Theoretical and Demonstrative Study Concerning the Belong to Betterment

J.S.穆勒曾说过，发达国家的地价会不断上涨，1985年开始的东京都周边地区地价的超常上涨就是“地价暴涨”。“日本国土狭小，土地生产率高，这些都是地价上涨的充分条件。随着国际化和转向软经济，估计土地价格的上涨被认为是1,000万亿日元的泡沫。这是购买美国土地的两倍。地价上涨的两极分化带来了极大的地区差距。更严重的是，贫富差距扩大到了极限，这种土地价格奇高的原因可以说是多方面的。一个强有力的原因是存在的制度，承认改善是由土地所有者垄断。如果增值税的征收者不够多，土地投机就会全面展开，并带来地价神话。如何明确地掌握这些收益，如何向土地所有者收取费用，目前还不清楚。由于这一点，在许多国家的重要性，收集的改善被指出，它没有在许多时候进行的阻力，土地所有者和技术限制。但最近在韩国，一项与改良有关的新法律。在日本，改良征收也是由土地基本法规定的。本文是对世界各国改善民生现状的研究和理论分析。

J.S. Mill one has said that the land Price in rich countries will keep rising, the extraordinarily high rise in land price of Tokyo Metropolitan Area Vicinity began in 1985 was exactly the "Skyrocketing Land Price."In Japan the national land is very narrow and the land Productivity is high, so these are enough condition of rising land Price. With the Internationalization and shift toward the soft economy is estimated that the rising land Price which is thought the bubble of 1,000 trillion yen. This amounts is twice as high as to buy the land of America. And an extremely large regional gap was brought by the bipolarization of rising land price. And it was more serious that the assets gap between the rich and the poor was extended to its limit.Many fact can be stated for the reason why this kind of extraordinary high land price may occur. One strong reason is the existence of the system that admits the Betterment are monopolized by the land owners. If the collector of Betterment is not enough, the land speculation will be in full action, and it likes to bring a myth of Land Price.By the way Betterment are not established even in its definition. And that the ways to grasp those gains definitely and to charge expenses to the land owners are not clear. Because of this as in many countries the importance of the collection of the betterment was pointed out, it was not carried out in many times with a resistance of the land owners and a technical restriction. But recently in Korea a new law connected with betterment. And also in Japan the collection of betterment was defined by the land basic law. This is a research in the present conditions of the Betterment in various countries and its theoretical analysis.
