二、英国的重商主义
Part One
作者还主张振兴农业,而办法是力图减少放牧的收益和提高农业的利益。
作者认为当时英国的主要问题是物价上涨、国家财富耗竭、圈地运动造成的社会后果和城乡的普遍凋敝。而所有问题的真正根源是铸造成色不足的货币。因此,作者提出货币的铸造一定要在质和量上都保持正确的、应有的比例,国家应禁止输入对英国没有价值的商品,限制未加工的商品(尤其是羊毛)输出海外,鼓励加工过的商品输出国外。
《英国得自对外贸易的财富》一书,在100年之内,一直是重商主义的福音书。因此,如果说重商主义有一部划时代的著作,……那么这就是托马斯·孟的著作。
--《马克思恩格斯全集》,第20卷,人民出版社,1971年版,P253
贸易差额论
01
对外贸易顺差使国家致富的唯一手段
02
“对外贸易是增加我们的财富和现金的通常手段,在这一点上我们必须时时遵守这一原则:在价值上,每年卖给外国人的货物,必须比我们消费他们的为多。”
ห้องสมุดไป่ตู้
与之相伴的是西欧各国封建中央集权国家的逐渐发展和完善。要建立起强大的国家,必须努力开发利用本国资源,依靠最为有效的手段创造和积累财富。因此,增加国家的财富和权力是政策的目标,经济政策的目标是获得最大的公共收入,供宫廷和军队消费,对外政策的目标则是征服。这种积累财富的目标就使国家关心能获取财富的一切来源,表现为国家对于整个国民生活、国民经济各部门的控制和管理。
16世纪下半叶-17世纪中叶

主张改变禁止货币输出的政策,要求在对外贸易中保持顺差。

西方公债理论

02
穆勒(1806-1873)的公债理论 公债对经济的影响应从来源和用途两方面具体分析。 公债资金来源于生产领域,而用于非生产领域。这种公债制度是最坏的政府筹款方法。 公债资金来源于国外或国内游资,而用于非生产领域。这种公债制度可以不受到严厉排
斥。 公债资金来源于生产而用于生产领域,这种公债制度不应受到指责。
障费用的增加。
第五节 马克思的公债理论
公债是财政筹资的一种手段。
公债对资本主义制度的形成 和发展起了重要的推动作用。
论述了公债与赋税的关系。
揭露了公债在资本主义社会 的剥削性。
第六节 李嘉图等价定理的争论
李嘉图等价定理的含义
征税和发行同等数量公债都会使一国生产资本同等 数量减少。
在发行公债的情况下,每年由政府偿付的利息,只 不过将一部分人的收入转付给另一部分人而已,并 不改变一国财富的存量。

提议以市场利率的升降与否作 为衡量公债危害程度的方法。
对传统公债理论既有继承,又 有发展。
他尽管保留了一定的公债有害 的看法,但已与古典经济学的 公债有害论立场产生了很大的 距离,开始赞同在存在过剩闲 置资本前提下发行公债的主张。
国际人权保护与国家主权和不干涉内政原则的关系

论国际人权保护与国家主权和不干涉内政原则的关系【摘要】国家主权作为当代国际法最基本、最重要的原则,在国际关系上具有最高的权威。
但是,国家之间的主权是平等的、相互的,一个国家在行使主权时,不得侵犯他国主权。
人权在本质上属于一国内部管辖的事项。
但是同时,人权又不是纯粹的一国之事,人权的国际法保护已是趋势,人权具有国际性。
互不干涉内政原则,是从国家主权原则派生出来的又一项国际法基本原则。
【关键词】国际人权国际主权不干涉内政国际人权保护与主权原则和不干涉内政原则三者是辩证统一、密切联系的,而不是截然对立的。
一方面,主权原则和不干涉内政原则是国际人权事业健康发展、人权保护切实有效的基础;另一方面,主权原则和不干涉内政原则不能成为对抗国际人权措施的依据。
首先,国际人权保护是指国家和国际组织根据国际人权条约,为实现基本人权的某些方面承担特定的或普遍的国际合作义务,并对违反国际人权条约义务、侵犯人权的行为加以防止和惩治的活动。
主权原则是处理国际关系最基本的原则,自然也是国际人权保护应遵守的原则。
人权在本质上属于一国主权范围内的问题。
个人的权利主要通过国家来保障和实现,亦即保护人权的主要责任在于主权国家。
各主权国家有权根据本国国情选择人权的实现模式和发展道路。
国际人权保护实质在于国际法提供国家尊重、促进和保护人权的合作机制与程序。
离开国家,不可能解决任何人权问题。
没有国家之间的合作,人权的促进和保护也就无从谈起。
因此没有国家主权,人权也就无法得到切实保障和实现。
所以,国际法上人权原则的确立绝不意味着人权高于主权。
任何国家不得利用人权问题干涉他国内政,强行推行自己的社会、政治制度、发展模式和价值标准。
虚浮哦国际文件一再重申,任何国家或国家集团均无权以任何理由直接或间接干涉任何其他国家的内政或外交事务。
“人权无国界”或“人权高于主权”的理论混淆了人权的本质,夸大了二者的对立,实际上是为干涉政策服务的理论工具。
同时,人权具有国际性,主权也不能成为国家无视国际人权义务、侵犯人权的盾牌。

T20型铁钻工在保留手动操作的基础上,针对频繁㊁枯燥的上卸扣作业,研制了自动上卸扣功能,基于安全考虑,自动上卸扣的流程可以随时手动终止,自动上扣流程图如图6所示㊂图6自动上扣流程图F i g.6F l o w c h a r t f o r a u t o m a t i c m a k i n g-u p c o n n e c t i o n自动上扣操作时,立柱升降和伸缩臂的伸缩动作相对比较危险,在手动控制立柱高度和伸缩臂到位后,通过一体化司钻座椅或者遥控器发送自动上扣指令,铁钻工本体P L C将自动执行上扣流程程序,其中每一步的执行依赖主机本体安装的传感器进行判断,例如冲扣模式的背钳和冲扣钳的夹持,是通过各自的压力传感器判断是否夹紧,在夹紧压力达到设定压力后程序自动转到下一步作业程序㊂自动上扣功能在一定程度上减轻司钻人员工作强度,并能保证设定的拧紧力矩,从而减少人工操作所带来的拧紧力矩差异㊂自动卸扣流程与自动上扣流程基本相似㊂9孙军盈等:D T 20型铁钻工电液控制系统的研制第25卷

论经济主权
论经济主权卢麒元2013-06-03作为一个半殖民地国家,中国人对主权问题是十分敏感的。
毛泽东1949年在天安门城楼上庄严宣誓:中国人民从此站立起来了!其内涵主要就在於主权回归了。
毛泽东领导的中国主权回归包括双重含义:第一,国家主权的回归;第二,人民主权的回归。
毛泽东总结自己的一生做了两件事:战争与革命。
这两件事情,恰恰就是重建双重主权。
可惜的是,这两件事情并不完全能够被国人理解。
因为不理解,甚至是曲解,遂有了对毛泽东的否定。
对毛泽东的否定,一旦上升到理论高度,就演变成了新自由主义滥觞。
其结果,就是上个世纪九十年代开始的极端改革开放。
极端改革开放的意思,就是改革开放到了严重侵蚀双重主权的程度了,甚至已经到了直接冲击宪政基础的地步了。
要知道,中国的宪政基础,就是国家主权和人民主权。
笔者知道,在今日中国讨论主权问题是极端困难的。
因为,这涉及对革命和改革的清晰定义和重新梳理,也涉及对历史人物的评价,太过敏感了。
如果说,毛泽东的战争与革命,是为了建立中华人民共和国的国家主权和中国人民的人民主权;那末,邓小平的改革开放,理应是为了实现国家主权和人民主权的效用最大化。
毕竟,共产党领导的改革不应是对战争与革命的简单逆反,而应当是对战争与革命的补充与完善。
如果,将改革简单化为对革命的逆反,那就意味着国家主权和人民主权的双重丧失。
