Happiness or well-being is the ultimate value of human's pursuit. The most important mission for numerous subjects of knowledge is to find the way to promote human's well-being. For a long time, the lack of material wealth is the main obstruction to the improvement of human's well-being. Therefore, the study of wealth is regarded as the most important issue in economics. With the soaring development of material wealth, however, the level of human's well-being improved slowly. Even in some areas, the development of economy contrarily lead to the decline of local level of well-being. The social development evaluation system, which takes the GDP as the core, has been questioned widely. The study of well-being in economics experienced a process from the deviation to return. Actually, the study on the Economic Well-being Index (EWI) is not only one of returns of economics, but also it is the need to revise the social development evaluation system, build the harmonious society and achieve the scientific development. As a new research area, the study of well-being has not been done very well both in home and abroad, especially in the issue how to evaluate the well-being from the point of economics.This thesis systematically reviews the deviation and return of the well-being study in economics. Based on the comments of former achievements, this essay focuses on the elaboration of relevant conception and connotation in"Economic Well-being", as well as its measurements and influence factors. Besides, it constructs a calculation model of Economic Well-being Index by mathematical method, takes panel data of G20 in 1990, 2000 and 2009 as samples, and uses this model to investigate the Economic Well-being Index in China. Additionally, it proposes some policy suggestions for how to improve economic well-being level in China on the basis of analysis results.This thesis comprehensively adopts the methods of literature research, qualitative and quantitative analysis,?dynamic and static analysis,?positive and normative research to study. It is divided into 6 parts: the Introduction illustrates research background, method, significance and innovative points; Chapter One reviews the related theory and literature;Chapter Two elaborates theoretical basis of Economic Well-being Index;?Chapter Three constructs the calculation model of Economic Well-being Index; Chapter Four is going to investigate the Economic Well-being Index in China; Chapter Five proposes policy suggestions of how to improve economic well-being level in China.Generally, this thesis shows 3 innovation points. First of all, it puts forward and discusses two new concepts of"Economic Well-being"and"Economic Well-being Index". Secondly, it attempts to combine qualitative analysis and quantitative analysis to construct an accounting system of Economic Well-being Index based on the fundamental theory of economics together with mathematical method. Thirdly, it takes an investigation to the Economic Well-being Index in China and proposes directed policy suggestions through the connection between theory and practice. |
