论文摘要
我们回想起历史上承认的经济自由（EF）的先决条件。我们已经检查了908个世界经济自由（EFW）指数的数据点和经济自由指数（IEF）指数的1884分；研究期间分别是2000-2006和1997-2007，从而在柏林墙壁崩溃之后，包括2001年9月11日。在讨论了EFW指数和IEF之后，为了比较这些指数，需要研究其时间和空间的重叠。这使得在2000年至2006年延长的一段时期内进行检查，因此有2组为862个数据点。数据分析与等级大小的法律技术有关。检查分布是遵守指数法还是权力法。与EF公认的主要决定因素的国内生产总值（GDP）相关，遵循区分区域方面，即定义6大洲。半人物情节表明，EFW级的关系对于高级国家（$ \ ge 20 $）的指数是指数级；总体而言，日志图指出了接近权力定律的行为。相反，对于IEF而言，总排名具有指数性的行为。但是，日志图表明，两个不同的权力定律之间存在一个过渡点，即接近等级10。此外，EFW索引与国家GDP的log-log图的特征在于幂律，具有相当稳定的指数（$γ\ simeq 0.674 $）。相反，IEF与该国国内生产总值的IEF关系的日志图指出，随着时间的函数，向下发展的权力定律。显然，这两个研究指标提供了EF的不同方面。
We recall the historically admitted prerequisites of Economic Freedom (EF). We have examined 908 data points for the Economic Freedom of the World (EFW) index and 1884 points for the Index of Economic Freedom (IEF); the studied periods are 2000-2006 and 1997-2007, respectively, thereby following the Berlin wall collapse, and including Sept. 11, 2001. After discussing EFW index and IEF, in order to compare the indices, one needs to study their overlap in time and space. That leaves 138 countries to be examined over a period extending from 2000 to 2006, thus 2 sets of 862 data points. The data analysis pertains to the rank-size law technique. It is examined whether the distributions obey an exponential or a power law. A correlation with the country Gross Domestic Product (GDP), an admittedly major determinant of EF, follows, distinguishing regional aspects, i.e. defining 6 continents. Semi-log plots show that the EFW-rank relationship is exponential for countries of high rank ($\ge 20$); overall the log-log plots point to a behaviour close to a power law. In contrast, for the IEF, the overall ranking has an exponential behaviour; but the log-log plots point to the existence of a transitional point between two different power laws, i.e., near rank 10. Moreover, log-log plots of the EFW index relationship to country GDP is characterised by a power law, with a rather stable exponent ($γ\simeq 0.674$) as a function of time. In contrast, log-log plots of the IEF relationship with the country's gross domestic product point to a downward evolutive power law as a function of time. Markedly the two studied indices provide different aspects of EF.