那样,执政党将立刻丧失执政的伦理基础。
事实上,我国当代思想家并不成熟,他们容易从一个极端走向另一个极端。
当改革开放走向极端主义形态的时候,他们必然会走向对战争与革命的全盘否定。
由於极端改革的出现和发展,我国再次出现了双重主权危机,国家主权再次被严重侵蚀,人民主权再次被严重蚕食。
至此,改革开放的终极意义开始遭到人民质疑了。
於是,中国开始出现所谓的“左翼”和“右翼”的交锋,中国开始出现对於“革命”和“改革”的激辨。
说到底,这是人民和精英之间开始撕裂和对抗了。
对抗的焦点,当然是主权问题。
套用精英的话语,这是一个民主问题。
论民族自决与国家主权的关系
论民族自决与国家主权的关系作者:石晨来源:《中国·东盟博览》2014年第03期【摘要】作为国际法的两项基本原则,民族自决原则与国家主权原则之间的关系已成为国际法中一项重要课题,具有十分重要的现实意义,直接关系到主权国家的稳定与统一以及整个世界的安全与和平。
国家主权始终是国际法和国际社会的基础,民族自决必须要以尊重国家主权为前提,只有正确处理好国家主权与民族自决权的主次关系,才能保证国家的统一,抑制极端的民族主义,保持国际社会持久的安全与和平。
【关键词】国家主权;民族自决;关系一、国家主权的产生国家主权的概念产生于16世纪后半叶,法国政治思想家博丹提出关于中央集权的国家主权学说,认为主权是国家的重要标志,是一种永久的和绝对的权力,这种权利不能转移,除受上帝和自然法律以外,它不受任何限制。
博丹的主权学说,对于铲除中世纪末期的贵族割据势力,反对教会特权,建立君主专制的中央集权制国家起着积极的作用。
但随着资本主义生产关系的巩固和发展,国家主权说越来越不能适应资本主义发展的需要,于是卢梭的人民主权学说便应运而生。
他强调国家主权属于人民,是公共意志的运用,认为主权不可转让、不可分割,是绝对的、至高无上和神圣不可侵犯的。
19世纪末和20世纪初,由于旧的民族国家已经阻碍垄断资本主义的发展,垄断资本的扩张要求打破一切民族和国家的界限,于是否定和弱化国家主权的理论开始抬头。
19世纪末,德国甚至出现了一种极端的国家主权说,宣称国家只服从自己的意志,而可以无视国际法,这就为德国这样的新兴帝国主义重新瓜分世界提供了理论。
这种理论曾被德国法西斯所利用,给人类带来了惨重的灾难。
联合国成立之后,通过制定一系列国际文件对国家主权原则的规定,从法律上奠定了国家主权原则的重要地位。
二、民族自决权的由来民族自决权的概念起源于西欧,是17—19世纪资产阶级民主革命的历史产物。
17世纪,英国思想家洛克以“天赋人权”原则为基础,论述了只有人民的同意才是建立国家政府的基础,认为如果是征服者强加于被征服者的政府,那么被征服者的后裔有权摆脱这个政府。
革命与暴政的悖论:暴君挑起革命、革命抛弃暴君
革命与暴政的悖论:暴君挑起革命、革命抛弃暴君作者:姜守明来源:《历史教学·中学版》2019年第03期编者按:17世纪英国史充满革命的话语,这是英国史上难得的独特现象。
这百年间,英国发生了数次内战、审判国王、创建共和、摄政独裁、王朝复辟与宫廷政变等一连串轰轰烈烈、惊心动魄的大事件。
通过内战和革命,英国掀翻了封建专制制度,在恢复混合君主制传统的基础上,实现了从主权在君(王)到主权在民(议会)的转变,为现代代议民主政治开辟了道路。
尽管这场绝无仅有的革命早已走入历史,但它的影响并未尘封,而且还留下了许多悖论,至今让人着迷。
诸如:为何挑起革命者既不是下层群众、也不是上层议会反对派,而是专制国王?为何克伦威尔既充满神圣的清教理想、又具有反专制的革命热情,却走上了军事独裁的不归路?为何1688年宫廷政变既孕育于暴力之中、又带有暴力性质,却被称为“光荣革命”?对17世纪英国革命史的研究,中国学界从未停止,但是在对这场革命性质的认识上,长期以来没有变化,即从专题论著到一般读物,从大学课本到中学课堂,只采资产阶级革命一说。
这不能不令人感到困惑。
事实上,自20世纪80年代以来,中国的英国史研究在不断深入,并取得了许多有深度、能体现中国学者话语特色的新成果。
为了及时、充分反映这方面的新进展,本刊从本期起,将连续三期登载南京师范大学姜守明教授关于17世纪英国革命史的专题文章。
在这些文章中,作者将这场革命放入16~17世纪社会转型、民族国家建构这个长时段加以考察,把17世纪中叶的革命和1688年“光荣革命”看做是同一场革命的前后两个阶段,详细探析了17世纪英国革命史所呈现出来的三重悖论,即革命与暴政的悖论、革命与独裁的悖论、革命与妥协的悖论,进而得出了关于这场革命同时具有清教革命和宪政革命双重属性的结论。
这不仅为我们进一步理解英国革命史提供了观察问题的新视角,也为我们揭示了英国在迅速崛起成为世界强国的过程中追求传统与变革之间平衡的政治文化奥秘。

3. Bodin让·博丹(Jean Bodin, 1530-1596),16世纪法国伟大的政治思想家,近代国家主权学说的创立者。
博丹所生所处的是一个动荡不已的时代。
16世纪下半叶,法国国内的天主教徒和新教徒(胡格诺教派)为争夺政治权力,多次发生内战,而每次内战又会引起外国干涉。
在这种情况下,温和的天主教徒与温和的新教徒组成一个“政治家集团”,他们中的理论家提出,法国迫切需要重建国内秩序,实现社会安定,为此,必须确保国王至高无上的权威,国王必须强大到足以将法律强加于国内其他所有的人。
博丹是政治家集团的重要成员和理论家。
他目睹了长期的宗教战争对国家和人民造成的重大危害,认为要保全法国的完整和安全,必须实行宗教宽容,所有法国人都必须放弃激进主义而选择“一种现实的稳定”,此即强大的王权。
为此,他于1576年发表《论国家六书》(Six Books on the State),从世俗的角度,首次系统而详尽地阐述了国家主权理论。
他写道:“主权是国家的绝对和永久的权力,是最高统治权。
”他说,主权概念是理解国家实质的最主要的和最重要的一点,一旦人民将这种绝对权力授予一个人——博丹倾向于国王,那么他就是一个主权者。
除了上帝,没有人拥有比他更大的权力。
博丹还具体阐述了主权的绝对性、永恒性、不可侵害性和不可转让性,指出只要国家存在,主权就存在。
博丹的国家主权思想提出后,陆续为欧洲政治思想家广泛接受并传播,从而为各国的君主专制统治提供了理论依据。
它对现实主义的影响亦是不言而喻的。
本篇选自《论国家六书》。
