中文摘要：

在斯密及其以前的经济学中，“幸福”有重要位置。但欧美国家主流经济学后来的发展，“幸福”却忽隐忽现、时有时无，甚至被完全剔除。直到1970年代，“幸福”才又重归经济学的学术视野，并被越来越多的学者、官员和民众认定为是经济增长和发展的终极目标。幸福经济学一是“幸福回归经济学”，因为没有幸福的经济，是“视障”，走不对方向；二是“经济学进入幸福”，因为没有经济学的“幸福”，是“肢障”，走不快、走不稳。幸福经济学不再认为幸福只是诸如伦理学、心理学等学科的研究领地，用经济学一套已经非常成熟的方法和工具，分析幸福的成本、幸福的效率、幸福的最大化等问题。以幸福经济学为视角，对于传统经济学的财富、成本、效用、消费、人性、方法等基本术语进行重新解读，既拓展和丰富了经济学的理论内涵，也使得相应的政策建议更贴近现实生活中最广大人民群众的真正需要。

英文摘要：

＂Happiness＂ was important in Smith＇ s and former economics. However, with the later development of mainstream economies in European and American countries, ＂happiness＂was nickering, or even got rid of. Till the 1970s, ＂happiness＂ re - entered the academic vision of economics, and more and more scholars, officials and people regard it as the final goal of economic growth and development. First, happiness economics is ＂happiness regression economics＂. An economy without happiness could have＂visual obstacles＂ and will lead nowhere. Second, ＂economics joins in happiness＂, for ＂happiness＂ without economics could have ＂body obstacles＂, and it won＇t go fast and steadily. Happiness economics does not consider happiness as the unique field of ethics and psychology, and it adopts the matured methods and tools in analyzing the cost, efficiency and maximization of happiness. On the perspective of happiness economics, the re -explanations on the basic terms in traditional economics, such as fortune, cost, efficiency, consumption, humanity and method etc., not only expand and enrich the theoretical connotation of economics, hut also make the corresponding policy meet the real demand of most common people.
