁经历了“征税—暂免征收—部分恢复征收—返还部分税收”四个阶段，相应的法律文本为《个人所得税法》、国务院财税主管部门或地方政府的税收规范性文件，核心内容分别是给予、取消以及变相恢复税收优惠。上述规则的变迁反映了税收减免权在中央财税主管部门与地方政府之间的分配及其冲突，这种斜向府际税收竞争越来越激烈。斜向府际税收竞争的产生，源于财政分权不尽规范和规则设计不甚合理等制度成因，它形式上违反税收法定、税收公平和税收效率原则，实质上也侵害了税收征纳各方的合法权益。法律上应当对此进行规制，既要减少税收竞争发生的可能性，又要解决税收竞争引发的问题。

Abstract: The change of taxation rules of income from stocks transfer goes through four stages: imposing tax, exempting from tax for the time being, resuming imposing tax partly and returning part of the tax revenue paid in our country, with the corresponding code of Individual Income Tax Law, and other tax regulatory documents of issued by state tax authorities or local governments respectively, whose core contents，that tax preferences are authorized, canceled and recovered in disguise. Such rule evolution reflects allocation and conflicts of power of tax exemption and reduction among central competent department of finance and tax and local governments ．Originating in system causes such as unsuitable allocation of fiscal power and unreasonable design of rules, the oblique inter-governmental tax completion becomes more and more intense, breaches principles of efficiency in form, fairness and regulated by law of tax, and infringes rights and benefits of taxpayers and the tax authorities in essential. It should be regulated by law, aiming at not only reducing the possibilities of occurrence of tax competition, but also resolving the problems in tax competition.