The SovereigntyThe state is a lawful government, with sovereign power, of different households1 and their common affairs. We put this definition at the outset because in all things, it is necessary to look first for the chief end, and then for the means of attaining it. A definition is nothing else than the end of a problem that is being considered, and unless it is well founded, whatever is based upon it will soon collapse.Let us now examine each part of the definition of the state. In the first place, we speak of the state as “lawful government” in order to distinguish it from bands of robbers and pirates, with whom it can have no part, commerce, or alliance. In all well-ordered states, therefore, robbers and pirates have always been excluded from recognition, whether it be a question of making a pledge in negotiating peace, calling off war, setting up offensive or defensive alliances, defining boundaries, or settling disputes between kings and territorial rulers.2The law of mankind sharply differentiates between wartime enemies who maintain lawful government in their states, and brigands and pirates who seek to subvert and destroy them.Sovereignty is the absolute and perpetual power of the state, that is, the greatest power to command. It is necessary to arrive at a definition of sovereignty because neither jurists nor political philosophers have so far defined it, although it is the principal and most urgent point for an understanding of the nature of the state. Having said before that the state is a lawful government, with sovereign power, of many households and their common affairs, the meaning of sovereign power mustnow be explained. I have said that this power is perpetual, for absolute power may be given to one or several for a certain time only, at the end of which they are subjects again. While they are in authority they still cannot call themselves sovereign rulers, inasmuch as they are only custodians and keepers of sovereign power until it shall please the people or the prince to recall it, just as those who have lent or pawned their goods to others remain the true owners and possessors. Likewise, those who give to others the power and authority to judge and command for a defined period of time, or to be recalled at pleasure, retain power and authority that the others exercise but in the nature of a temporary lease or loan. The governor of a country or the lieutenant of a prince surrenders his power at the expiration of his term, being but the depository and keeper for someone else. It makes no difference whether the official is of high or low rank. If the absolute power granted to the lieutenant of the prince were sovereign, it could be used against the prince himself, who would be left with nothing but an empty title, and the subject would command his lord, the servant his master—which would absurd. Whatever power and authority the sovereign prince confers upon others, his own person remains excepted. He always retains more authority than he gives away, and he is never divested of his right to command and examine his officials by way of prevention, concurrence, or challenge, to withdraw their authority altogether, or to permit it to go on to the extent, and as long as, it shall please him.If the people grant annually absolute power to one or several citizens, without control or appeal, shall we say they possess sovereignty? Only he is absolutely