安徽省财政收入与经济增长的回归模型分析

1、安徽省财政收入与经济增长的回归模型分析摘要：财政收入与经济增长之间存在着高度的相关性，本文在相关经济学理论的基础上，对安徽省财政收入与经济增长间关系做了实证分析，并得出结论，要保持一地区或一个国家经济的可持续增长，财政收入与经济增长之间应形成相互依存的长期稳定关系关键词：财政收入，经济增长，回归分析财政收入与经济增长之间存在着相互依存、相互制约的关系，正确认识二者之间的关系,对促进我省经济增长有重要作用。一.理论分析财政收入是政府部门的公共收入，表现为政府部门在一定时期内所取得的货币收入。在西方经济学教科书中，国内生产总值（GDP是指经济社会（即一国或一地区）在一定时期内运用生产要素所生产的全

2、部最终产品（物品和劳务）的市场价值，是国民经济活动最终成果的总量指标。研究过财政收入与经济增长之间关系的学者很多。最先比较明确提出国家财政税收原则的是威廉配第，他在代表作赋税论中，比较深刻地分析了税收与国民财富、税收与国 家经济实力之间的关系。亚当斯密在其著作国富论一书中，综合了自由主义学说的观 点，主张对经济实行自由放任的政策， 认为政府应当减少干预或者不干预，政府只应作为“守夜人”存在。斯密之后，许多经济学家从不同角度提出了不同的财政税收观点，比如瓦格纳 在其代表著作 财政学中提出了社会政策的财政理论，认为财政收入增长能够随着经济增长自动增加。哈勃格计算了税收的超额负担，进而发现课税扭曲了

3、消费者对课税商品与其他 商品的选择。我国学者高培勇认为，应当根据实际情况合理科学地确定财政收入和财政支出， 不能简单的量入为出。税率或负税一个地区或一个国家要保持经济的可持续增长，财政收入与经济增长之间应形成相依相存的长期稳定关系，并且，只有合理的财政收入水平才能对GDP勺增长产生积极的影响，这一命题可以根据拉弗曲线得以证明。在经济学界，美国供给学派经济学家拉弗知名度颇高， 以其拉弗曲线”而著称于世。拉弗曲线表明：在税率增长的初期，GDP迅速增长；当税率增长超过某一点，尽管其增长率不变，但GDP的增长率迅速下降， 甚至出现负增长，图中表示为EB线段。当税负大于A点时，过高的税率反而导致政府税收

4、收入的减少，长期来看会抑制居民消费、储蓄和投资的积极性，从而抑制经济的可持续发展，因此ABC区域被称之为“禁区”，政府部门需要在OAC区域征税。二实证分析安徽省财政收入与生产总值表年份财政收入（亿元）生产总值（亿元）199052.89658.02199148.18663.60199255.14801.16199373.211069.841994108.761488.471995147.002003.581996193.142339.251997230.812669.951998262.072805.451999280.852908.592000290.422902.092001309.5532
