数据表明世界人口经济生活水平大相径庭,不同时代各国人口消费观也相差甚远,从经济学角度可以从市场供需关系、成本效益比较、政府宏观调控综合影响、价值定律以及效用论五个方面解释。本文旨在以经济学原理解释消费行为,联系实证进行分析,最终得出消费观成因。 The data show that the world’s population has very different levels of economic life. In different times, the concept of population consumption in various countries is also far behind. From an economic point of view, it can be explained from the perspectives of market supply and demand, cost-benefit comparison, government’s comprehensive macro-control effects, value laws and utility theory. The purpose of this paper is to explain the consumer behavior by the principles of economics and to analyze it in the light of empirical evidence.