sovereign who, after God, acknowledges no one greater than himself. These citizens elected to highest office therefore do not possess sovereignty, as they are but trustees of the power lent to them for a given time. The people do not deprive themselves of sovereignty when they entrust absolute authority to one or several rulers, either for a limited time set in advance or to be revoked at their pleasure. In both instances the holders of power remain accountable to those from whom they have received the power to command. This is not true of the sovereign prince, who is accountable to God alone.But suppose such absolute power be given to a king’s lieutenant for life. Is that not sovereign and perpetual power? Otherwise, if we should call perpetual power only that which never came to an end, sovereignty could exist only in aristocratic and popular governments that do not die. Or if the word “perpetual” would apply to a monarch and his heirs, there would be few sovereign monarchs, in view of the fact that only very few monarchies are hereditary, and in view of the fact those who arrive on the throne by the right of election would not be sovereign. “Perpetual” therefore means the lifetime of him who has the power. If the sovereign magistrate, elected for a year or for a defined time limited, continues to exercise the power that has been entrusted to him, he must do so either with the acquiescence of the governed or by force. If by force, the tyrant is sovereign, just as the violentpossession of the thief is genuine possession in nature, although contrary to law, and they who had possession before, no longer have it. But if the magistrate continues his sovereign power with the acquiescence of the people, he is not a sovereign prince, as he exercises it only on sufferance; he is even less sovereign if his term is not defined in advance, as he then holds whatever authority is his as a temporary trust and loan to be revoked at pleasure by the people.Let us now examine the second part of our definition, and ascertain what the words “absolute power” mean. T he people or the aristocracy in a commonwealth may purely and simply give someone the sovereign and perpetual power to dispose of their property and persons, and of all state, as it may please him, and afterward leave all to whomever he may choose; just as an owner may give away his goods purely and simply, without any cause other than his liberality. Such a gift is a true one, with no conditions asked or received, once the donation is transacted and accomplished, whereas gifts that are granted under charges and conditions are not true gifts. Likewise, the transfer of sovereignty to a prince with charges and conditions does not result in true sovereign authority or absolute power, except when the conditions thus attached to the creation of the sovereign are of divine or natural law.A prince is not bound by the laws of his predecessors, and much less by his own laws and ordinances. It is possible to receive a law from someone else, but it is impossible, in the nature of things, to give to oneself a law tha t depends on one’s own will, as is stated in the legal maxim: “There can be no obligation that derives its validity from the will of him who makes the promise.” This necessary reason evidently proves that the prince cannot be subject to his own laws. As the Pope never ties his hands, according to the canonists3, so the sovereign prince cannot tie his hands, even if he desires to do so. Therefore we see at the end of laws and ordinances the words “Because it has so pleased us”, in order to indicate that the laws of the sovereign prince, though they may be based on good and valid reasons, depend nevertheless on nothing but his pure and free will.As for the laws of God and nature, all princes in the world are bound by them, and they have no authority to violate them. In so doing, a prince would become guilty of high treason against God and of making war on him, under whose greatness all the rulers on earth must bear their yoke and bow their heads in fear and reverence. The absolute power of princes and lords in no way extends, therefore, to the laws of God and nature, and the Pope who has best understood the nature of absolute power and who has brought kings and emperors under his control said that a sovereign can abrogate ordinary law but not divine or natural law.But is a prince not subject to the laws of his country, which he has even sworn to keep? A distinction has to be made here between two possible situations: if the prince has sworn to himself that he will abide by his laws, he is no more bound bythem than by any oath made to himself, just as private citizens are not bound by oaths on agreements that the law does not consider binding, however honourable and reasonable they be. If the sovereign prince promises, however, to another ruler to keep the law that he or his predecessors have made, he is obliged to abide by them, if the other prince has an interest therein, although no oath was included in the promise. But when the ruler, to whom the promise has been made, has no interest in the matter, neither the promise nor the oath is binding.The same holds true if the promise has been made by the prince to his subjects, either before or after ascending the throne. Not that the prince is bound by his own laws or those of his predecessors, but anyone, ruler or subject, is obliged to keep his just covenants and promises, whether made under oath or not. Similarly, as a private citizen may be relieved of an unjust and unreasonable promise that grieves him too much and into which he has been beguiled by trickery, fraud, error, force, or fear, so as to cause him major damage, the prince, too, may be released from promises that affect the diminution of his majesty, if he is a sovereign prince. Our general rule thus remains, that the prince is not bound by his own laws or those of his predecessors but is obliged to keep his just and reasonable agreements, in the observance of which his subjects in general, or a particular private person, may have an interest.Law and contracts must not be confused. Law depends on him who possesses sovereignty, and who can bind all his subjects but cannot bind himself. By contrast, a contract is a mutual obligation between prince and subjects that binds them reciprocally, and it cannot be altered except by mutual consent. In this situatio n, the prince is in no way above the subject, except that, when the justice of the law he has sworn to maintain has ceased to exist, he is no longer bound by his word; this the subjects cannot do, in their private agreement, unless they be relieved by the prince.The sovereignty of the monarch is in no way altered or diminished by the calling together and deliberations of the estates. On the contrary, seeing all his people recognize him as their sovereign, he finds his majesty thereby enhanced and more illustrious. In such representative assemblies the princes are not unwilling to grant their subjects concessions and favors that they would not otherwise yield, as they are overcome by the requests, petitions, and just grievances of the people, suffering most often without the knowledge of the prince, who sees and hears but through the eyes, ears, and reports of others. We thus conclude that the principal aspect of sovereign rule and absolute power consists in making general laws for the subjects without their consent. Without looking at other countries, we have often seen in our own realm that general custom has been abolished by the edicts of our kings, without hearing the estates, when the injustice of common law and custom was clearly to be seen.But what if the prince forbids to kill, under the sanction of the death penalty, is he then bound by his own law? I say that such a law is not his, but the law of God and nature. In fact, he is more strictly bound by it than are his subjects, and cannot be freed from its obligation by the people or the senate, being held responsible by the judgment of God, as King Solomon4 said. Marcus Aurelius5 said that the magistrates are the judges of private individuals, the princes of magistrates, and God of the princes. Such were the views of two rulers who have been held among the wisest. I shall conclude with that of Antigon,6 king of Asia, who, on being told by a flatterer that all things were lawful to kings, said: “Yes, to barbarian and tyrannical kings.”The first characteristic of the sovereign princes is the power to make general and special laws, but—and this qualification is important—without the consent of superiors, equals, or inferiors. If the prince requires the consent of superiors, then he is a subject himself; if that of equals, he shares his authority with others; if that of his subjects, senate or people, he is not sovereign. The names of notables that one sees affixed to laws are not put there to endow them with authority but to serve as testimony and additional weight.Quoted from Jean Bodin, Six Books on the State, in William Ebenstein, ed., Political Thinkers: Plato to the Present (New York, 1960)1 household, 一家人,这里指a group of people, 含有“民族”之义。
